1. Federal 210M – Listed for over 50% of the loads, this primer was clearly the most popular for super-accurate loads. It is Federal’s “match grade” version of its standard large rifle primer, the 210. (Sometimes refered to as Federal GM210M)
2. Winchester WLR – This is said to be the hottest non-magnum primer, and is hard enough to be used in semi-autos. (Sometimes refered to as Winchester LR 8 1/2)
3. CCI BR-2 – The “match” version of 200. This is also considered hard enough for use in semi-autos.

My old Number 3 Nozler Manual (1989)(David Petzal) recommended magnum primer for .270 Win....never tried that or heard about it since. "In almost all instances , you'll find better results with a magnum rifle primer". He did not specify what "better results" meant.

When you use magnum primers just back the load of a couple of grains cause they give ya a hotter ignition.
