So im working on a rifle for my FIL. Its In older m70 pushfeed .270, thats spent its whole life on molokai. Salt air, little cleaning, and getting shot once or twice every week or two.
Lets just say life on the islands is hard on gun barrels.......This one would probably have been better as a smooth bore, then at least there wouldnt be cheeze graters shoved into the bullets rhe whole length.....
Thus they want a new tube installed.
Now with my minimal equipment my go to for barrels is a short chamber prefit. This time i was looking for the fastest way to get this gun turned around, so ordered a new oldstock .270 Colt Light rifle barrel off ebay.
Same threads and shank dia as the m70, but a longer shank which i shortened with my belt sander and a jig i made.
Got the whole thing finshed, reamed to depth, and coated in about a week....I managed to get all the parts and tools in at almost the same time lol.
got it to the range, bore sighted, and took a shot at a 20yd box, and missed low. Checked the brass and everything looked good....except for this
heres a shot of the cal markings on the barrel.
and the second shot
What happened as far as i can tell, is this was a .30-06 barrel that go miss marked .270.
I KNOW better than to use parts without checking them thuroughly, but in my rush to get this finished and home, i missed something as obvious as to big a hole in the tube. Had this gone the other way, this could have been significantly more eventful.
As it was it was I touched off a couple more rounds just to see where bullets would go.
and the answer is everywhere....
Ive got a short chambered barrel on order and this ones coming off.
Cant see it being usefull for anything else without a pile of material being removed, or chambering to a larger, longer cartridge, but ill keep it as a reminder to not be stupid and rush.
Now for the two or three month wait.....
