41 Rem Mag
Member
Hope someone has some ideas, I recently picked up a new Ruger Blackhawk in 327 Fed Mag. it is stainless and has a 5 1/2" barrel. After shooting it several times I noticed some of the primers were pierced and had powder residue on the primer around the firing pin indent. I am shooting a XTP 100 grain bullet over 10.8 grains of 2400, this is middle of the range for 2400 powder, 10.0 is the starting load and 11.5 is max. Not all of the primers are pierced, most are not, guessing 7 or 8 out of 100. The primers I was using are CCI and I have changed to Winchester small pistol mag primers, will see if that changes anything. I also have a GP100 in 327 mag and have not noticed it doing the same. The Blackhawk was new and the firing pin seems to be smooth and I can not see anything unusual. I will say, overall I was a little disappointed with the quality of the Blackhawk, just little things like fit and finish were not what I had expected from Ruger. Thanks Greg
