Garand Reloading, Too fat burning powder???

[noonanda]

I know the M-1 garand is limited to powders faster burning than IMR 4064, but is there powders too fast burning for the garand, such as reloader 7 or IMR4198??? any help would be appreciated

Noonanda: My guess is that yes, some powders will be too fast for a Garand. I recently purchased one of those newly manufactured Springfield Armory Garands. (Works perfectly - an awesome rifle.) As yet, I'm using el-cheapo corrosive Korean ammo in it and so haven't had to reload for it. I base my yes answer on knowing that the Garand (like all semi-auto's) uses timing to function properly. If everything in the action moves too slowly, you've got problems. Same thing if things are moving a bit too briskly. Having beaten around the bush, let me refer you to:

This is the link for the reloading section for a forum that seems to be a gathering place for a lot of Garandaholics. Do a search here and you should find your answer. Good luck.

Conventional wisdom from as far back as the '50s, I think, brackets the fast end as IMR 3031. That one's okay, don't go faster unless you're willing to get slower velocities with safe loads. High port pressure is NOT a problem with "too-fast" powders, but I've never heard/read/seen/experienced any firsthand reports of port pressure being too low.

Well, my lead-bullet loads with IMR 4759 didn't cycle, but we didn't expect them to. Those were way-light anyway.

I've always stuck with 4895 for the Garand, which is what was used in the military loads.

I've always considered the two ends for burn rates for powder on the Garand to be IMR4064 on one end and IMR4895 on the other. If you have access to a Sierra manual they have a good section in there on reloading for gas guns.
