    Hopefully reloaders can help me with this. I wasn't sure if this was the right place to post this question.

    I own a few different .223 rifles but most are ARs. I was looking for some good ammo to settle in on that would cover all rifles. to make a long story short, I ended up buying 1000 rounds of HSM 55 gr HPBT (Gameking).

    Here is the problem. I went to the range today and had a couple rounds fail to feed, and in the process it shoved the bullet almost all the way to the neck of the brass. I took out the last dozen or so left in the box and could see that some of the rounds were visibly longer than others in the same box.

    there was a gentleman there who claimed to be an expert on ARs from 14 years in the military that told me hollow point ammo won't work in an AR but I have another AR that shoots 75 gr HPs all day long without an issue so I found it hard to swallow that one unless it is specific to that gun somehow.

    so, can I setup a press to an exceptable OAL and use it to make all the bullets the same length and will that fix the issue? Or do I need to do something different and give up on HPs in this rifle? I will be a while shooting 1000 rounds in my bolt gun.

    I should note that the AR I am using works flawless with all the SP and FMJ rounds I have used in it.

    I use HP bullets in my AR15A1 (1:9, 20").

    Sounds like your ammo is nose diving while being fed.
    So either there's not enough neck tension (allowing the bullet to setback too easily) or it may be an issue with the magazine.
    Take a finished round & see if you can push the projectile into the case.
    If you can, there's your answer.


    Have you tried HP loads in different magazines?

    Semi auto's slam the rounds pretty hard in feeding. This is one of the reasons military ammo uses a heavy crimp to help prevent jamming and bullet set back. This generally isn't a problem with a bolt gun or other more gently feed rifles.

    Good magazines are probably the most important item in ammo feeding properly. If you have magazines with the "level feed" followers the cartridge stays level and feeds out of the magazine properly without diving or releasing early. Level Feed followers can be easily and inexpensively retrofitted in older or cheaper mags that didn't come with them.

    thanks for taking the time to reply. I will take it out and try a couple different mags to see if the one I was using was the problem. however all my mags are old Colt 20 rnd mags. I do have a couple pmags I have never used. thanks again!
