After inspecting the brass from the use of PP 2000 MR, a few of them started showing the on set of case separation >. Initially I used S&B Match Primers and then tried BR2's and things got ugly. It shot great, but I didn't have that "warm and fuzzy feeling". So, I think the PP2000 MR was a bit too slow. I developed the following:
Powder: Varget
Primer: S&B
Brass: WW
Bullet: 225 SST
I tried the powder charges of 49 - 53 and all of them performed outstanding. If it wouldn't have been for the 25 mph cross wind and head wind, I'm sure they would've been worthy of pictures. However, each load seemed to put two in almost the same hole, then I'd get behind the wind and I'd toss one 3/4 inch directly left of the others. The good sign, everything was horizontal.... no vertical climb at all.
When I returned from the range, I inspected the shells. NO pressures issues and NO on-set of separation. I picked the charge that I felt confident with and began reloading the same shells. However, this time I did something different. I only partially sized the neck with the full length die. I double checked all the primer pockets for increases. Nothing. Went back to the range and checked MOA at distances from 100 - 500 yards with the same nasty wind.
I'm happy to report the load did well. It held horizontal all the way out to 500 yards with a 25 mph cross / head wind. Everything was MOA. The cool factor????? It only took 14 MOA from Zero to print a straight line of 3 shots 5 1/5 inches wide at 500 yards!!!! :D :D :D
More to follow. I'm now moving up to the 250 grain BTHP's.
