243 Win load for Barnes TTSX/TSX

[D.B. Cooper]

I want to develop a load for caribou hunting for 243 Winchester using either the Barnes 80 grn TTSX or 85 grain TSX, but I want to use 4895 powder, and I haven't found 4895 data for those bullets. Does anyone know or have any experience along these lines? (Or does anyone know of a printed manual containing such?)

I want to use 4895 because I had good results with it in this rife with Sierra 60 and 90 grn bullets (yearrrrs ago). It works well in my M1, and I have a bunch of it. (Of course, if it doesn't work, it doesn't work.)

Also. I'll be testing loads in the winter, but I'll be sing them in the fall. In what ways will temperature and humidity affect accuracy and velocity?

You didn't specify which 4895, but either way, hodgdon online has data for both with an 85 tsx. I'm using imr4831, but I really did LIKE 4451 for 85-90 gr monometals with max loads and temperature insensitivity, I just went to 4831 for more speed, but it's my winter varmint load, if I was truly worried about temperature, I'd run the 4451.

I saw that earlier, but I thought that data was for Hornady branded bullets. Taking a second look, I do see one Barnes bullet category.

Reloder 17 is the best that I have found for the 80 grain TTSX.....

Also works well with the 80 grain TTSX in the .25/06 ...

Thanks.

I'm really hoping to work with 4895, just because of logistics, but really...I won't be loading thousands of rounds of this stuff, so if RL17 is the hot ticket, it won't be the death of me to buy a can.

Email Barnes, they have IMR 4895 data. Although looks like hodgdon has the data.

I’m shooting 39.5gr IMR 4895 with the 85gr TSX.

I have used IMR 4895 in I think every rifle I have, I think I used data from Sierra with Sierra bullets in that weight range. I have been toying with the TSX in my .243 using VihtaVouri powder N560, Norma MRP and IMR 4895 (I think). I'll have to check later in my shop and see.

My favorite load in my .243 is alot of N560, Fed 210 match primer and a Hornady 87 gr Vmax. I don't know how big Caribou are but that load is very deadly on lung shots to Antelope out to 350 yards.

Big enough I needed a winch to get into the back of my Ranger side by side...and that was a small one. I'm figuring 250lbs and up.

So are you just using load data for 4895 and any old 80 or 85 grn bullet? (Not Barnes TSX specific data?)

I have been known to do that but I usually read one or more manuals listing that powder for the same weight bullets and then start loading lower weight charges and working up. The TSX is a longer bullet than a comparable weight copper/lead bullet so it could have more bearing surface, even with those ring grooves I think I measured the bearing surfaces to be more than what a Nosler or Sierra bullet has so pressure could be higher with the Barnes than others.
