i have custom and factory (22-250 tooley remington and 2 R93's) i would reccomend all of them. i have also had some factory rifles (model 70, t3 and prohunter) i wouldnt get any of them them again, although the t3 was not a bad rifle, just not as good as some. the model 70 was a big lump at the time, but with a new trigger it shot really well. the prohunter (RIP) i will not talk about, but will always remember.
only advice i can give is try before you buy, be prepared to sell and try and get one in a decent calibre!! if you look for good second hand your learning experience will not be as expensive as when you buy new.
