[QUOTE="Starlite, post: 1934166, member: 112246"] This has been an awesome discussion. I’ve learned so many different things WRT primers today (and I thought I’d learned everything thru my readings and testing). One thing that I and others have come to realize is that unless you test. Test. Test and then test some more you’ll never really know what will meet your expectations; and satisfy your particular needs. That’s really y-i test so many different combinations. I, like many of you am chasing that unicorn of a load. If I were to make one macro statement about primers it would be this: 1.Generally within the same brands; magnum primers Will increase velocity ~ 50FPS over non magnum primers. 2. Federal primers are more reliable to ignite on first strike. 3. CCI BR2/4 seem to be most consistent lot to lot. 4. Don’t bottom out Remington primers (mainly 6-1/2 & 9-1/2) in the Primer pocket unless your using a stronger after market firing pin spring. In my experience you’ll have an increase in misfires. Especially with federal brass. Finally I’ll offer my opinion. Only load magnum primers for hunting. Winchester for LRP and CCI 450 for SRP. I use these because they can be seated deep; bottomed out while still allowing for good consistent strikes. just my 2c. One last point. My results are primarily from a Sako finnlight 6.5CM. A bergara B-14 HMR In 6.5CM. A Savage axis .223Rem A Remington 700 VLS .223rem. A Savage axis in .308win and A Savage axis II .270win [/QUOTE]
