Looks like Tikka is now making 243 with an 8 twist barrel. I’m sure these would shoot best with 90 to 105 grain bullets but was wondering if anyone has tried shooting lighter 58-70 grains out of them. Seems like tikka usually has a long throat for their chambers. Wonder if they increased the length of throat when they changed the twist? Hopefully these new ones work the way the 243 was designed to shoot light bullets for varmints and heavier ones for deer.

BE Great ! if they would go to a 1-8 twist for the 22-250 ! I would buy one then . RJ

I believe there was a custom run of 8 twist 22-250 in lite configuration done by Tikka for some customer stateside. I'd grab one for sure if they ever did another.
 
Not meaning to be critical here, but I'm wondering why one would want the 1:8 twist in a .243. The usual twist with this cartridge is 1:10, and that will easily stabilize pretty much all of the heavier hunting bullets--100, 105 gr. Seems to me that the lighter .243 bullets--60-70-gr. preferred for varmints and small game (where maximal accuracy is needed)--would be over-stabilized with the 1:8 twist. I believe that a few .243 target rifles have the 1:12 twist. My Wichita Classic has this slower twist which imparts the ideal "just-stabilized" condition to 68 and 70 grainers.

110 and heavier bullets, at a guess. - dan

Maybe the combination of some areas in Europe with minimum 100gr bullet for deer and lead free. Sales of 243 going back and 6.5CM as min being the easier way to stay within the law. I have had 243's with 1/8 in the past and would prefer one again over the 1/10. For longer shots the 243 lacks power with lower bc bullets. I also have a 1/8 22-250 which is fantastic with 75gr ELDM on longer range fox.

Guess to catch on the new trend to use heavy for caliber high bc bullets. I’m sure the 8 twist will still shoot light bullets good as long as the throat isn’t excessively long.
 
My remington 9 and one eighth twist wouldn't stabilize 105 grain bullets in anything below summer temps. I think 1 and 10 is too slow as an all round application. I have 8 twist 243 that shoots 68 grain well
