Also, if the Barnes websight doesn't have the powder you use to reload. Get their loading manual. Because of the banding reduce internal barrel friction, the TSX/TTSX take a few more grains of powder than typical.

I checked my notes and I only had load data for Varget.
130gr 308 TTSX Varget min 47.5 to max 52.0
150gr 308 TTSX Varget min 43.5 to max 48.0
I found Federal brass did not have the capacity to reach max powder charge. I liked the 130gr best. Optimum charge weight was 48.9 grains of Varget with a COL of 2.780.

Wow, I just can't stop this morning. I found brass to be the biggest discriminator for my group size. Each manufactures brass has different hardness, thickness, and internal volume - all affecting bullet performance. They will all group differently in group size and POI. Don't mix brass, keep each manufacture separated. You will likely find that your rifle will take a liking to a particular manufacture. I even went as far to group like-manufacture by case weight (same weight = same internal volume). Heavier cases have less internal volume and higher pressure for the same charge.

Not that I have tried THAT MANY rifles (5), but every one I have reloaded for did significantly better with Nosler Custom brass than any other make. The .204 Ruger M77 also performed well with Rem and Win bulk brass, but even here the Nosler had a definite edge in performance.

Yup, I've found that the weight difference as high as 25grs between different manufacturers. I don't use Winchester any more for that simple reason, in fact try loading 2 .308 cases one from federal and one from winchester with 44grs imr 4064, then look at the charges and compare and you'll see what I mean.

Can't say that one is better than the other !!!
My limited testing with the 7mm08 has shown the different brands I've tried all gave good results after some tweaking.
The best way I've found to do this is with a chronograph.

Im just a sloppy reloader cause I dont even sort my brass anymore. if the case is still good, no signs of wear n tear it gets loaded. its all a matter of how good a group size you are aiming for ( pun intended) if you are happy enough with a minute of deer, well you dont need that last little bit of tinkering. if you want super tight groups well thats a whole different ball game when consistantsy is the name of the game.
different strokes?

How long ago did that happen?!?! How long had it been since he cleaned his barrel before he shot the Barnes?!? |
I think you hit on the problem right there. It always amazes me how often people don't know how to thoroughly clean a firearm bore. I've bought an awful lot of "poor shooters" over the years that just needed a good cleaning. Start out with a fouled bore and the homogenous bullets will foul faster...the groundwork has already been laid!
