When it comes to reloading them, (in the 7-08) I've got both. Can't really say which is better. I've gotten lucky enough to have picked a good set of RCBS dies for the 7-08 and get little to no runout with either the R-P or Win brass.
FWIW I've finished 4x loading's with the Win's and have seen no trouble, only 2x with the R-P, both showing good resiliance in the neck.
And your right, the Fed brass and ammo is junk, the necks just seam a bit thin and hardnened after only 2x,they found the scrap bucket real quick.
We had the best luck with Winchester Supreme factory ammo in 140 in our Handi 1-10, it at least gave 2" groups at 100. We tried Winchester and Remington ammo in 140's and 150's. It was buying factory ammo for that gun that finally (and thankfully) pushed me over the edge to start loading, that was alot of $$ for so-so accuracy.
