since I cant locate gm215m primer will gm210m work good for 7mm rem mag using retumbo powdergun)

Define "will it work"? Just kidding.

It will "work" as in set off the charge. Will it meet your accuracy goals, the only way to know is to try.

When I started loading my WSM I was using 215Ms, as soon as I switched to 210Ms ES, SD and accuracy improved dramatically.

Use safe loading techniques and go for it.

I was using the 215 in the 7 mag with retumbo and groups were no better than 1.5 MOA, i switched to the 210 and with a few minor adjustment i shot a .654 ctc group at 100 yards. Havent had any problems as of yet.
