Default Using M-80(7.62x51) bullets to reload for a Garand

Has anyone used 7.62x 51 M-80 147gr bullets to reload for the Garand?

I have a bunch of them I bought to reload for my FAL and would like to use them for the Garand as well. I know Widners is offering a M-2 style bullet now but I would like to stick to one and buy larger quantities at a savings.

My issue is that if I seat in the cannulure the COL is long by roughly .020 if I trim to 2.484 as my manuals call for.

Would it be better to trim the cases shorter in order to seat in the cannulure or seat below the cannulure with no real crimp? I know the 3 grain weight difference is negligible but will start over on my workups just to be safe.

Ignore the cannulure and seat to any OAL that works. At M2 load levels you don't need to start over. Some rifles esp. if they have significant barrel wear, need the increased contact area you get from flat base bullets. Good Shooting........

They will work, but are not as secure due to reduced area for case neck to "grab". Seat to the cannulure and crimp, using Lee die if possible. .020" is not enough to worry about.

"...Would it be better to trim the cases shorter..." No. Like ceresco says, ignore the cannelure. The difference in length between a 147 and 150(or a proper 152) is neglible.

Thanks folks, that's the way I was leaning but it's always good to have conformation.
