SAWING OFF A RIFLE BARREL, 3/28/2017
Most Savage barrels in 22-250 have a 12” twist. My most accurate cast .22 bullet is a modified Lyman 225646 that is ~.692” long and requires an 11” twist or faster. I had a 223 Rem Savage barrel with a 9” twist, 22” long, and Ken Campbell re-chambered it to 22-250. It shot almost as accurately as my other 22-250 barrels. I wanted to try the barrel on a Savage Striker pistol, so I sawed it off with a normal hacksaw to ~ 16.5” , filed the muzzle about flat, and chamfered the bore a little with an RCBS chamfer tool.
On the Striker action the barrel shot the 225646M into 100 yard 5 shot groups that averaged 1.480” for three sets of five 5-shot groups-15 groups. These with 7.5 gr. Titegroup.
With jacketed bullets, 5-shot 100 yard groups, 7.5 Titegroup, “:
Nosler 40 gr. Varmageddon .55, .9, 1.15; Avg. .867
Hornady 55 gr. V Max, .975, 1.15, .875; Avg. 1.0
Hornady 60 gr. SP,.7, 1.2; Avg. .95
Hornady 68 gr. BTHP, .9, 1.05; Avg. .975 These were tipping slightly
The jacketed bullet average for 4 bullets 10 groups 50 shots was .945”
