416 Ruger DGS 400 grain on Xero C1 Pro Chronograph

[Sammcc73]

Was playing with my New Garmin Xero. Since i just got my Ruger recently I wanted to see what the Factory ammo looked like on Paper (so to speak) It was 54 degrees F when this group was shot. I must say its pretty good data. this is from a 20" barrel Guide Gun.

So only about 100fps loss going from the 24" to 20"? Not bad.

 

[450 Dakota]

Really good standard deviation on the factory ammo.

this was from a 3 shot string of the Buffalo Bore 350gr TSX

I've always found speed resting factory loads to be interesting. Do it with enough brands and you start seeing patterns. Hornady tends to run hot and will even show pressure signs in some guns.

That load is impressive. I have not seen any of those in my local area. I was interested in running some across the chronograph. Thanks for sharing the info on this and the Hornady.
I am a fan of the 416 Ruger cartridge.

Just read a review on the Garmin Xero. Apparently the new champion in the chrono world.

I have seen another chronograph report of the 2650'ish fps average of these loads from a 20" barrel.

My load work is paused until winter is done. I would be very content in the 2550 fps range with that bullet. I am still playing with the 350 grain TTSX. I have loaded it to 2560'ish average without obvious issues. Currently, I have it at about 2525 fps. I may leave it there, or drop it to my original goal of 2500 fps. I want repeated loadings on the same brass for a better idea. I am loading a bit longer than the SAAMI COAL, within a standard magazine. The boat tail of the TTSX definitely adds length to bullet inside the brass.

I am also anxious to chronograph the 350 grain TSX (powder change), Hammer Bullets 325 grain Shock Hammer, and the CEB 325 grain Maximus. The 325's are a little shorter in length than the 350 grain TSX. I am guessing 2575 fps will be relatively easy with the 325's. But, still a guess at this time. They all differ in design characteristics.

Its pretty darn good. I have used is only for rifle so far. I need to Set-up a crossbow i accuired , as well work on some Slug loads for the shotgun . You just set it on the bench point it inline with the barrel and start the session and shoot. about the size of a pack of smokes.. Its worth the extra 100 over the Lap radar. IMO I had a MagnetoSpeed Sporter ( which is for sale in the Gear section)

I pulled a bullet from one 350TSX's from Buffalo Bore it had 82.3 grains of a ball powder in it and the Lehigh defense 350 wide nose solid had 83.2 grains of a ball powder in it. (sacrificed one of each for curiosity sake) and to get an idea of where to start . I bought 100 TTSX 350s to play with some of the same 350 solids from Lehigh and some speers. I am just shooting thought the few factory boxes for BIG bore practice and to get brass. If I can get the TTSX's to 2660fps the should still have around 2000fps at 300y they have a .444 BC. I cant be for sure what powder it is. Looks alot like CFE223 which i have , Does not look like RamShot BigGame . Most likely it 2000MR ( disclaimer this powder data for for curiosty only) the only 350 load data i have is from the Speer Manual volume 15#

I am using the 2000-MR with the 350 TTSX. I referenced the Speer #15 also. My velocity goal was 2500 fps out of my 20" barrel. What I did not have was the actual Speer bullet to visually compare. I am going to try and order some for actual comparison purposes.

I am most certainly not saying the below is correct.

My extrapolation thought process with the 350 TTSX went something like this :

I subtracted 100 fps from their 24" test barrel compared to my 20".
I subtracted another 100 fps from that remaining velocity, for difference in bullet length and additional bullet length inside the case.
This left me with a hypothetical 2531 fps as maximum. COAL of 3.370" was my target length, though some were 3.350". Light crimp with a Lee Factory Crimp Die. This seated about middle of the top band.

I loaded various charge weights.
I / the chronograph missed some shots on the range with some of the loads.

My highest charge of 86 grains gave me a 3 shot average of 2558 fps. No "visible" signs of excess pressure. No issues with bolt lift, extraction, or primers. Accuracy was very good. Without actual pressure data, I called this my absolute maximum.

85 grains, gave me a 3 shot average of 2524 fps. This is currently my load. I still need to reload the same brass a few times to see how it holds up. And, I want to actually compare Speer's bullet at their COAL and various charge weights.

I "think", I am pretty comfortable with the 85 grain load with the 350 TTSX. The 350 TTSX basically has the boat tail length of more bullet in the brass, than the TSX version.
With its BC, 2500 fps and a 2" high at 100 yards sight in, it gives me an easy 250 yard trajectory for anything I will be using it for. Remaining velocity at 250 yards should be sufficient for bullet performance.

I am anxious to chronograph the 325 grain Hammer Shock Hammers and CEB Maximus. Their bullet length is more in line with the TSX.

that makes me really Curios what powder is in there????

He may or not, be using a powder not available to over the counter sales.

I have some of the TSX loaded for comparison to equal charges of the TTSX. The shorter flat base TSX, may very well exceed the velocity of the longer TTSX boat tail, with the same powder charge. But, winter weather has range time on hold.

Edit: I would also love to know, what powder he uses.

Its pretty darn good. I have used is only for rifle so far. I need to Set-up a crossbow i accuired , as well work on some Slug loads for the shotgun . You just set it on the bench point it inline with the barrel and start the session and shoot. about the size of a pack of smokes.. Its worth the extra 100 over the Lap radar. IMO I had a MagnetoSpeed Sporter ( which is for sale in the Gear section)

Any real advantage over Labradar besides size?

If you already have a Lab Radar I would say NO for an average reloader/hunter. if you are in the PRS/Comp/Benchrest Game it would be worth the switch for the fact you can rifle mount it and have real time speed data to adjust fire at long range, if you were buying a radar chrono I would pick it over the Lab Radar. One PRO, The Lab radar does Calculate BC the Garnin does Not . I don't Rely on balistic tables. I always get my own real world drops from 100-500y . I am interested in setting it up at the Target to see true impact velocities, the size would be easy to shield if on a public range.

 

[ldmay375]

Additional load data from Federal's site for comparison. Per Federal info, this bullet is 1.487" in length. I measure about 1.5960" for the 350 TTSX. A difference of about .109" longer for the TTSX.
But, my COAL is about .100" longer than they are seating this 400 grain. Plus the boat tail of the TTSX takes slightly less space than the flat base at equal depths.
For my rifles without pressure test data, I am calling the 2000-MR, 85 grains at 3.375" COAL my maximum. I have "guesses" that it could be loaded faster.

 

[ldmay375]

Fyi, I see another Federal "discontinued" listing of the .416 400 grain Trophy Bonded Sledgehammer Solid, listed as a 1.380" length. Not sure which one is the current. I don't see a product number for either.
I wonder if that length was a typo, or for the older non grooved version ?
