I inherited a .220 swift "bullpup". It was my uncles favorite varmit gun who was a fabled long range shot with it. He passed away forty years ago and my aunt left it to me when she passed last year so there is no one left who knows about it.
I have been reading up on the caliber and specs and want to restock it and start using it.(I`m a lefty) it has a right hand stock with a thumb hole that I can`t shoot.
Anyway I`ve read shorter twist is better for accuracy but harder on the barrel. Can one just peer down the barrel and count the twists or is there a better way. I do not have it here with me but have been thinking about it for when I get back to it
