Well I was really soul searching the last week or two about what to do, I posted up a couple questions asking for opinions and got some great feedback.
Keep my 300 RUM or rebarrel to 338 edge
In the end it came down to althought I am very happy with the performance of the 300 RUM, I wasn't too keen on the barrel life and I wanted better accuracy than I was getting from the factory barrel.
The donor is a BDL SS 300 RUM bedded to a Hi-Tech specialties 26oz stock.
Figured if I was rebarreling then why go half way, so I phoned up Rocky Mountain Rifles in Dawson Creek and talked to the gunsmith for a half hour or so.
He just happened to have a .338 1:9.5 twist 30" Benchmark SS 5R Fluted 4.5/sendero contour blank in stock with nobodys name on it. Blank weighs 3lbs 13oz and nobody's name was on it....there is now.
Barrel length will probably be 27-28" + muzzle brake
Full Action blueprinting/truing
Wyatt mag box installed
Holland QD muzzle brake Installed
Match Recoil Lug
Bedded into my Hi-Tech stock
Chambered in 338 Edge and throated for 300 SMK
I'm a touch worried that with the lighter stock its gonna be terribly muzzle heavy but I'll cross that bridge later.
My preliminary math suggests a naked rifle weight of 7lbs 11oz
I'm stoked, now I just gotta send em the donor.
ETA is March
