I have just purchased a Tikka T3 Super Varmint in .243 and I am struggling to get it to group factory rounds.
The barrel is a 1 in 10 twist.
I tried Federal 100 grain and they were useless.
Tried winchester silvertip in 95 and they too were useless.
Tried Hornaday V-Max in 58 grain and they were slightly better at 1.5" groups.
The best I can get is about 1" with 5 shots at 100yds using Norma 78g BT.
Is this as good as I can hope or can any of you experts offer me any advice please???
Sounds about right to me. That is why most people on this site hand-load.
"If you love wealth more than liberty, the tranquility of servitude better than the animating contest of freedom, depart from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hand that feeds you. May your chains rest lightly upon you and may posterity forget that you were our countrymen."-- Samuel Adams
