i have had a reliable remington varminter that i bought new for 23 years. it's in 243 and i would like to know if it is possible to make it an ackley improved with out removing the barrel ?? it has killed everything from deer, antelope, turkeies, fox, coyote, praire rats, etc.... so i have a hesitation of losing the mojo, so to speak,by pulling the barrel, rechambering and putting it back on, it shoots a ragged hole with 70gr b tips, and i use it for my coyote killing tourney's. also can a set of dies be reamed to ai instead of buying new ones ? now who can do it, and how much ?? and i do appologize to the smiths that contacted me about my 338 build, i traded it off to a friend who wants a 338 lapua. now i have another 06, to replace the one that went out to be made into a 280 ai.
