I am curious if anyone is running a necked up 408 Cheytac to 416. Is it worth the effort to get the better bullet choices at 416 and the higher weight bullet choices? What kind of speeds and barrel life are you seeing?
416 Cheytac???

Unless you already have a 408 sized action that you want to reuse why would you give up 40.7 grains of case capacity vs the 416 Barrett? The 416B has a case capacity of 200 grains vs 159.3 grains for the CheyTac case.

I have a spare 408 action. I might buy a bigger action next year and build a .50... but this is an experiment for my gunsmith and myself... we were able to scrounge a 37" 416 barrel and I had the action and a chassis laying around. We are currently awaiting the reamer. I will put info on my project up on here if anyone is particularly interested... if nothing else, we can scrap it a few hundred rounds down the road and put a 375 barrel back on it... i have a few of those laying around too.
2850fps with a 505 warner should be easy mode... The 41XC (long Lapua) will do that. I would bet the CheyTac would be closer to 2950fps
Look at the Badlands 400gr 375 bullet. For the 416, look at their 525. Better bc and easier on the wallet
True, I would go Badlands for sure, but CE was the only tested projectiles I could find info on at the time
They'll work, but when you can get a better performing projectile for less cost, why not? The A tips haven't really been out long enough for anyone to do much testing with them yet that I've seen
I will be working with the Warner Flatline 505's to start. Might get the tubb ring if I can get out the Kansas or Texas to shoot 2 miles or more.
I know this is an old thread but I happened to stumble across it looking for something else. I been shooting a 416 CT for a couple years now, my current fav load for the Hornady 500g A-Tip is 132g of Retumbo with F-215M primer in a BAT model M action fitted with a 34" 1 in 11" twist Lilja barrel, MV is avg 2867fps, my best groups so far is .45 moa. No high pressure signs, extraction is easy. I recently picked up some Viht N-568 powder, burn rate is similar to Retumbo, so I'll give it a try.
I run the 375 CT with 400gr Lazer with 131.5 of N570. Very accurate load. The benefit of using N568 or N570 is better case fill as the grains are so much larger the Retumbo. I have only had one hang fire and that was with Retumbo so having good case fill is important.
if it helps you a 416 Stroker is a cheytac improved case necked up to 416. Might be able to find more data that way
Yes, I agree on the N-568 granules, they are large enough to jam my electronic powder dispenser, I have to hand spoon the stuff in.
I also like the old classic buffalo rifles, the 1874 Sharps are my favorites so last year I built one up on a C-Sharps reproduction action chambered in 500/416 Nitro Express, which is a creation from Krieghoff for their double & single shots, I tried 6 different powders in the test runs and found that N-568 was the best, it gave highest MV's lowest ES and best groups, no pressure signs and easy extraction, the stuff is pretty amazing in its performance.
