First time TSX,TTSX user here.
Looking for a good load for my Roberts. Pretty much just looking to load some up, sight in and kill some does. I see Barnes has online load data for the 100 TSX, I assume I can use that data for the TTSX? Also does it matter where the case mouth ends up? On or off a groove?

Wes

I have very little experience with the TTSX, but I did just load up a batch for my 25-06 (I used 80gr - I have 100 gr as well but haven't gotten around to them yet). I used barnes data off their site, and didn't pay attention to the groove (best seating depth was on a groove at .050 off the lands). For me, deeper shot better.

wes,

Try 46 grains of H4350 with the 100 TSX/TTSX. Can push it up to 47.0 - that's the load I use in my Kimbers.

46.0 grs IMR 4350 and a 100 gr. bullet of your flavor has worked well for me.

Same load i use in my Ruger UL, watched another nephew use it on a 7pt. WT buck last deer season, has a serious bark when it goes off, and a dang hard bite when it gets there, the little buck shuddered hard and fell at the shot, with both shoulders punched at 80 yds.

Thanks guys. I have some IMR 4350 so I'm set.

Gunner, I'm also using these in a Ruger UL, tang safety.

10-4, good luck Wes, your gonna love that little rifle

I've emailed Barnes a few times about that and every time they tell me that I can use the TSX load data online for the TTSX. I've not has issues using the TSX load information for the 338 Federal or 350 Rem Mag.
