Reloading for TRG-22 in .308

[jankovig]

I'm a complete newbie when it comes to reloading, but I would like to start reloading for my TRG.

I've read through the ABCs as per everybody's suggestion. I also read through tons of topics both here and on sniper's hide.

As far as the press goes, my mind is set on the Forster Co-ax. Currently my biggest stumbling block is what type of dies to get: bushing (full or neck) or regular dies. I like the idea of bushing dies, but the neck diameter difference between the fired and loaded round (federal gold medal match) is about 0.007-0.008". Loaded round measures on avg. 0.338" and the fired round 0.345". All the once-fired brass will still chamber without any issues.

Redding recommends to get a bushing that's 0.001" - 0.002" smaller then the diameter of the loaded round. If I do this, now I'm trying to re-size the fired diameter 0.009"-0.010"!!! Is this too much to do in one resizing? Is it even possible to do without damaging the brass/die? Should I get a second bushing size that's about 0.004" bigger then the final size, to use as an interim step?

What are your thoughts/recommendations?

I'm using a .331 bushing on my Redding Competition neck sizing die for my TRG in .308

Lapua brass, and 155 gr. Hornady A-Max bullets.

No issues with one resizing, and I've reloaded a lot of rounds for this rifle.

Go with Reddings recommended bushing, it will resize them without a problem. I would also buy bushings .001" under and .001" oversize, not all brass is the same thickness.

Kirk,
did you turn your necks? If so, do you get a "donut" developing at the neck-shoulder junction? I guess using lapua brass, the necks are pretty uniform, so there's no need to turn them.
