I suspect Ramshot TAC would do very well with 250's but haven't tried it.
My CZ550 9.3x62mm shoots RL-15 and 286grn Barnes very well, but I have yet to be able the 270grn Speers to group... I have tried RL-15, BL(C)-2 and H414, but no luck... You wouldn't happen to be able to recommed any starting loads for either TAC or Varget with the 270grn Speer?? Regards, Peter

As far as I know, I was the first person to try Ramshot powders in the 9.3x62, about 6 years ago when I purchased my CZ 550 in that chambering. I worked up to 65 grains of Big Game with 286's and got superb accuracy (as in 3 shots touching or nearly so) in the 23.6 barrel, at right around 2500 fps. This is with the Nosler Partiion or Barnes TSX. I had it pressure-tested and it got around 60,000 psi. Charlie Sisk and I have since used this basic load in a number of rifles with uniformly excellent results.
Hunter would indeeed be a little slow, and I suspect Big Game would also be a little slow with lighter bullets, as it would require around 70 grains to get up to speed with 250's. It is a dense powder, but that much still might not fit in the case.
For 250's I use either Rl-15 or Varget. Nosler got their best accuracy with 250's with Varget, and I have found it to be slightly less temp-sensitive than RL-15, though both are good powders in that respect. I suspect Ramshot TAC would do very well with 250's but haven't tried it. ![[Linked Image]](http://www.bunduki.com/bob/other/93x62-barsness-handloader250.jpg) Cheers! -Bob F.

I chrono'd the 285 Prvi bullet at 2480 over 65.0 gr of Big Game. This was out of a 25.5" Lothar Walther barrel.

Asking in regards to accuracy, velocity, pressure & temperature stability. 41

John, Std or Mag primers with RS Big Game? Asked him directly & he likes standard primers with this cartridge and load. CCI 200 or Winchester
