Here is what I sent to North Fork after they sent me some 165gr to try again and 180gr for 300Win mag along with 200gr for my 358Win. I was able to get hunting accuracy (not what I am use to but good enough for hunting) out of the North Fork bullets.
Franz, I have some much better news. I am not getting 3" groups now. First, I think part of the problem with the 165gr SS I bought from Midway were that they were not cleaned well and there was machining residue in the grooves (every bullet in the box) defeating the very purpose of the grooves in the first place. Not only were my groups smaller and acceptable hunting groups, using the ones you sent me, but velocities were up by 75fps using the same loads I did with the bullets I bought. Second, here is a picture of one of the 165gr SS I bought from Midway on the left and one of the 165gr SS you sent me on the right. Seating depth, powder, brass were all the same so the residue in the grooves is the only culprit I can think of that was causing me the problems I was experiencing.
First bullet I bought on left - The bullet you sent me on right
Three shot group of 180gr SS using MRP moving 3193fps average out of a 24" barrel. Very good load.
Three shot group of 200gr 358Win 2636fps, I like these but going to buy 225gr SS because I can move them at 2550gps easy since I move a 225gr Accubond at 2550gps, that is enough velocity to get expansion with the SS. Plus my 358Win likes 225gr bullets much better than 200gr.
Four shot group 165gr SS moving 3226fps is good but I will use the 180gr SS for my big stuff and use my Sierra 165gr HPBT for deer.
Thank you for sending the 165gr bullets for me to try and for the 180gr SS bullets which I really like. Yours truly, Mike Price
