Which bullet for accuracy at 100 yards using 1 in 12 twist barrel?

Every .22 calber rifle I have or have had that shoots bullets in that weight range has been most accurate with Barts 52 flatbase. This includes .222, .223. And 22BRs.

 

Might want to try the 53 Nos Varm also.

 

Get the original or Ultra 52s?

 

This is my 26" Tikka barrel 12 twist , third test with 64 berger. (Now discontinued) but the 60 Berger would be similar.

 

Try the Sierra 60 grain flat back.
You might be pleasantly surprised.

 

a truly amazing bullet in my rifles has been the horn 50 zmax/ vmax. as in .2 at 100

 

My go to prairie dog bullet for my 223 ackley rifles is 40 gr vmax for the last 25 years. All of my barrels have been 12 twist Kreigers .The vmaxes are pretty accurate in my varmint rifles and really explode nicely on the dogs. My chronograph shows a little over 4000 fps out of the muzzle. Kills Them Dead !
