.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?

The TTSX should be stable in your rifle. It's strange that it's not

Shoot the TSX again and get a 5 or 10 shot group and see if you have any key holing. You might just have to stick with it over the TTSX

Ill try it out again and see what happens thanks for the advice
