Working on loads for my 7mm-08's. So far, H4350 has been spot-on with published load data. Usually my velocities in 22" barrels are 50-100 fps. behind published data, but not with H4350, and especially not with 139-grain SST's. They are always above published velocities.
Wanting to test heavier bullets, I opted to try some RL-19. Published velocities for RL-19 with heavier bullets is often the highest of any powder. I was expecting to approach 2700 fps. with the 160-grain Nosler Partitions and Accubonds I tested. However, it was not anywhere close. Published max load of RL-19 is 47.5 grains, and despite the data showing 2710 fps., my loads maxed out at only 2470.
The same bullet at a max load of H4350 was giving me 2580 fps., just like the Hodgdon data shows.
Anyone else experienced this with RL-19? Did I just get a bad can?
