kneelingatlas Posted March 14, 2016 Share Posted March 14, 2016 Those are some big holes, you're going to have to get used to people being shocked by your charge weight Here's a picture I pulled from Google: I wouldn't be surprised if your primers looked somewhere between center and right. I like using SPP because they don't hide the pressure signs and seal the primer pocket better, protecting your beech face from erosion. Link to comment Share on other sites More sharing options...
evilbeef54 Posted March 14, 2016 Author Share Posted March 14, 2016 OK so here are some casings from the other day is that an overpressure sign on the right primer, is that the flattening? Sent from my SM-G930V using Tapatalk Link to comment Share on other sites More sharing options...
kneelingatlas Posted March 14, 2016 Share Posted March 14, 2016 Are they all the same load? Do remember you're using the softest primers available, and none of those are flowing into the primer hole yet. I think you can give it some more Link to comment Share on other sites More sharing options...
evilbeef54 Posted March 15, 2016 Author Share Posted March 15, 2016 No those 3 were not the same load 8.5-9.0 gr 9 on the right. Thanks for your help Sent from my SM-G930V using Tapatalk Link to comment Share on other sites More sharing options...
Chillywig Posted March 17, 2016 Share Posted March 17, 2016 (edited) Ironically I just started looking for some loading info using silhouette in the super and came across this post. Here is what I did based on others info and chronoed todaySTI Trubor Zero 121 JHP 1.282 OAL Federal mag primersGR HIGH LOW AVG ES SD PF8.0 1341 1326 1333 15 7 1618.3 1368 1329 1350 39 15 1638.5 1404 1373 1392 31 12 168I loaded mixed head stamp brass I had fired thru the same gun. I did seem to notice the brass rounds had slightly higher velocities compared to nickel cases. Looking at the brass the brass seems to swell a little more than the nickel possibly sealing the chamber better or releasing the bullet easier. At 8.5 grains I was starting to see some decent flattening of the primers but no wear near anything that would cause me concern.I am not sure why I loaded these so long. I think I will set them in ~.005 and re try the 8.5 load. Edited March 17, 2016 by Chillywig Link to comment Share on other sites More sharing options...
Chillywig Posted March 20, 2016 Share Posted March 20, 2016 So I seated the loads in a little deeper. OAL is 1.270 and if anything it slowed them down a bit. 165 PF is the best I saw. I also droped 10 power charges into the scale and am loading 8.44grs. Im gonna bump it up again but will be a while before I can chrono again.

BeerBaron Posted March 20, 2016 Share Posted March 20, 2016 Are the 4 'holes' on the barrel island drilled through? It could just be the pic but it didn't look like they go all the way through. Link to comment Share on other sites More sharing options...
