so a buddy and I are reloading rounds for my Remmington 700 AAC.
we have the headspace dialed in correctly by blackening the bullet and chambering the round.. blah blah...

my issue is once we have the round pressed, it seems really tight in my rifle.
I dont recall manufactured being that bad.
we loaded it in my buddies old 308, it was still tight, but nearly as bad.
we are really green at this so I just want to make sure we have everything done correctly.
anyone have any ideas about why it would do this?
 
Is this brand new brass or once fired? if once fired have you full length resized it?

Once-fired brass fired in a different gun will not always chamber in another gun. I've found even Hornady Factory 168gr Amax is tough to chamber in my rifle yet my reloads with new brass chamber just fine.

As said already definitely read a few books before you start loading
 
The fired cases need to be lubed on the outside and pushed all the way into a full length sizing die until the shell holder hits the bottom of the die. Clean off lube and try the empty case in chamber. Should fit without resistance.

Watch you tube.
 
If you want the round to work both in your buddy's rifle and your rifle, you should cam over FL size the brass as suggested. Otherwise Check you OAL your bullet could be jammed, head spacing will be slightly different in both rifles. A thou or two will make a difference.
 
Sounds like you need to bump the shoulder back. If you're using a full length re-sizing die make sure you're using it as Ganderite and 308BAR described.
Check your re-sized brass against a factory round and see if the length to the shoulder and shoulder to neck are significantly different.

D!NK
 
Don't listen to ultimate monkey. Besides being incapable of offering useful information, he is just ignorant. Time for him to read some books on human interaction.

From your description it does sound like your dimensions are off on the case. Could be in a number of areas though and without posting more specs it will be hard to diagnose from our end. new brass vs once fired will also be distinctly different in your chamber.

I suggest you do some measuring on the tight cases. Overall length of the case, neck and shoulder. Using a blackened bullet in a case gives you an idea but it is far from accurate. Using the proper gear to measure bullet seating depth will give you much more accurate info.

Chambers can vary from gun to gun, so it may be tight in one and not the other.
 
How about trim length? Necks could be too long if the brass has been resized a bunch and could also explain why its tighter in a different rifle. Different chamber specs. Just a thought not yet mentioned.
 
Thanks for all the info guys.
the brass I have been using is once fired and I only put it into my buds rifle just to see if his was as tight as mine was which was very close.
but after reading a few posts online and from what you guys have said I'm going to definitely check the neck of my brass I had a suspicion that was the problem in the first place
