.220 Swift using 80 gr. A-Max
I am considering re-barreling my Ruger 77V, .220 Swift , 1:14" twist , to a new Shilen 4 groove Ratchet-Rifled , 1:8" twist barrel in .220 Swift , in 26" or 27" length .
My intention is to shoot 80 gr. A-Max bullets , to have higher B.C. , allowing me to shoot accurately out to 1000 yards . I hope to be able to get 3200 f.p.s. or faster velocity .
Hornady customer service told me that the A-Max bullet would easily handle 3700 f.p.s out of a 1:7" twist barrel .
Do any of you , LRH members , have any experience or knowledge with a fast-twist barrel in .220 Swift , or .22-250 , using the longer , heavier .224 bullets ?
I am open to suggestions on load-data , or , constructive criticism of my choice of the .220 Swift . My main reason for this cartridge is that I have 1000 rounds of brass in .220 Swift .
Thank You ,
