It works… I've shot everything down to a 40gr with decent / good accuracy, those things were screaming though! Hornady factory rounds and if my memory is correct they were moving at 3600fps out of the Lite barrel and 3675-3700fps out of the Varmint barrel…did not reach the 3800fps stated by Hornady in either gun, forsure it was because of the twist rate.
Currently I shoot the 55 & 60gr Nosler BT Spitzers and they are supper accurate for a varmint and target shooting. Shoots the factory Hornady 55gr Varmint Express V-max very well if you have the opportunity to buy them.
The 60gr Nosler is super accurate with 25.5grs of Varget in both my Lite and Varmint 223 T3's…just a little better BC and drop than the 55's…One of our favourite things to do at the hunting camp is shooting clay skeet targets at 400-500yrds, I love beating the 7mm & 30cal guys with my little 223 pee shooter…! Makes for some good talk and laughs over beers after. Its also a super coyote load, these little pills absolutely hammer them!
Worth a look if you are reloading, even IMR 4166 is the same charge +/- a bit will get you there as well.
Check out the target picture using 55gr Noslers…perfect shooting conditions at the range that day. 200 yrd load testing. Notice that my T3 Lite almost shot 2 “identical” 5 shot groups at 200 yrds with a proper cool down.
Cold bore shots are the furthest ones to the left on both groups. The remaining 4 rounds in each group are almost carbon copies…its amazing when you get a load that performs like that.
