Good looking gun. assume 9 twist barrel there?

Try the JLK 168 BC .690) and 180 BC .738) when you can.

head down to Iowa when you can to shoot 1k BR and plan on shooting the Nationals on Labor Day at the range in Ohio. they will also have a mile match.

Re: 7mmWSM project completed

hey nate...

i have been shooting berger180's and 140 nosler bt's for my best accuracy.. this is on a hs precission vertical grip adjustable lop/cheekrest.
how many shots do you expect to get out of your barrel.. i am up to around 550 or so shots(have to look at my book) and i am getting quite a bit of copper.. whatam i up against.. this barrel is shooting better now than it ever has but i am getting copper now. am i on the barrels downside or what???

Re: 7mmWSM project completed

Nate,

Ours almost look like twins! It turned out very nice, great job! [img]images/icons/cool.gif[/img] Looks like it fits in there like it grew there. [img]images/icons/smile.gif[/img]

Did you machine the block? Is the bore in your block 1.2, or 1.25, a little smaller than the 1.35 in mine?

Re: 7mmWSM project completed

Brien,
thanks for the compliment.
first of all I'm a fairly new gunsmith and this is my first experience with the 7mmwsm
but I will be dissapointed if acuraccy drops off before 2000 rounds.As far as copper showing up now I would not say that is a sign of your barrel being on it's way down.(thinking out loud)In my experience if a barrel is cared for properly they only get smoother. is it possible for a barrel to get to smooth and have more surface area touching the bullet perhaps pulling more copper off.In my mind machining marks running true with the rifling is not a bad thing but other obstructions like copper deposits or machining marks that don't run parralel with rifling will cause excessive copper fouling take it for what it's worth and correct me if I'm wrong, hope to never stop learning.

Brent,
thanks for the compliment.
Yes, I did all the machining on the block.The bore is 1.25 for 10" then straight taper to .950 at 30"
