.223 55 grain fmj federals,short brass?

[wtnhunt]

Anyone else here reloading for .223 that has run into issues with federal once fired brass coming up below trim length of 1.750? Have probably a couple hundred pieces that are between 1.740 and 1.745 that I have resized and cleaned but not loaded, those are after resizing lengths. I had planned on loading some varmageddon tipped rounds for hunting, but not so sure I want those kind of variances and potential accuracy issues in rounds I intend to kill yotes or other vermin with. Thought it was kind of odd to have that much short so pulled a handful of unfired rounds out of a box and some measured as short as 1.735, and some were close to 1.740 but not one I measured was to 1.750 minimum.

Having fired a lot of the factory loaded shorts already, I guess they are safe? How much is a hundredth in brass gonna effect mid range(under 200 yards) accuracy if I reload these? Or should I load them up with some sp's and they be used primarily for plinking? Read somewhere online that someone suggested trashing all brass under 1.750, would that mean the factory loaded stuff @ 1.735 is not safe?

load a handful up and see what the results are for accuracy.

if Factory are 1735, I doubt they are unsafe.

The .223 headspaces on the shoulder So if you ran them through a properly adjusted resizing die, your missing length is just in the neck. They'll grow out with successive firings. The accuracy variation from the tiny differences in neck tension will be statistically insignificant unless you're intending to do some 1000 yard competition with your rifle. Load em and shoot em. Or better yet............box up all the short ones and send them to me !!!

that's what I was wondering about. how the differences in neck lengths/grip on the bullet would effect accuracy round to round.

That is what I was hoping to hear. No 1000 rd matches, just some crows, beaver, and yotes mostly inside 200. Thanks for the replies. Will do some testing when we get some cooler weather, hopefully in the next couple weeks.

lol, think I may wanna hang on to them. Bought the "cheap" federal $38 per 100 rds stuff when the .223 ammo and brass was through the roof or near impossible to find with intentions of using the brass. Think I have another 6 or so boxes of those federal bulk packs around here somewhere. Have premium bullets and powder, hopefully this brass will stretch out to in spec with this next firing.
