That is exactly why I did not use H4895.

I was looking for something that would return around 2200 fps but wanted to use a powder that would mostly be consumed in the barrel.

I found a few reduced 300 gr loads on loaddata using RL7 that were running really slow.
I am not a paid subscriber so I could not see the charge, but QL said it would have been maybe a 70% fill ??

Figured at 94% fill I should not have any problems so I loaded them up.
I think its running at 45k or there abouts.

Its actually a nice shooting load at 56 gr of RL7.
