On reading the thread about the "unexpected pressure" that developed in another campfire members rifle I checked my Dad's old Pre-64 Model 70 .270 that I inherited. This rifle has always shot OK and never had issues with factory ammo BUT the cases for it always had to be segregated from the other .270s in the family as it would barely chamber them. The rifle would also never take the loads like the famous 60 gr of H4831 and 130gr bullet load with out showing pressure signs. We used 56 grains and a Sierra 130 for a lot of years.
Since getting the rifle I haven't experimented with it too much, I just hunt with it occasionally for sentimental reasons and want to keep it in good shape in case my brother's grandson shows interest in it someday. I have shot some mild handloads assembled in new brass and have shot some factory ammo in it for zeroing and hunting. I tried the "bullet into the neck test" with a Hornaday 140s and found it wouldn't fit in 80 to 90% of the once fired cases.
Is outside neck turning all the cases to be used in the rifle to create more space in the chamber upon firing the best remedy? I don't plan on wearing out the barrel on this particular rifle so getting 100 cases prepped for it is all I will need. Thanks in advance for the information!
