I have a Tikka T3 Light in 30-06 with a 1-11" twist. Any suggestions on what grain I should go with. I tried sighting it in with 180gr but I could not. It was walking all over the place. I had my friend try just to see if it was me. It was doing the same to him. Im guessing 180gr is to high.

Any suggestions?

Thanks

I have the same gun. I reload so I am using brass that is fire-formed to my chamber, plus measuring the powder as accurately as my needs merit. So far, my best 3 shot group @ 100 yards was about 1/2" using a Nosler 180 gr w/ Winchester brass (pre-shot and fire-formed) and W760 Powder. Looks like this (except it is 180 gr):

I had better luck with the longer, heavier bullets than the 165 and 150 gr variants. The 165 Nosler's are a close second, but still not as consistent. This is strange since this goes against the typical grain vs twist ideology. Usually, heavier bullets need a faster twist rate to stabilize heavier (or really longer) bullets....but in the case of my Tikka Lite 30-06, it's been the opposite.

I am trying out some new 178 gr Hornady A-MAX's out this weekend with Ramshot Big Game this weekend.....

Just remember this: Dont go by grains, but by length of the bullet. Typically, the longer the bullet, the faster the twist rate should be. I dont know if you are reloading, but this will be the only way you can get a customized load with fire-formed brass for your exact chamber, without breaking the bank.

Try 150 or 165, Pete
