M-1 Garand

also, if you can find them.
winchester makes an excellent 147 gr fmj that works well and is usually a decent price in bulk.
it's also very close in profile to the mili fmj's i have found on occasion.
they crimp in the right place too.

I have two garands..I use 150 grain bullets, and don't worry to much about damaging either one.. the reason, is I purchased an adjustable gas plug..(gas plug)
This way, I adjust the plug so that the rifle does not cycle, work up the load, and then make adjustments so the rifle cycles. This way, you can use any powder you like to, along with any bullet weight you like also.
Of course, while making adjustments for cycling, you also have to look at the affect on accuracy. It may change.
If you go back to milsurp ammo, it may or may not cycle..as the pressures would be different.
The way I view it, is that it is cheap 'insurance'. (cheaper than replacing damaged parts, or a rifle..)
