I've become a fan of ER Shaw barrels after having seen several rifles built with them by my gunsmith buddy. these were all CoMo barrels. They all shot around 1/2 MOA with out really trying hard. They were bedded, and generally accurized but it looks to me like paying 3 times as much for the barrel "might" have bought another 1/4" reduction in group size which may or may not be worth it depending on your hunting mission.
I have one on the shelf, #2 taper in .338 1:10 twist, to chamber in .338 Federal when I get a break from ground hog hunting and two more on order, one to make a .25-06 barrel for my Wife's sporterized 03 springfield, one in 6mm 1:14 twist to make a 6 Dasher barrel for my Savage Model 10 for GH hunting. I'd rather have Shilen's but can't justify the price difference. For me, since I chamber my own barrels, they work just fine, and I get the equivelant of 3 new rifles to play with for a fraction of the cost of new rifles.
