Re: 7mm dakota or 7lrm
6.5/300 ? Going for supersonic way out ? Keep us posted on how that works out. Starting my 5th firing today on 9 pcs. of 7 working it as little as possible. No visible issues as yet other than slight primer cratering w/215's, 68gr. N165, .310 NB, jam+.003, sending 175SMK 2945 av., 27" Still trying to find best load/wt. combo, best so far is 67gr..
Still working it at 2.49 and not yet had to trim, I'm going to keep working the same 9pcs. until visible signs start to show up but I believe I should get 10+.
