Will 115 gr. Barnes TSX bullets stabilize in a 1:10 twist 25/06 barrel?

The Barnes manual does not suggest you need a 1:9 or faster twist for a 115 gr TSX in their 25/06 data. I purchased some to try and it says on the box that they are for a 1:9 or faster twist. Has anyone tried them in a 1:10 barrel? Any help would be greatly appreciated. I can not get in touch with Barnes Bullets.

I haven't used that bullet but I have some experience with Barnes. Their bullets are nice, but their published reloading information is poor and often inaccurate. I worked up to their published max load in .308 with a 150 grain and got pressure signs half a grain of powder before. Less than a year later they had revised the max downwards by 0.7 grains.

Now to answer your question I plugged it into a calculator and it suggested marginal stability. I guess Barnes wanted it to stabilise at 1:10" but after a while realised it didn't do so consistently in all conditions. Always leave yourself a little buffer with their products - it's the safe thing to do.

I use that exact same bullet in my 257 WBY which has a 1:10 twist and it drives tacks (which tells me the bullet is well stabilized) - so I'm not sure it's twist alone that is the determining factor maybe - but I'm far from an expert.

I realize there are some differences in velocity/pressure between the two cartridges, and of course, I'm shooting from a 26" barrel - so maybe it's not a fair comparison.

EDIT .....

Played with the calculator on the above link and looks like the WBY (with higher velocity creates more stability). Seems like the lower the velocity the less stable the bullet is in a 1:10 twist.

This calculator shows me at the top end of "marginally stable" (or "almost optimal stability") but I can tell you, the bullets group amazingly well in my gun - so I have no concerns.

I would assume your 25-06 would follow the same logic.

Barnes Reloading Manual #4 states that they used a 10 inch twist for the testing of the 115 grain TSX, that would indicate to me that they will stabilize fine.

Thank you for the input. They may be just fine. I guess there is nothing to do but try them.

Im willing to bet they stabalize just fine

My ruger Hawkeye has a 1:10. I shoot 117 hornady sst's into 3/4 inch. .020 off the lands and half a grain higher or lower the group quickly resembles a spread of buckshot. The most definitive accuracy node I have ever seen.

100g Barnes were pretty good. I haven't tried the 115's. I do have a box of 115 bergers I've been meaning to test. They call for a 1:9 as well.
