I would like to build the gun on a blueprinted Rem. 600 as I happened to have an extra one laying around. Does this action have good accuracy potential and what caliber would you guys suggest for this SA? I was thinking 260, 250AI, or maybe even a 308. How about a 22/250 with a 1:10 or 1:8 twist?
My first choice would be a 22/250 or a 223 WSSM because of velocity and distance. The wind is
the only downside to light weight bullets. but they will do the job with almost no recoil. The best twist rate
would be 1 in 12 to 1 in 14 for the 22/250 depending on bullet weight you intend to use
and 1 in 14 to 1 in 15 for the 223 WSSM. The faster twist in these High velocity 22s is hard on
bullets so I don't recommend them personally.
I have a 223 WSSM with a 1 in 15 twist and have been reduced to the 40 grain ballistic tip (Designed specifically
for High velocity 22s) because all other bullets are failing at the velocity that I am able to reach because of over
rotation and jacket shedding. To date I have exceeded 4600 ft/sec with these bullets with no failures.
I tried a 1 in 10 twist on a 220 swift and had to hold the velocity at or below 4,000 ft/sec.
Wind is always an issue with the 22 cals and even the biggest bullets have trouble with it.
So with the drop at distance of the heaviest bullets,I chose to go with 35 to 55 grain bullets for
speed and trajectory. They also help you see the hit better. (Half the fun of it).
The old 220 Swift would also be a good choice.
Just my recommendation based on years of varmint hunting.
