Bulging case necks with 107, 108, 112 grainers in 6BRA

So I'm new to the 6BRA ( not new to wildcats), and am having a hell of a time with it. Any bullet I heavier than the 95 grain Berger VLD Target, bulges the case necks to the point where the round will not chamber. Barrel specs are as follows..... Douglas 6BRA. 1-8 twist, .272 neck, freebore unknown( I bought the barrel lightly used, and the fellow couldn't remember). Savage small shank barrel. When heavier bullets are seated to .015 off the lands case necks bulge to .269. is this common, if so would neck turning be the solution? Or would a smaller bushing for my L.E Wilson fls die be a better solution? I'm currently running the .267 bushing. Any input is greatly appreciated

Are the necks turned clear to the neck shoulderr junction and do they have the proper wall thickness the whole length of the neck?
 
With a .272 necked chamber that .279 will not chamber period. No, that is not a common thing. Seems strange that you are getting bulged necks out to that degree. It does not appear turning the necks or a smaller bushing would make that much difference. Maybe some double checking the chamber neck diameter would get an answer.

^^^ Check chamber neck is the next step for sure..
 
I'm just as confused as you all are.... I've never had any experiences like this before.... And I've had some pretty extreme wildcats.... Like a .243 JRP(270 Ackley improved, necked down to .243).
