seating depth of barnes tsx
You guys shooting the tsx is the - .050 to -.070 seating depth barnes recomends where you are finding the best accuarcy?

The problem is in my 270 wsm at -.050 I'm already compressing 64 grs of Re22 and I'm not even to max yet.

Even though barnes might still recomend it I think the .050" rule started with the older bullets to help alleviate pressure problems. It would be my recomendation that you might start with the same "jump" to the lands that other bullets you shoot in that gun are accurate with. Regardless if you move the bullet up to say .020" it isn't going to change the "compressed" powder story very much. Powder can be compressed quite a bit with absolutely no negative effects. You should hear/feel what it's like when I put 84 grains retumbo in my 300 mag......that's compressed powder!!

The .05" thing is a guide. It may or may not work in your gun. You may need more or less.

The .050 starting point has worked pretty well for me. I'll continue to start there, with standard bullets, usually start at .030.

I load for 2 rifles with the tsx. An A-bolt, which the magazine length wouldn't allow me to get anywhere near the lands, so I started as long as I could. The other rifle is a Sako. I started at .050 off the lands.

The accuracy was so good in both rifles I didn't see the need to seat any differently.

In my experience loading the TSX, the powder and more importantly the powder charge were bigger factors. If it ain't grouping with powder X go to powder Y before spending a lot of time (or any) on the seating depth. And I have found the Barnes recommended powders to have worked well.
