I finally got around to picking up some 36gn varmint grenades for my 22-250, however Barnes data shows the Federal GM210M used, which I don't have on hand, nor have I ever used (also no store in town has any). My question is how comparable is the Winchester WLR or the CCI 200?
I just got through working a load up for my ar-15 using the 36 grain varmit grenade. It is 25.5 grains of x-terminator powder and cci 400 primers. With a lenght of 2.231". As far as primers goes. You can usually use one or the other but you might have to adjust the the powder charge to a different primer to make it work good. However some powders do not like to work with certain powders and bullet combos unless you play with the load a lot. Hope this helps. Pat
