I bought a few bags of the 115&120 partitions from sps a few weeks ago….was really hoping they’d shoot but the gun seems to hate them. Like 3-4” 3 shot groups at 100 yards.
I tried the 100TTSX with two powders, H4350 and RL23 from .025-.085” off the lands and they shot from ok to bad….and yes I thoroughly cleaned the rifle before shooting the barnes bullets. I’ve been using Cci match primers…. I might try a different primer and a quicker powder…it’s perplexing, aggravating and getting expensive!
