Suggestions for loading Barnes TSX in 270/06/30-30?

[bison]

I live in CA and need to switch to non-lead fairly soon for my 270, 30-06, and 30-30. I picked up a few boxes of Barnes TSX's that match what I shoot now in those calibers (130, 165, and 150 grains respectively) and need to work up loads - suggestions are highly appreciated!

My current loads are:
- 270: 53gr H414
- 30-06: 57gr IMR 4350
- 30-30: 32gr H4895

I have the powders above plus Varget and H335

I see Barnes suggests what looks like somewhat lighter loads for the '06 (53-57.5c of IMR 4350). They don't list anything for the 270 using H414. For the 30-30 they list H4895 as 29.2-32.4c, so also looks a little lighter than I've used.

Thoughts/advice?

thx

I’ve always been told and it makes sense to me. With Barnes TTSX bullets always load one bullet weight under what most would consider normal grain weight cup and core type bullets as the Barnes TTSX have no problem on the penetration and weight retention front but need velocity to do their magic.

From my limited experience with Barnes bullets in 25-06, you will need to back off your typical loads at least a grain or two. Barnes bullets have a lot of bore resistance so you will get pressure signs earlier and lower velocity than you got with lead core bullets. I was unimpressed with there on game performance so if I had to use a copper bullet I think I would try a Hornady gmx. Barnes does have load data on their website specific to their bullets.

I’m using their ttsx in a 130 grain in my 308 you need velocity to make em open up

I loaded 270 Win. with the Barnes 110 TTSX. Two loads using 58.0 of IMR4451 and 58.0 of H-4350 gave me 1 MOA accuracy and good speed 3200+ FPS.

For my Mod. 70 30/06, I used 57.0 of IMR 4350 W/ 150 Barnes TTSX. Also about 1 MOA accuracy. I stopped there.

Work up loads in your rifles. There was no data using the IMR 4451 load with the 110 TTSX. I worked up to 58.0 grains and got 3240 FPS and great accuracy with no pressure. I stopped there. The 110 TTSX is for Antelope, Deer and Hogs. If I was going for Elk, I would use the 130 TTSX.

If you already have IMR4350, you could use it for 30/06 and the .270.

Well I loaded up a few yesterday and ran into one problem...

For the 30-06 I loaded five rounds of H4350 at 54, 55, and 56 grains each (53-57.5 is recommended range). Will try them today.

For the 270 I also loaded 5 with H4350 at 50, 51, and 52 grains (49.1-54.5 range). I ran into a problem getting the COL right... 3.30" is the recommendation, but as I tried to dial that in the bullets seem to "jump" from about 3.31" to 3.275" or so, perhaps due to the position of the cannelure? I couldn't get anything in the middle of that range. Better to go longer or shorter than 3.30"?

For the 30-30 I loaded some with 31 grains of 4895 (29.2-32.4 range).

thx

Think I’m running the 168gr TTSX at 57gr IMR 4350 (30-06)

I’d probably try longer myself on the 270

Barnes recommends you jump the bullets .050". TTSX are better than the TSX. When you buy more, buy the TTSX, they have a more open hollow point than the TSX. There are no "Cannelures" on the bullets. They are driving bands. Go lighter than lead bullets. That's why I went with 150 grain in the 30/06 and 110 Grain in the 270. Speed helps the all copper bullets. If I ever load for my 308 win, I will buy the 130 TTSX.

I run my 270 110 TTSX @ 3.255". My measured length to the lands in my Tikka T3 is @ 3.394". I got a 2.27" 3 shot group @ 300 yards with that load, about 3/4 MOA when I tested it at distance. I'm good with that. A friend of mine shot the same bullet in his 270 last month with the 58.0 Grs. of H-4350 load and took a great Antelope in Nevada with it.

The 150 TTSX in the 30/06 I run them @ 3.285". My measured distance to the lands is 3.335" in my Mod 70 Classic.

If you can't measure your actual distance to the lands of your rifles, go with the recommended COL from Barnes.

I'm getting great accuracy for my rifles @ those COL's. YMMV.

Let us know how it goes.
