Ok. How much are you jumping those? Are you running that COAL due to mag length, or that an optimal length for the case bullet combo? I'm leaning towards a long action and long throat to be able seat bullets out for optimal case capacity.

Rich said the standard reamer is 2.965 to the lands with the 250 berger. I'm using an accurate mag and there's a bit more room left but am still playing around with the coal. I've had the 250 up to 2859 fps, once I get better brass I'm sure 2800 plus with good brass life will be very achievable. Doc is faster with his longer throat, 2900 or so.

That's some big medicine Doc. I like it!
Doc- Thats some impressive performance your getting! I may be going a similar route with a Tikka build in 338 SS. Are you using the stock stock? Do you know what yours weighs as built?

I built the rifle using the original stock and had Dennis epoxy bed the action. I supplied him with a titanium recoil lug and pillars from Lumley. I bought an after market magazine and bolt stop from Mountain Tactical (in Montana) and this allows you to seat your bullet with disregard to limitations in length. I'm seating my final load using 250 Elite Hunters at 3.040" which is exactly .020" off the lands.(and there is room to seat further if I had the need to)
I have never felt more accomplished than to have this gem in my gunroom!...it's not often you can find true magnum performance in a short action platform!! I will post a picture of the magazine and let you know the weight later when I get home tonight.

As built, my rifle weighs 9.7lbs w/o the magazine. I used a Leupold 20MOA rail and UTG rings and a Zeiss 3.5-15 HD5(sent to Kenton Industries and had MOA turrets installed)
Attached is a pic of the magazine from Mountain Tactical and there's plenty of room for longer pills

Is there a need to turn necks of using ADG brass from Rich ?or just neck it up from the 7mm neck to 338 and go.
