I started at Hornady load for 90gr GMX at 2700 fps all are with LR powder, 24" barrel , CZ527 rifle
2700 - 28.4gr powder
2800 - 29.5gr
2850 - 30.0gr
2900 - 30.6gr
2950 - 31.1gr
3000 - 31.7
out of Hornady reloading app.
What I got
2700- was 2885,2899, 2878
2800- was 3117,2963, 3017
2850- was 3045,3014 and one round wouldn't chamber ( may have missed it when I sized the last time) checking
2900- was 3033, 3141
2950- was 3123
and
3000- was 3150
The 3050 load filled the brass case so I did not try to compress.
The Factory cases ran 2728,2758, 2742
Rounds below are starting with 2700 to far right in green case working to left with highest at left case wall and the 3000 load at the top of picture.
Factory loads are black case
Take aways from my first reloading experience
1. I am going to check my electronic scale against my manual scale not sure of it.
2. My Magnetospeed loosened after several shots and I didn't catch it soon enough so could have been the strange spreads I got on some.
Below are pictures of the primers
