Yet MD's "Handloads That Work" lists 36 gr. RL-15 as a great load with any 170 grain bullet.
".30 WCF: I still use the same load
here, partly because RL-15 is an
even better powder. A 170-grain
bullet and 34.0 grains gets 2,100 fps
out of most 20-inch carbine barrels
and can push 2,300 fps from 24-
inch rifle barrels. "
Went back and re-read the article and wanted to note your quote is correct. 34.0 grains with a 170 grain bullet,
NOT 36 as I had mis-remembered.
Went out last week with some bulk 150 gr. Remington RN bullets and 35.5 gr. of RL-15. First 4 shots went into a cloverleaf that measured exactly .408"! Of course, the next four shots went into about 1 1/2, but it sure is a "Holy S---!" moment watching that first bughole being created.
Am going to try Alliant's top load of 36.0 RL-15 with a 150 this weekend just to see what it chronographs. Even though this Marlin could take it, I'm pretty content to sticking with 34.0 RL-15 and 2200 fps which is a very mild load but still gives great accuracy.
