    Default 30-06 rim bite trouble ????

    Went to the range today and had some trouble. The brass did not eject and has a bite mark on the rim. I alone shot 3 times for fear of makeing the trouble worse. This is a older woodsmaster auto 30-06. Check out the brass and tell me what you think?? Thank you

    The one still has the chunk. Not sure we're the other 2 chunks went. Kind of worried about this. Gun was on paper out the gate but not working just right yet.

    Looks like high pressure and maybe cheap brass. I'd try a better quality of ammunition.

    Ok. I was wondering that. It was just some cheap test ammo. I have a whole box of custom loads to test. Just was not sure if I was doing damage to the gun. I shot 3 total shots and than packed it up.

    what about the primer backing out? Same trouble as the bite??

    Years ago I owned 3 different Remington autos. I had a little trouble with extraction on one of the 30-06 guns when the chamber got a little "sticky". They must be kept very clean to function well. On the other hand I never had any pull the end off of the case like that. As others said try some different ammo and also clean the chamber. Those guns work well with good ammo and if you keep them clean.

    I'm not an expert by any means but we have a Remington pump 30-06 that is a B!T** to eject the brass if the casings are too long. We have to make extra sure we trim the cases for that gun. We reload all our own stuff. So we can shoot the same exact bullets out of 4 different 30-06's all others being bolt actions but with that gun being the only one this happens to. I'm wander if this is your problem. Cheep brass really stretches. So that's just my .02

    I am going to send your pic to my uncle who has been reloading for 40ish years. I'll let you know his thoughts.

    Not the brass. I would guess it's the bullet type you are shooting. My guess it's a heavier longer bearing surface bullet and your rifle's rifling can't handle it. Try shooting ammo in the 150grn and see what happens.

    Thanks for all the help. I just want to make sure I am not going to do damage to the gun. It is a older hand me down family gun. I hand it broke down and some new parts put on. But maybe it still needs a good cleaning and than try to shoot the custom loads. I stopped firing after the first few test shots. Was on paper from the start but called it a day after 3 rounds.

    Got 7 different custom rounds I never even got to try out yet. Looks like more range time. Oh no. Don't twist my arm.

    Lol nice! Hate going to the range! Lol. Have you personally shot this gun before? Any problems then? I just find it a little odd that factory bullets are doing that. I haven't heard from my uncle yet. He's on Alaska time... (Trying to get all yard stuff done before the freeze). Lol

    Not that I am a huge reloader, but check your over all length (oal) too. That's a pretty big ding in the rim.

    Hi all I spoke to my uncle and he was saying that he thinks that the gun is ejecting the bullet before the bullet is finished it's firing process. Head space is what he said he would check first. Goes along with what's been said on the overall cartridge length. With the high pressures it's swelling the case up so it's hard to pull out which accounts for the chunk out of the rim. He echos my thoughts that his is odd from factory loads. His thoughts on why it's odd is that factory loads are not typically even coming close on head space. And usually factories and not very hot. He just is just basing this off of the picture. He said to see if it's a head space issue put a cartridge in the chamber and close it. Then take the cartridge out and see if there is scratches on the edges of the bullet. If it's engaging the riflings it should leave marks.

    He also noted that auto loaders have a different charge min and max when hand loading as compared to bolts and pump and such rifles. Just an FYI.

    The proper way to check for head space is go/no go gauge. The other way (cheaper) is to put a piece of scotch tape on the base of the round and close the action. It shouldn't close as it's about .004" of an inch thicker. I do this with my go gauge when I chamber a new barrel. However, with brass it will give some so it might not be super accurate. I would close the action slowly or slower than usual and it shouldn't close. Of course do this at the range. :)

    If it doesn't close then you're good to go. Checking for rifle marks on the bullet isn't an accurate way to check as a lot of folks shoot with the bullet "jammed" but you shouldn't see rifle markings on factory ammo though. So use a permanent marker (black) and paint the bullet and close the action. If it's touching the rifling then your head space is tight.

    I doubt it's a head space issue though. My guess is it's a long bearing surface bullet. It makes sense since the dwell time when fired is much longer creating much more pressure. I would shoot 150grn factory ammo after you check your head space. :)

    Yes gage it if you have one. Was only trying to give a quick not scientific way to see. Like I said I'm not an expert by any stretch. I only load using my uncle's data. So easy a caveman can do it. (Me.... Redneck hillbilly).

    Did you guys notice on one brass the primer protruding too far? executive pressure?
    Also, they all sitting not uniform.
    Take some regular store bought ammo first, it might resolve your problem.
    Also, clean the chamber well.

    It is factory. Sorry. Should have said this to start. I have custom loads ready to go. But I wanted to get on paper with the cheap stuff. I stopped shooting after a had the trouble 3 times. Was not sure if I was going to hurt the gun.

    Looks like a gun problem, very valuable advise here.
    I'd start from cleaning the sh..t out of the chamber, make sure it is not stuck after the shot.
    It looks like the casing is stuck inside the chamber and the extractor rips off the rim. Easy to check.

    Head-spacing is also not out of the question.

    How do the case mouths look? If the casing was a tad long for your chamber, it could create extra neck tension, and increase pressure. That one primer is really out. The stiffer extraction could cause the rim issue you are seeing. Just brain-storming, I'm no master reloader. Let us know what you figure out.

    Thank you all for the help. I was kind of scared I was going to have a broken gun. Let me start with a little back story. This is a 742 woodsmaster. The gun is around 40 years old and a hand me down from my uncle in Texas. It has always been a good gun but was having a small issue when I got it.

    I looked all over for a good smith. The first guy told me that I need a new plastic gun and that mine was just a wall hanger. He was sure that the reason the bolt was sticking was due to age and over use. I couldn't believe my uncle would lie and give me a junk gun, so I keep looking. Next guy said he was too bizzy with black guns. I said no rush, just want it by deer season. When he asked when deer season was, I knew I was in the wrong shop. My next step was to email the gun smith school. Lucky for my the head instructor emailed and told me some good info. He said the gunsmiths that take his class have to work on the woodsmaster for a final exam. Any of his students would know what's going on. So I tracked one down here in town. He broke my gun down and did a sonic cleaning. He put new parts if needed and added a part that was missing. The jam at that time was due to the action bars. They are a set and have a curved bar to connect the two arms. If the bar brakes the arms will not function as a set and get of track. One side was getting stuck on the mag.the smith fixed everything and did 3 test fires. A ok good to go.

    fast forward to this weekend and I have the bite trouble on the first shot I take. Only the 4 round in the gun since it was made back to new. I add a little oil and try 2 more shots before giving up for fear of hurting my gun.

    Yesterday the smith took a look and we even checked the brass from his 3 test shots. All looked good. Gun is super clean still and head space is correct. He could only guess that the ammo was the trouble. For sum reason the gun is starting to pull the round while it is still under pressure. He thinks my new custom rounds will be ok. Told me to start with my light loads. Use only one at a time and try to see if the bolt will stay open after the shot and eject the round. So back to the range. The good new is he said that it will be dead on at 100 if it was a inch hi on 25. Can't wait to get her dialed in.

    Thank you agian for all the replys.
    I love it around here. Great group of friends.

    Awesome. Let us know how that goes. Glad you had it looked at again. I could only give you my very limited first hand knowledge.
