[QUOTE="el matador, post: 1149701, member: 12193"] I have a Pac-Nor barrel in 270 WSM. It's a 24" 3-groove #5 that shoots anywhere from low .2s to mid-.6s depending on how picky I am with my hand loads and how patient I am with barrel cooling. I really like it. As far as I know they just have one reamer design, and on mine it puts the ABLR out at 2.9" touching the lands. They may have a throating reamer that could get you out a bit further. The 270 WSM is about maxed out in a short action with 150 grain bullets. You can shoot bigger bullets of course but you start eating up case capacity and you get marginal gains from going heavier than 150. The only way to get around it is to seat the bullets out a ways further but then you're looking at a longer action and you defeat the purpose of the WSM. I decided to stay with the 270 WSM when I rebarreled since I already had a bunch of brass, dies, bullets, etc. It would have been nice to squeeze some more performance out of it, but I just use it as a medium-long range round and it works very nicely. It's fine for target shooting past 1000 and I'm comfortable taking deer out to 800 if needed. Took a nice muley this year at 563 no sweat. With your somewhat generous weight requirements I would probably go with a 26" barrel and the 165s should do pretty well. Talk to the guys at Pac-Nor about your contour, twist and throat requirements, they were very helpful in my case. [/QUOTE]
