My rifle is a bit of an oddity. I think it must have a slightly "loose" bore because it takes considerably more 4831 to get velocities that everyone else seems to get.
With 130g bullets, I have to go to 62g of H4831SC to get into that 3100fps range that everyone else seems to achieve with 2 to 3 grains less.
With 150 grainers, my load is 59g of H4831SC for about 2925 or a bit more. Most people seem to get those speeds with less powder.
The rifle or brass doesn't exhibit any indications of being pushed too hard, I just think its an idiosyncrasy of this gun. I am not complaining because its accurate and the loads I have worked up have been very effective on game.
For reasons above, I went to H4350 with the 130g bullets. I found I got higher speeds with comparable accuracy to 4831.
