These are my results.
I understand the implications of using this powder. The following is for information only. .223 20.6 grains WC680 powder. I have a very large supply of it which is why I'm testing it. #7 1/2 Remington primer. 55 grain Hornady FMJ (bulk) bullet with crimp. Mixed military and commercial brand once or twice fired cases. Mixed brands of plastic and metal 5, 10, 20 and 30 round magazines. This is a light load but it is quite accurate. With three different rifles with 16 inch barrels and 1/7, 1/8 twist rates, 5 round groups about the size of 50 cent piece and some holes touching are the norm at 50 yards. Firing done over a rest with the identical red dot sights on all three rifles. Note that this load will occasionally not cycle the action in two of the rifles (one a carbine length and one a mid-length) with their stock buffers. The MForgery runs just fine with them and an H2 buffer. Can we say overgassed? No pressure signs at all. No popped primers and no rub marks on the base of the cases. No case stretching either. I check each case. I understand that this powder is on the hairy edge for .223 but it seems to be working for me. This post is a presentation of my results and not a recommendation to use this powder for reloading .223/5.56. Thanks. |
