270 WSM help

[mauiarcher]

I am looking to build a Tikka in .277 with a 20" barrel. I thought I was gonna hit the easy button in a 6.8 western chambering. However, it appears that I may be able to get another 150 FPS +/- in .270 WSM throated long to shoot the heavies (berger 170 or 165 ALBR) and of course with a fast twist barrel. I read .220 freebore might be good but apparently I just can't specify the freebore and the barrel maker (Carbon 6) requires 3 dummy rounds.

I don't really want to buy dies and brass yet with a 6 month lead time on the barrel. Anyone who may be shooting either 165 ALBR or 170 grain elite hunter willing to make 3 dummy rounds? Happy to pay for components and shipping. Thank you in advance.

Also looking for any feedback from those who may have traveled this path already. Is it even worth it? Am I on a fools errand chasing diminishing returns? Am I wrong and the real difference is only 50fps? Don't plan to shoot factory ammo but I guess it's a plus.

Are you still looking for this? Send me a PM and I can give you some information on the 165 in a SAAMI 270 WSM chamber.

Thank you for the reply!!! Would have loved to see this project through but without a local smith I went a different direction. With the .007 difference, I don’t think the juice was worth the squeeze and ended up ordering a 7 saum. It seemed to make more sense to me as I have the saum dies, brass as well as bullets on hand from my 7 prc. I use was able to send the dummy rounds to carbon 6.
