Pretty new to LRH, green as grass so please be gentle. Disclaimer: I'm definitely a statistic; didn't own a rifle pre-election. Now have two 270s, a 6.5x55 Tikka and a 6.5 Grendel AR. I reload for all of these rifles. I regret buying two 270's; one never gets used by the son I bought it for. It is a 1970s vintage model 700; the trigger is nice; I'm wondering about using it to start a custom build. I want a paper punching varmit shooting rifle out to 300, maybe 500yds. 1. What calibers would make the most sense with this action.... do I need to stick to certain cartridges if I want to minimize messing with the bolt etc. Are there particular calibers that will work/feed better in this action? Ones I've considered: 204 Ruger, 22-250, 6mm PPC, 6mm BR, 6.5x47 lapua 2. Is it possible to use the rifle's old stock for this build? 3. If I go ahead with a rebarrel, bedding, what would you guess I would have to spend for the job............ is it possible to ut $600-$750 into a job like this and have a more accurate rifle than a factory model? Thanks!
