You don't state what the load is so it is hard to give advice, I've had 4 .243's over the years and I don't have much luck
with them, one thing I have found they don't shoot the best with 100 grain projectiles I've had the best accuracy with 85 to 90 grain
and powder in the 2209 burning range. Robert.

Pretty standard 1:10 barrel twist result. The 95 Targex is available in two variants for fast or slow test barrels. W760 should work well, and I have found slower powders are fine 22013SC, 2217 (if you can get enough in). I use RL22 and N165 in my 243AI.
I don't like the nickel cases. Very hard to size so I would guess neck tension would be hard to keep consistent? Cant really see it making a big difference with hunting rounds though.
