[QUOTE="RCMSTER, post: 2800866, member: 54689"] Ok. Let me try answering some questions. I’m using WLR primers. Barrel is not factory. It is a 25” Hart, installed by Diamond T rifle shop out in Idaho. He also did some accuracy stuff to the receiver. Stock is a McMillan HTG, pillar bedded and glass bedded. I stopped at 52 grains because thats where the load was most accurate. Powders I also have is IMR4831, A4350, R-17, Magpro, H4831SC, maybe a couple others that I’m not remembering. Seating depth is the one thing that worries me a bit. I have to seat this bullet way deep. Max length to the lands is 3.055”. Don’t really like that aspect, but it is what it is. The scope I have mounted is a Weaver Grand Slam Tactical, 3-15 mil/mil. Barrel probably 100-150 rounds through it. Last cleaned about 10 rounds ago with Montana Extreme copper killer, followed by a repeat clean with Butch’s Bore Shine. Brass is twice fired Norma. I tried crimping, and that had no effect. Groups were still 3-4”. I hand weigh each charge using an RCBS 1010 scale. Cases are full length sized using Redding fill length bushing die. Also tried increasing interference fit to approximately .004. Also had no effect from previous fit, so basically, I’m out of ideas on where to go next. [/QUOTE]
