Has anyone used the Sierra 105's successfully (well-stabilized) with a standard 9.25 twist? I've got a Model 10 Predator Max 1 with 24" barrel.

Thanks,

I've tried H1000 and RL22 using 105 amax. RL22 had better results; better SD and ES with average velocity of 3050 fps out of 26" model 12 with 9.25" twist; groups 1/2 the size of H1000.

Anybody use IMR 7828 or 7828SSC? I have a box of 105's that I was going to try with H1000 and 7828SSC. I have H4831SC as well, but I'm thinking it might be a touch too fast.

Hi the H1000 and IMR7828 are very slow powders, so you can do a full case 44-46gr will get around 2900 fps, as far as the H4831 It's a little faster so I would start at 41gr and 2800 fps and creep up from there.

105's for groundhogs? They must be alot tougher than ones I kill w/ 58 vmax!! I'd be worried about ricochets too.

IMR7828SSC w/ 107 gr SMK.

I use three powders for .243 dependent upon bullet weight.
H414 58 to 80 gr bullets
IMR4350 81 to 100 gr bullets
IMR7828SSC for 105 gr bullets and above.

105s work great on groundhogs. Rips them almost in half with a conservative load. I don't really worry about ricochets with the ballistic tip target bullets. I have yet to see one make it out the other side of a deer. Could happen maybe, but have shot some and don't anticipate it. that said still take safe shots
