[QUOTE="DMP25-06, post: 2240470, member: 27271"] I still run the "OldTimer" , .220 Swift , Ruger M77V , with a tang-safety . However , I had it re-barreled with a 1:8" twist barrel , 26" length that I had tapered to match the original Ruger varmint taper . I shoot 80gr. Hornady A-Max bullets at 3305 FPS , using H4350 powder , Fed 210 Match primers , in W/W brass . It is very accurate out to 1200 yards , but at 700 yards , it is EXTREMELY accurate . Using 16.9 oz. water bottles (which are 8"tall x 2.5" diameter) as targets at 700 yards , I have hit 10 in a row several times , and the visible splash that they make is impressive . I have only shot paper and steel with the 80gr. bullets . The original Ruger barrel was 26" with a 1:12" twist , that I ran 55gr. Nosler Ballistic Tip bullets at 3900 FPS , using IMR 4064 powder . It was 1/4 MOA at 100 yards . I had 1 verified 800 yard prairie dog kill and several at 600 yards . I have not yet tried a 55gr. bullet in the 8" twist barrel , because I don't know if they would hold together at 3900 FPS , which would generate 351,000 RPM's of rotational spin . [/QUOTE]
