Big Bore Addiction Group

[Velo Dog]

Marlin lever action .45-70's with similar modified features as Spike's Brockman custom are very popular here in Alaska for bear, moose, deer, bison.
Many people don't know that we have free roaming bison up around Delta Junction and a few permits are issued each year, through a lottery drawing system.
Up here, a hard cast, flat nose 400 grain bullet is very common with .45-70 shooters who hand load their own ammunition in that caliber.

If you are looking for some loaded ammo for a big bore you may check out some of the close out specials at CorBon.

Most are in boxes of 10 so be careful when comparing prices.

I bought several boxes of 505 Gibbs. At $5.00 per loaded round it is tough to beat.

There are 375 Flanged, 404 Jeffery, and 470 Nitro at less than $4.00 per round.

I picked up some 505 Gibbs ammunition from those closeout deals. hard to beat factory Gibbs for $5 a shot!

made it out to the range for little bit today with the 416 RM M70 and its new scope a Leupold VX-6 1-6x24. i didn't have much time so i just managed to get the scope mounted then get the scope zeroed at 50 yards with my fire forming loads (400gr bullet at 2100fps) using a lead sled and 50 pounds of lead bars. all that weight in the led sled made sighting the rifle in off the bench very easy. i got lucky and my fire forming loads actually shoot pretty well considering they were whipped up quickly to simply convert 375 H&H brass to 416 RM brass. my grouping was just under an inch at 50 yards.

for recoil sensitive people interested in a suitable light load, its a Hornady 400gr RNSP over 75gr of W760 powder. i imagine it would work just as well with the Hornady 400gr DGX or the Swift 400gr A-frame. a 400gr bullet at 2100fps is plenty suitable to take DG as proven by the 450/400 NE 3" which only spits 400gr bullets out at 2050fps.

i did have a little trouble when the recoil caused the cross bolts on my M70 to vibrate loose. but this was fixed with a little lock tight and shouldn't happen again.

Never saw it happen matt, but I've been warned not to put the big bores in the lead sled or if you do, only load it down lightly. The stout recoil against the sudden stop has apparently led to cracked stocks.

ive heard this before, but I don't believe it. if you think about how the lead sled works then you will realize that it isn't a "sudden stop". if the gun is properly sitting in the lead sled with the butt firmly against the back plate then the extra weight is simply added to the gun. the only way I could see the stock cracking from a lead sled is if you put a gap between the butt and the rear plate. having a gap would allow the gun to accelerate before hitting the weight which I could see breaking a stock. I suppose if you bolted your lead sled down to a concrete bench it could also cause the stock to break since there would be no give at all. but even with 50 pounds of lead, the sled moved backwards 2" with each shot and that was with light loads.

Yeah I'm not sure I believe it or not either. It may have happened, but perhaps it was only accelerating an issue that was bound to happen anyway. But along your line of thinking, the recoil pad does give the the stock a running start at the sled's back plate. It has to compress which of course is slowing it down a bit, but the stock isn't right up against that back plate. If the rifle is not properly bedded, the action will have that much more ability to smack the stock. But that would only be accelerating the issue of the rifle not being properly bedded.

I saw a absolutely stunning CZ 550 475 Lott on gunbroker this weekend, at a excellent price. It just wasn't the caliber I was looking for.......

while the recoil pad does allow some give its just as you said, its compressing and cushioning the blow to both the sled and the gun. if your recoil pad has enough "give" to allow the stock to accelerate to a point where it breaks then you seriously need a new recoil pad! like you said, if your stock breaks on a lead sled then it was going to break on your shoulder.

475 Lott? a typo or a cartridge I haven't heard of yet?

Thanks, 458 Lott

 

[matt85]

haha no problem, you had me checking gunbroker and the Wiki looking for a new cartridge.

I wouldn't be surprised in the least if someone invented a cartridge for bolt action guns that uses the .474" bullet.

While lurking about a Houston gunshow this weekend, I convinced my friend that was not yet above 40 cal to purchase a beautiful barely used Winchester 70 super classic in .458 WM, price negotiated for rifle, rings and two boxes of 515gr Remington fodder was 900 bucks. It was going home to my house if he didn't scoop it up although I need another .458 as much as a dog needs a side saddle.

That is one hell of a deal!

Good move, you are obviously a great friend to have. So now you need to take him with on a hunt for something big and/or nasty!

 

[Bullthrower338]

Prolly the best deal of the show, we got back to my house, pulled the rings off and sighted the iron sights for my 50 yd target. Shot very well. I was happy he made such a good buy!

he retires in a little over a year, we talked about a buff hunt when he retires. Hopefully I will have my double by then! Three more months and I can quit spending money on that dam frivolous truck payment and can sock more away for the rifle and hunt.

 

[ActionBob]

Bullthrower;
Glad are working on getting those priorities straight!

BTW, where can I get a sidesaddle for our dog? Seems like if only I could get a side saddle on the dog, I might just be able to justify another gun

Matt85,

Look up the .470 Capstick.
It's a wildcat cartridge, that is approximately/essentially the .458 Lott necked up to take projectiles otherwise designed for the .470 NE, in other words .474 diameter bullets, instead of the familiar .458 ones.

IMO, the .470 Capstick does nothing at all that the regular .458 Lott does not already do, except make finding factory live ammunition very difficult to impossible in a pinch.
But, some folks dig on cartridge wildcatting.
At the end of the day, wildcatters are still my cultural and political brothers, in spite of the fact that guys like me cannot figure out any point in it whatsoever.

Cheers,
Velo Dog.

 

[Bullthrower338]

I dabbled in a lil wildcatting, I mostly accomplished split case necks and frustration , decided to go back to fast guns and slow women, or maybe it was slow guns and fast women, whichever it was I can spend more time at that while I wait on factory cases with proper headstamp to arrive from midway. Lol

When people ask me how I can afford to hunt Africa one of my answers is that I drive an 11 year old truck that I plan on driving for another 9 years.
