Need help with a good load......
 

for my 270wsm. It's a Tikka T3 Lite. This is a fairly new gun with about 40 rounds through it. I've tryed the factory loads of 130gr Winchester Balistic Tips and the 140gr Accubonds. It does not seem to like the coated bullet. Never got a group to shoot better than an 1.5"
I've also tryed the Federal vital shok 130gr balistic tips and I got them down to an inch but I know this gun will shoot better than that. They crono at 3280fps. This gun has a 1.25lb trigger. Any help with factory or handloads with be graciously appreciated.
Thanks
