[QUOTE="liltank, post: 445985, member: 13275"] Primers are like powder, each has their own burn rate. The Benchrest primers like BR2 and Federal Match are better metered and are more consistent. I have played with Federal, Remington (don't like them, have had miss fires with old batches), CCI, and Wolf. Wolf and Federal have been the best primers for me to date for my 300 WSM and 308 Winny. Some like to use mag primers for ball powders because it has a different compaction compared to extruded powders and need a little more fire. On the other hand when reading about Palma shooting, some prefer a more mild primer to create lower pressure curves. I have noticed if you get a load that has potential, but with an occasional flier, a primer change sometimes will pull that flier in. Like 300WSMMAD stated, I have seen group shrink and get larger with identical loads and just changing primers. I have found that larger charges like the hotter primers (mag primers, in long bodied casings i.e.:Belted mags, RUM's, Lapua Mags), but in the instance of short mags the regular large rifle usually yields better results. I did try some mag powder in my .308 (RL17, Federal 210's) just playing around. The large rifle did okay, but my more accurate loads came when I switch to Federal 215's which are magnum primers. Powder burn rate definitely helps to determine the primer usage. Hope this helps, Tank [/QUOTE]
