While thumbing thru Cabela's Fall catalog, I noticed in the Barnes bullets they have a small box saying what twist certain bullets[TSX] need; example: .25cal,115 needs a twist of 1:9" or faster. Another is: .270/150 needs a twist of 1:9.5" Hmmm!
I know my Ruger MK2 in 25-06 has a twist of 1:10", but seems to shoot the 115TSX's fine. I do not know what the twist on my Sako Finnbear in 270 is, but it shoots the TSX 150 FB really well.
I've shot both at paper at 100,200 and 300 yards, and never saw any "tumbling". Should this be a concern, or what?
Any info on this would be greatly appreciated. Thanks.
