Lapua 6.5 Creedmoor Brass Bag of 100

i have fired around 8000 6.5 creedmoor with lapua brass with small primer, all reloads with a stiller action. no problems of any kind. 15 reloads. best brass i have used. previous review should check size of his firing pin.

As stated above, Lapua is the pinnacle of brass production. I am using these necked up to .270 caliber wildcat. It’s nice to be able just to reach in a box of 100 cases and pull one out and know it’s close enough to identical from the others that it will have you cutting the previous bullet hole and you don’t even have to do anything to it unless you want to run the deburring too around the inside and outside of the case mouth (but always check it anyway…). Regarding the first and 2nd post, I once built a .22×47 Lapua that use small primers with Lapua 6.5x47L parent cases. I used a Pierce custom action with small firing pin and heavy firing pin spring. I had the same problem with pierced primers as reported above when I cranked the charge up. I tried CCI BR4, CCI 450, CCI 400, Remington 6 1/2, Remington 7 1/2, Winchester WSR, and Federal 205 with the same results. Then I talked to the smith that built the rifle and he told me it was likely due to the sharper firing pen with heavy spring as much as anything. This happened several times, but with no I’ll effects to that action. The smith warned that it would cause the firing pin to seize up if it happened repeatedly, so I decided to try something else. I switched primers to CCI No. 41 steel cased primers made for ARs that use heavy springs. Heavy springs are good because they reduce the chances of misfires from light primer strikes, and theoretically reduce the amount of time it takes to get a bullet out of the bore by milliseconds. Problem solved. Never pierced another one. I have used those same cases in a custom Savage build with “normal” firing pin and spring with NO issues on regular primers. The issue the 1st poster describes COULD be due to an overly heavy firing pin spring, if not the pin itself, or both. Should be an easy fix to swap the spring first, unless the pin is obviously very sharp (small diameter). If the pin is too sharp, you can dull it down quickly and increase the diameter slightly with a whetstone or Dremel with a medium grit sanding bit. Don’t leave it flat, though; shape it up by rounding it off. Be careful not to remove much metal or you’ll have the opposite problem – misfires (light primer strikes). There is an easy way to fix that, too, but it is beyond the scope of this discussion.
