Hello,
I'm new on here and this is my first post. Started reloading 5.56/.223 during covid when it was difficult to get ammo so I could still shoot on a regular basis. I've always used Accurate 2230 and have found in between the minimum and maximum load to generally be most accurate and consistent. I recently purchased H335 and reloaded about 750 rounds. I made the novice mistake of reloading a ton of rounds without doing a small batch for testing (will not do that again) about one out of 10 rounds I have the primer popping out of the brass. I'm not using once fired brass, this is all new brass purchased. Here's what I'm reloading and the weapon being used.
- Geissele Super Duty 11.5" gun - 5.56 chamber
- New Winchester brass and brass head stamped VLC trimmed to 1.750"
- CCI 5.56 primers
- Sierra 69 gr and 77 gr bthp bullets with a very light crimp
- H335, 24.5 gr. For 69 gr bullet (Lyman 50th Edition recommendations is 22.9 - 25.5
For 77 gr bullets I'm using 24.2 gr (Lyman recommends 22.5 to 25 gr
Is this just too much powder and I need to cut back or is there something I can do to salvage 750 reloaded rounds? Not sure how NATO crimps their primer pockets but is there a commercially available tool to crimp primer pockets once the primer is pressed in?
Sorry for the long question but any help is greatly appreciated.
