270 Winchester w/Barnes 110 grain TTSX

[bobcat]

I'm thinking about loading up some of these light Barnes bullets for my 270. Curious if anyone has tried them?

Normally I use H4831 but I think I'm going to pick up some Ramshot Hunter and try the load that Barnes has listed in their data. This would mostly be used for antelope in Wyoming, but possibly deer too. I most likely will never shoot further than 400 yards.

Barnes data shows 65.7 grains of Hunter for a muzzle velocity of 3500 feet per second. I realize the BC is really low with this bullet but it still should shoot pretty darn flat out to 400 yards.

And the best thing of all is that recoil should be very low, hopefully so light that I'll be able to see the reaction of the animal through the scope when they're hit. (or not hit)

My main advice is load them fast for reliable performance.  Last bear fell to a 150 out of my 270. Your speeds should be plenty to get them to expand.

Trading BC for speed isn't a bad thing especially 400 and in.

Found it, needed more speed...dead bear regarless.

I think expansion won't be a problem, even if my muzzle velocity is only 3400 fps. The issue will probably be trying to get them to shoot as accurately as my 140 grain Berger VLD's. If I can't get the same accuracy, I won't use them.

I've shot that bullet out of a 270 WSM with excellent accuracy and fine results on pronghorns.

Loaded a bunch up for my 243 wssm with different powders and weight loads. Just need time to get out and shoot over my chrono.

[Bob33]

My 270 WSM shot it well.

Bob33- Wow! Nice group, that's a factory load? Do you notice a significant decrease in recoil with that bullet compared to 130's or 140's?

What I've read about the (T)TSX bullets is that they work best at impact velocities of 2800fps and above (with small bore calibers at least - medium and large bores are different).  Below that speed and they require heavy bone on the way in to expand desirably on the way through the vitals.  Under IIRC 2200fps the small more Barnes don't reliably expand even with hitting heavy bone.

So, what ever range you drop below 2800fps is probably a good cutoff for hunting shots.  I don't have a ballistics calculator handy, but I'd guess that if you launch them at 3400fps you'll be good to around 300 yards if that is your chosen cutoff.

honestly if your 140 s bergers shoot good id stick with them . I'm not impressed with the tsx or the ttsx performance on light skinned animals . if your shooting for pelts then maybe .

Check out the Hammer Bullets. I've played with two of their 338 offerings and I'm switching over to these instead of the Barnes for my hunting loads. They're easier to tune for good accuracy, have a better BC than a Barnes and in my testing they expand more consistently.

Those Hammers look good. Thanks, I might have to try those. I'm also looking at the 130 grain Nosler etip.

I have some .308 150 grain etips I just got that I'm going to load for my 30/06.

Let us know your results if you can please. I just tried some of the Barnes TSX 130 grain with less than stellar results so far.

Hi Bob.  My son used 130ttsx in is 270, loaded at 2630fps to keep he kick down, and took a bear with it with no problems.  I'd have no qualms using the 110ttsx.  Though if you are doing it to reduce kick, it might not be a noticeable difference.  We're currently working on a 150 lrab or 145 eldx load, might have to try the bergers as well.
