well mind you I am working alot of military once fired and all got a FL sizing. The primer pockets "tension" varied some but upon looking with a 10 power loupe at the ones I loaded above 21.5, a gold ring showed at the neck/shoulder point on the loads , that AND a circular mark running all the...
Steve4102, I took a look at all my Mil. once fired 223 brass, even the stuff I have'nt loaded and found your flow marks on some of the bases. FC,Winchester, RP,most LC and WCC look ok but Nato WCC and a few others show ejector pocket marks.. 3115 fps seems to be a common speed for a 16" barrel.
Does anyone have a link to a 223/55 grain/barrel length chart ? If 16" can't safly push a bal. tip to 3240 then I'll take the 16" load and just componsate. You know having a short barrel leads to compensation anyhow:evil:Thanks.
Got the chrony and @ last loading with IMR 4198 got 21.5 = 2936,22.0= 3063, 22.3=3115. 16" match stainless. I was caught between H 335 and IMR 4198. Tried my 308's IMR 4064 @ 25 grains but it was'nt even close. I want to match the spec info on the factory 223 but can't find what length barrel...
BDS mentioned somthing about military crimps on the primers and thats my point.Getting a crimp remover for my 223, 308 and 50 solved any resistance issues, plus I put a slight bevel on the mouth of the primer pockets. I also use the Lee hand prime, lost the large priming pin for the old round...
Being an FCSA member is great but maybe I can get 223 load info here. I bought a Fulton Armory lower receiver and an M.&A. upper kit with a 16" barrel which shoots great. I then bought a Nikon M-223 with the BDC reticle which is set for a 55 grain Bal. tip @ 3240 FPS. So far the only powder to...
