You should be alright with any powder between powder in the burn rate chart between Benchmark and IMR 4895. I have my best luck with BLc-2 powder in this case as a rule. For the T/C you will want to shot 50 grn. bullets most likely, and I recomand the Serria Blitz Kings. For the 1 in 9 twist you`ll do better with 60 grn. bullets. I also seem to have my best groups with Rem. 7 1/2 primers. It these are factory chambers you`ll probibly want to set the bullets as far out as you can get them also. With the T/C that`s no problem, but with the Rem. you may get you best accuracy with ammo that is to long to fit in the magizine. Hope this helps alittle.
