I had a 300 wsm built a few months ago from a Tikka action. Basically just spun a Benchmark barrel in 1-9.5 twist on to shoot 200-212 bullets, so nothing extensive.
When I saw where reloading components were heading last summer I bought enough components to last a while for this rifle. I found 120 once fired Nosler brass that are a little older, not sure of age (stamped Nosler). Then I bought 50 pieces of new Norma brass and 50 pieces of new Nosler brass (stamped NOS).
During load development I just used the new Norma brass. Had a pretty good load worked up with 65.5 gr H4831sc, new Norma brass, CCI 250, and 212 eld-x. Seated .09” off the lands was very promising.
I ran out of new Norma brass, so to finalize the last tweaks, I loaded some of the new Nosler brass with the same charge and varied the seating depths in .005 increments to see if I could find a magic combo.
While shooting the new Nosler brass, I was getting sticky bolt lift and recoil was noticeable. Quick chrono reading gave me 2805 FPS at 65.5 gr of powder, which is a little faster than what I was seeing with the new Norma brass. Groups went to hell as well and did not match up with what I had seen using Norma brass, plus I was obviously flirting with too much pressure.
Decided to weigh the new Nosler brass and they all weighed around 261 grains. Very consistent, as 10 cases were all within .4 grains. The new Norma brass weighed 247 grains average, and the old Nosler brass was in the same range. Both the old Nosler and new Norma brass are within 3-4 grains of each other.
Thinking the old rumor that Norma makes Nosler brass was true, but that is no longer the case.
While I think the new Nosler brass is extremely consistent, it is not matching up with the old Nosler and new Norma brass. Since I have 170 cases of old Nosler and new Norma brass, might have to get rid of the new Nosler brass in order to keep things consistent. I’m also excited to see what ADG comes up with later this year.
Just some data for those reloading the 300 wsm. Yes, I was dumb to assume they were the same, so my mistake might help someone down the road.
