FWIW, a slightly faster powder may reduce some blast in the shorter M7 bbl, if that's an issue.
Re Reading the thread, I was thinking the same thing...but I know it will reduce the muzzle blast...
powders that are readily available....Either of the 4198s, RL 7, H 322 and AA 2015....
try 25 to 30 grains of any one of those...
If you are hunting 30/30 ranges, you can drop either 4198 down to 20 grains and they will duplicate a 30/30 for MV...same with RL 7.
I've spent a lot of time developing loads for kids to shoot over the last 10 to 12 years...
where I deer hunt it is 30/30 ranges, so I use these loads myself...with an appropriate bullet they will work all day long on a deer.. regardless of size...your 80 grain Barnes falls into that realm...
