.280 rem loads for Ruger Mk II 1-9.5 twist

[Quietking]

I’ve been trying out different load recipes for my .280 rem. I believe I have one down for the Barnes TSX 140grn. I tried the same recipe for the TTSX 140 grn. and it seemed like they were tumbling at about 150-165 yd shots. Any recommendations for a recipe with TTSX ? I was doing 51.5 grn IMR4350 with TTSX 140grn and Win primers. I was able to hit bullseye every time with the TSX with that same recipe , but the TTSX where not even on paper and the one that did tore a rectangle through it.
Im also barely learning how to reload so bear with me haha.

are you set on the 140 TTSX? Or copper for that matter?

Sadly yes I have to use copper for hunting. 140 not so much but I just bought those i can always sell them / trade them out for difrent grain

are you set on the 140 TTSX? Or copper for that matter?
