I have the older T3 in .223 and 1:8

I've found it seems to shoot everything I load for it sub 1". The first load I tried to just run it in shot 1/2" groups so didn't bother doing any more development. I shoot the 77s for longer ranges and forgot to reset the seating die when going back to 69s for bench. Still shot 2/3" groups.

I normally load to 2.265, which sounds in the same ballpark you are looking at.

In the three years I've had it I must have shot 300+ rounds at 100 yards at a target and probably only 1 outside of that inch group, and that was probably me.

I have replaced the trigger spring with the £10 one sold online, to lighten it further. And I've got a plastic sledge to allow singe loads, the bullets fit but for long range target I like to load one at a time. Is it still needed on the T3X as a mate with a .308 could just top load his?

I've always found as long as the powder is in the ball park its col that gives you accuracy. I will eventually be doing some load development for mine, but think I might shoot better than I can hold it!

Great rifle.
