Switched powder to IMR 8208 XBR, switched to an RCBS seating die.. Might have something tomorrow.. I believe now I was all wrong, yes again, about my firing pin retainer, I was WAY over crimping, and mashing my cases down where the bulge wouldn't fit n the chamber.. If this keeps up I will be the most humble shooter, not to mention the laughing stock of the sport. Switching from Lake City Brass to 223 Federal with the idea that the 223 may have thinner walls and slightly higher case capacity.. Max charge of 27 grains of powder was compressing the powder with the 80gran GMX.. Trust me you don't own the market on mistakes. We all make them. Greg PS: Back that crimp off completely and shoot a few. You may well thank me.

Here is a question about powder compression. How much is acceptable? I am loading it in federal 223 cases, with CC No 41 primers. Using IMR 8208 XBR and 80gr GMX Bullets. Beginning load of 24gr, top of 27. I am at 26.8 and am going to stop here. Ever since 25.5 the bullet is compressing powder. I know the gmx is a bit long (It is the same bullet corbon uses), but how much can I compress the powder? Safely? my rifle is made of aluminum foil after all..

With 8208 or with most all extruded powder, If its not pushing the bullet out of the case you are good to go. On the other hand DO NOT compress ball powder. With ball you will get erratic burn and your pressure will be all over the chart.

I also have some Accurate LT-32 which is a fine extruded with a faster burn rate.. on the par of IMR 4198 or RL-7. Would that be a better choice, it would offer a decreased powder load? What powders are y'all using?
