dse Report post Posted August 3, 2014 I've had really good luck with rl-22 but have only used Barnes and swift tipped 130gr Share this post Link to post Share on other sites
Pine Donkey Report post Posted August 3, 2014 IMR4350 is awesome...I'll trade you some for that H1000! Share this post Link to post Share on other sites
5guyshunting Report post Posted August 3, 2014 I found a load on real guns for sierra 140s , 66 grains imr 7828 cci mag primer . Every thing matches , I may start there. Tombstone is a long ways to trade powder. Brunos here in phoenix had lots of powder, but they are charging about $12.00 more a pound than other places.

nighthawk Report post Posted August 4, 2014 In my wife's 270win I have had good results with 150lrab and h4831sc. On the slow side at 51.5grains but produces a 5/8 group at 100. She can even shoot 1" groups with bipod and rear bag Share this post Link to post Share on other sites
Sonof12 Report post Posted August 4, 2014 Not what you've got but I've tried those powders and nothing did better for me than a higher dosage of r-22 w 140 accubonds. I'm trying magpro this weekend so we'll see with that. Share this post Link to post Share on other sites
