A friend of mine was unable to chamber several full length re-sized rounds in his BSA. After much messing about, he mic'd the case heads on some other rounds which he was able to chamber. Most of my manuals indicate measurement at the '06 case head as .470". The rifle in question won't accept anything with a case head in excess of .467". His options seem to be: 1. factory ammo, 2. using only brass which has been fired in that rifle., or 3. special order "undersized" dies.
Any other thoughts? If the special order dies are the route to go, can the dies be ordered from RCBS, and do they produce a "standard" undersized die, or do they need his chamber measurement to make up the dies?
 
definitely only use brass that has been fired in that chamber. You will most likely find all your problems go away, with a partial FL sized case from that gun.
 
X2 neck size once only fired brass from that rifle or stick to factory. A small base sizer die may fix the problems as it brings the brass back to the minimum tolerances for semi's and auto loaders, if you can borrow one it may be worth the try.

Once fired, neck sized ammo is likley going to be VERY accurate in that rifle.
I wouldn't go near it with small based dies, OR a standard reamer!:eek:
What you have is a chamber that many shooters pay big bucks for , and if you are using properly sized ammo or factory ammo, there will be no issues of chambering it.
I know many fellas think that neck sizing and tight chambers have no place in the hunting world, but the truth is unless you are shooting something like a Lee Enfield chamber, most ammo won't go in if it has a bit of dirt or other grunge on it!

Get you OAL right, and you will likely have a laser beam on yopur hands!:D
