My kids each use Remington ADL .243s to deer hunt. One is stainless, the other blued. Both have 24" barrels with a 1/9.125 twist. Both of them shoot the same accuracy nodes. Here are some loads the shoot under 3/4 MOA in both.
Sierra 85 gr HPBT Win Brass CCI 200 37.0 gr IMR 4064 (yields 2950 fps)
Hornady 87 gr VMAX Win Brass CCI 200 37.0 gr IMR 4064 (yields 2944 fps)
Nosler 95 gr BT Win Brass CCI 200 Over max charge of H4350 (work up to this charge and don't blindly use this) - yields 2936 fps - this load absolutely bugholes
Speer 100 gr BTSP Win Brass CCI 200 Over max charge H4350 (work up to this charge and don't blindly use this) - yields 3025 fps - this load absolutely bugholes
Lastly, the Sierra 85 gr HPBT and the the Speer 100 gr BTSP shoot to the same POI at 100 yards. This provides some flexibility based on what I want to hunt. I have more faith in the Sierra 85 gr HPBT than I do in the Nosler 95 gr BT. I've had the BT's come apart on shots under 100 yds and not provide pass-throughs. I'm anxious to see how the Speer 100 gr BTSP will perform.
