Anyone loading the Barnes TTSX in 6.5 Grendel?

They recomend RL15 for the 100 and 120gr. I've read mixed reviews about RL15 in the Grendel. What say yee?

I use 8208xbr and that works well, not sure about RL15. Also, I would focus on the 100 v. the 120 to keep the velocity up to maximize expansion.

^thanks. I was thinking along the same lines about the 100gr. I've never tried to take game much beyond 200yds so the lower bc of the 100gr pill may not be a factor.

I had planned on using Nosler CC 123 with 8208 XBR.

Try Benchmark or H4895. Currently, I'm using Benchmark with the 100 ttsx. The load has shot really well in 3 AR rifles, holding moa or less out to 400 yards. The load has taken several bucks with very good terminal performance from 60-120 yards.

200 yards or under it won't make any difference. If you push into the 300-400 range, the 100TTSX will probably still be going fast enough to expand properly, while the 120TTSX will likely have slowed too much. But it will ultimately depend on what your load is and what you are hunting (and of course your marksmanship).

Thanks for the feedback. Once I find, load, and shoot the 100gr ttsx I'll report back.

Update, found some TAC TX 100's at Vizards.

Update (kinda) :
I loaded up some 100gr and 120gr TTSX with Federal 205's and RL-15 as per the Barnes data. Stepped the powder load by .3 grain increments up to their max. All 2.260 COAL.

I think I'll primarily fire these out of my Satern 20". Just waiting for things to dry up a bit before I test.

I also have some 123 SST I want to load with RL-15 as per the Nosler data. They have loads specified for their 123gr HPBT.

Finally shot a few different loadings for the 100 TTSX (dunno why I wrote 110). The hottest one (29.6 reloader15) seemed to do the best. 205 Federal primers. Don't have a chrono yet. Also shot factory SST and ELD for comparison. 20" Satern barrel, 100 yards on bags.

My experience (largely gathered from Divernhunter) suggests that the Barnes bullets tend to do better towards the max end of their loads.

My (Divernhunter's really) experience suggests that when you switch from pure copper to gilding metal (or vice versa) you should scrub your bore.

I updated the www.msrhunt.com 6.5 Grendel community reloading data spreadsheet with your load.

Nice shooting. I've also found the ttsx likes to be pushed fast.

I loaded the 100gr TTSX with 8208XBR in increments. I don't have the info with me right now but I want to say I went up to 30.6gr. Its a compressed load and I started to see pressure signs, so be careful. I got 2806 fps from an 18" Satern barrel. I was very happy with the velocity, but my precision degraded as I increased charge. It went from something like 0.75" to 1.25" from bottom to top of charge scale.

I am going to do a new ladder and retest. I had a lot of muzzle braked rifles near my that day and was flinching some. I also will scrub the bore big time before. I didn't clean it and went from amax rounds directly to the TTSX. I knew that was a bad idea, but was in a hurry.
