trouble chamberring rounds

[Swamp Hunter 38]

I loaded some 270 bullets for a friend and he said the he was having trouble chamberring . I found that the neck was hitting the lands smashing the edges but the bullet showed no no evidence of touching the lands. The oal on the case was correct so what is hapenning?

Need more information-

Is the brass you loaded from the same rifle?

Did you full length or partial full length resize?

Did you crimp the bullets?

Sounds like ya better double case length.

Is it a custom chamber (tight neck)?

Do you get the same effect with an empty case?

JD's right, more info needed.

Every rifle is slightly different, even the same make and model. One might have a tighter bore, a shorter throat length before the rifling, tighter chamber, and any other number of variables.

If the OAL cartridge length was okay and the bullets were not being rammed into the rifling, I can think of a couple of things that might be going on. I would try this.
.270 Winchester trim to length: 2.530
Take 4 unfired, unprimed cases. Even new cases will have rough edges and will not be very consistant in length. I trim all my new unfired brass to the specification called for that particular cartridge. After trimming I chamfer the inside and outside of the case neck to take the edges off. Usually only a little will be removed from the cases, but you will be surprised. It does square up the front of the case so that the bullet is released evenly all the way around the case. (just one little factor to assist in getting good accuracy) Seat 4 of the bullet you used for your friend in these dummy rounds that have no primer and no powder. Now take those four rounds and put them into your buddies .270 magazine and cycle them through the rifle. (Outside and at the range in a safe direction, I would also chamber a loaded round with the same or very similar weight and style of bullet to see how they feel when being chambered, and to check that nothing odd is happening with them and they chamber okay)

Next do this. Take four fired cases and resize them and then trim to 2.530" and chamfer the case neck inside and out to remove the burr left behind. Take four of the same bullets you just loaded and used in the above test rounds and seat them to the same depth as you had without changing that equation. Put them in the magazine and see how they feel. They should feel the same as the fresh factory brass you just used. If not, your die might not be set up properly and you aren't resizing the case enough for HIS chamber in HIS rifle. You might have to set the die so you resize the case just a tiny bit more than you are right now and have it set to full-length resize. It does not sound like this is what is happening though.

If I had to guess, it would be simply that his throat in his rifle is a little bit shorter, the cases might be a little too long and need a sliver trimmed off of them, or they have not been deburred or have rough edges on the case neck.

I hope this helps, and if you work through these steps I think you will find where the problem lies. Good luck. :wink:

Have you backed your seater die up so that it is not hitting the brass mouth and crimping the bullets? If the seater is set too low it will crimp too much and raise a ridge that is all but undetectable but will still keep the case from chambering.

I will check everything that was suggested. Thanks for the help! You guys are awsome!

I ask this only because it just happened to me. Is the die going all of the way down on the casing? I had a problem with my decapping rod too far down. It would not let me completely resize the case.

Not sure how far your bolt is closing but mine would go full length but would not rotate closed.

Is this 270 you reloaded for an autoloader? These require the use of small base dies from what I understand.

By the way I am not too far from you Gonzales area
