.22-250 Groove # and twist
I've searched for this and found some info on the twist rate I probably want but I have a question about the number of grooves. I was really looking into the Remington 700SPS Varmit in22-250 but the 1:14" twist just seems way too slow. I am not really interested in shooting 40gr. bullets 4000fps. I would really like to try the Berger 75gr. VLD with a listed BC of .447. I have read that some guns with a 14" twist "might" stabalize a 60gr. but I'm sure there is no way they would work with a long 75gr. VLD. At this point I think I'm going to go with a 26" heavy barrel with a 1:9" twist.
Now how many grooves? I read somewhere that the 3 groove barrels with fast twists can shred lighter bullets. I am really hoping to shoot the 55gr Ballistic Tips and the 75gr. VLD, the light and superfast bullets don't really interest me much.
So for 55-75 gr. bullets out of a .22-250, possibley a .22-250 Ackley, would you recomend a 3 or 5 groove 1:9" twist barrel? Or would you suggest something else?
