I once witnessed a friend shoot a recently acquired .270 Winchester with some handloads that came with it. The first shot sounded very odd and a lot of smoke came out of the action. The ammunition box was labeled .270 Winchester and all of the cases were head stamped the same. Upon further...

If you have some evidence that case shape affects burning rate I would very much like to see it. If I am proven to be wrong I will gladly change my opinion and thank you for setting me straight. Allow me to quote from The Big Book of Gun Gack (Barsness, 2015) page 309. "A few years ago my...

As I said in the second post on this thread, 8208 is my favorite powder for the .350 Rem Mag. Hodgdon data for the .35 Whelen is suitable since the Rem Mag and Whelen are nearly identical in case capacity.

I have Model 600 that is surprisingly accurate with 250 Noslers. Its favorite load is 54.5 gn of 8208. 58 gn of Varget is also excellent, followed by 54.5 gn 4166 and 53 gn of Benchmark. The Benchmark load produces excessive pressure at temperatures over 80F while the others have been just fine...

Either 180 or 165 Speer should work just fine. If preventing blood-shot meat is a concern I recommend 200 gn bullets. They are almost as flat-shooting as 180s when loaded with StaBall 6.5, Reloder 16 or 560.

No elk but I did get three mule deer with the .375 using 285 gn Speer Grand Slams. Hunting in rather thick timber, the farthest was about 35 yards. All died quickly and the remarkable thing, to me, was that there was no ruined meat. To quote an old cowboy named Elmer, "You could eat right up to...

Though the base to shoulder measurement of the .358 Norma is Nominally .045" greater and the base to top of shoulder is .022" greater, I have fired full-powered loads from necked up, and not fire-formed, Winchester .338 brass with perfect satisfaction. And then loaded and fired those cases...

Of the powders you mentioned H4831 is just too slow burning and high velocity could not be achieved. The IMR powders mentioned are on the fast side but 4064 would probably be OK with the lighter bullets. My rifle has a 24" Schilen barrel with a 1:12 twist and is very accurate with the following...

I tried necking .300 H&H cases up with a .35 cal tapered expander die. An application of case lube made the operation go smoothly. I then resized them with a .300 H&H die, gradually adjusting until they would just chamber easily. This seems to have solved the shoulder datum problem. I will try...

Thanks for the tip on the brass. I will try necking it up to .35 caliber and then resizing. Maybe that will reposition the datum line.

My #1 likes: 200 NP 66gn N560 or 74gn StaBall HD 180 TTSX with 69gn R23 or 70gn R26 My X-Bolt likes: 200 NP with 75gn Magnum, 65gn R23 or 68gn R26 180NP with 68gn R23, 69gn H4831 or 72gn R26 Have not been delighted with Hornady brass. Some cases had head separations on the first firing, some...

My .358 Norma has a 24" Schilen barrel with a 1:12 twist. 225 TSX at 2920 with Varget or H4350. 250 Nosler at 2800 with H4350 or Big Game. 280 Swift at 2650 with H4350. 310 Woodleigh at 2500 With H4350. .338 Win cases work just fine without fireforming. I don't know about Shaw barrels but have...

I have been using Geco cases and Federal 210 primers. Velocity from my 22" barrel Ruger #1: 250 NAB 62.5 gn N140 or Varget - 2640 fps 286 Hornady 56.5 gn N140 - 2313 fps 286 Hornady 58.5 gn N540 - 2400 fps 286 Nosler 66 gn Big Game - 2480 fps The 286 Hornady loads were chosen for accuracy. I...

I like 250 Accubonds with 62.5 gn of N140 or Varget 286 Hornadys with 56.5 gn N140 or 58.5 gn N540 286 Noslers with 66 gn Big Game

I was beginning to think that I was the only one with a .416 Howell. Had mine made up in 1983 and it got me a very nice cape buffalo with Hornady 410 gn solids and 760 powder. These days I use 400 Barnes Banded Solids with Varget or 350 TSX with AR-Comp. The above two loads go into the same group!

I have doubts that the improved cartridges would feed reliably from the tapered H&H magazine. My favorite H&H loads consist of 180 TTSX with Reloder 26, Reloder 23 or H4350; 180 Hornady SP with H4350; 200 Partitions Reloder 23, Reloder 26 or Magnum. 215 primers.

Nevada Mike, I think we are on pretty much the same page. I do not advocate using published 7-08 powder charges. My claim is that if one works up to 7-08 velocity, assuming the same powder and adjusting for barrel length, the pressure will be very similar. I got the idea from John Barsness' Big...

According to the latest Speer manual one can expect velocity to decrease of about 20 fps per inch of barrel less than 24 inches. The 7x57 has a maximum average pressure of 51,000 psi compared to 61,000 psi for the 7-08. The 7x57 has a slightly greater case capacity than the 7-08 Rem so 7-08...

You might check your expander ball. It should have .003" smaller diameter than the bullet diameter. If necessary chuck it in a drill and reduce it's dimeter with emery cloth.

I agree with using magnum primers with powder charges above about 60 grains, especially in cold weather. Magnum primers often work better with spherical powders, even in relatively small cases like the .220 Swift. WLR seem to be the "hottest" of the standard primers.

Many years ago, my father father finished loading a batch of .44 Magnum with 296. He then emptied his powder measure into a can of 760 that was also on his bench. I borrowed said can of 760 to try some loads in my M77 .220 Swift. The floor plate was blown off and wrecked, the stock split and...

In my #1 300 gn Northfork, Hornady and Barnes X all worked well with Benchmark, TAC, Varget and 8208. Hodgdon has data. 400 gn Woodleigh (.411) were excellent with 8208 or Reloder 15. 400 gn Hornady (.410) scattered all over and hit the target sideways if at all. For a very light load I used...

I didn't do a lot of experimenting with 4451 in the 30-06 because accuracy was not outstanding. Custom Springfield - 22" Douglas barrel. 190 Nosler Accubond Long Range - 54gn - 120 primer - WW cases - 2451 fps and 200 Nosler partition - 53gn - 210 primer - LC76 cases - 2520 fps gave reasonably...

My 7x57 seems pretty fussy when it comes to powders. The 145 gn LRX is great with StaBall 6.5. 150 Nosler Ballistic Tips were god with 4451 and Reloder 26. Not so great with StaBall 6.5. I used Hodgdon 7-08 data and worked up to the listed velocity,. Since the two cartridges have virtually...

From Barnes Reloading Manual Number 3: Case - Remington, Primer - 215, Barrel - 24" AA 2520 - 69.0 to 74.0 gn 2413 fps RL 15* - 73.0 to 78.0 gn 2489 fps H4895* - 69.0 to 74.0 gn 2405fps H380 - 76.0 to 81.0 gn 2392 fps IMR 4320 - 69.0 to 74.0 gn 2374 IMR 4064 - 69.0 to 74.0 gn 2410 fps *...

With 250 Accubonds good groups were achieved with the following: 59 gn AR-Comp - 2560 fps 59 gn IMR4166 - 2620 fps 62.5 gn Varget - 2650 fps 62.5 gn N140 - 2640 fps All loads were good but N140 was outstanding. Ruger #1 22" barrel - 210 primers - Geco brass

In the 9.3x66/370 SAKO I use 68 gn of Big Game and 215 primers behind a 286 Nosler for close to 2500 fps. Have had no measurable velocity increase at temps up to 90 F. In the 9.3x62 I use 66 gn and a 210 primer for 2485 fps (22" barrel) but have not tried it at high temps. Barsness reports that...

According to the Speer Manual #15 the 9.3x62 and cartridges of this approximate bore diameter lose about 20 fps for every inch less than 24 inches.

As Firebird said there are at least two generations of Grand Slams. They are not bonded but use Speer's Hot Core process. The early generation had a core of hardened lead in the rear and softer lead in the front of the core. The latest version seem to be much like their now discontinued Mag-Tip...

Found some reduced pistol bullet data for the 450/400 which should be pretty close. Below is the load data from Western on AA5744 Bullet weight: 210 grains. Low range load: 44.0 grains (ca 2100 Fps) Maximum load: 55.0 grains (ca 2580 Fps). Bullet weight: 225-230 grains. Low range load: 48.0...

In my experience N140 is very close to Varget in burning rate.

Reloder 23 and Vit N555 (and all Vihtavuori powders for that matter) are designed to be temperature resistant. Many modern powders, by design, burn most consistently and provide their best accuracy at 60,000 to 65,000psi and might show poor accuracy at low pressure. Powders whose velocity...

In my search for substitute powders for the 9.3x62 I found that Vihtavouri powders are working well. With 250 Accubonds N140 gave the same velocity as Varget with the same powder charge with better accuracy. With 286 Partitions N140, N150 and N540 were all good.

In bolt-action rifles I have eliminated irritating and inexplicable fliers by free-floating the magazine box. It might be worth a try in your case.

I suggest 150 Nosler Partition or Accubond since they expand reliably at the velocity you desire. TTSX would probably be OK. In either case I would load to the overall cartridge length listed in the manual. Barnes #4 says N550 is he most likely powder. The page copied from the Nosler in your...

" Loads for many cartridges have been reduced not because of an excess of caution but because more accurate pressure testing equipment has become available. Some published loads were found to be excessive when more accurate measurements were made. My own approach to loading the 7x57, in a...

I have two. A Deluxe .225 Win of 1964 vintage and a 300 Win vintage of 1970, since converted to .358 Norma. Both are excellent rifles.

63 grains of IMR4350 is two grains less than the maximum load in the Nosler Manual. You might try increasing the powder charge slightly. Modern powders tend to burn more consistently at 60,000 to 65,000 psi. I have produced very accurate loads in my 300 H&H with several bullets and powders...

The best loads in my Ruger 96/44 lever action, for 240 grain jacketed or 250 grain cast bullets, used Hodgdon Lil' Gun powder. Velocity and accuracy were far better than with H110. The only primer tried was the Winchester WLP "Large Pistol for Standard or Magnum loads".

The Internet Movie Firearm Database (www.imfdb.org) identifies the firearms used in a great many movies.

The .30-'06 does very well with a number of powders and 180 gn bullets. I have had excellent results with IMR4350 (of course), Hunter, Reloder 26, StaBall 6.5, N560, and H4350. My favorite is a load from Alliant data: 180 Nosler Partition and 56 grains of Reloder 16. Since I live in Montana...

Fine looking rifle. I had one just like it i .375 H&H and two friends had them in .338. In each case the stock split behind the magazine after a few rounds. The recoil lug was not supported by any wood but just the cross bolt. The lower edge of the recoil lug bore on the upper curve of the cross...

I have had good results with 250 Accubonds and 62.5 gn Varget and 286 Partitions with 66 gn Big Game. The point of impact of the 250s is about 5 inches higher than the 286s. Have some of each loaded with AR-Comp but haven't shot them yet.

I had a 5" Model B back i the '90s. It was very accurate and reliable. 125 grain factory ammuition chronographed at 1525 fps and it worked great with 158 grain hard cast bullets. I sold it only because Coonan began advertising a .41 Magnum version and i wanted to have some ready cash when it...

Model 70 Lightweight 22" barrel. 145 LRX worked up to 2930 fps with StaBall 6.5. 150 Nosler Ballistic Tip or Partition worked up to 2830 fps with StaBall 6.5 or Reloder 26. Have yet to try other bullets but these should do.

The only published data I could find for Vihtavuori powders in the .416 Ruger: 400 grain Hornady - 71.3 grains N140 - 2150 fps (Hornady Manual #11) By my calculations 73 grains should be a safe starting point for 350 grain bullets, with a maximum of 76 grains. 350 grain Speer - 81.6 grains N540...

I tried R16 in the very similar 9.3x66/370 SAKO and found that with the case filled to the neck a 286 Nosler Partition reached 2415 fps with good accuracy. I would expect a similar result in the 9.3x62 since it has only 4% less case volume. With the 285 gn Lapua Mega the same load reached 2470...

"A few years ago my friend Charlie Sisk, the well-known custom riflesmith from Texas, built a heavy-barreled .300 H&H and shot the rifle with half-a-dozen handloads in his indoor range. He then rechambered the same barrel for the .300 WSM and tried the same powders and bullets. Muzzle velocities...

Since the 300 H&H and 300 WSM are very nearly identical in case capacity I have been using 300 WSM data successfully. The Hodgdon 2021 manual has the following for 300 WSM and Varget, Winchester cases and WRM primers. 150 Speer GDSP 55.0 Varget 3008 fps 56800 psi...

Much like crs I lengthened the chamber of a .405 Winchester. Mine was a Ruger #1 and I was able to lengthen the chamber by .28", still leaving .25" of the bullet inside the case. The result were 300 gn TSX at 2550 fps and 400 gn Woodleigh (.411") at 2150 fps. The accuracy with factory length...
