Using these projectiles I've been getting 1/2-1 MOA groups consistently using H4198 from my 308 @115yd.
Been trying to transition over to using D4198 but I'm getting more like 2-3 MOA so far.
I run them through a push through sizer to .3085"
In 300blk using a reddot I get approx. 2MOA groupings @ 115yd.
