Re: Blank check build - most accurate 1000yd rifle.
*Straight;
I apologize for my sarcasm regarding integrity. It was in bad taste, and not intended as any criticism or mockery of you or of your craft.
My thinking was more in the direction of catering to largess; of indulging whims that profess to create implements for accomplishing the impossible.
But in point of fact, there's really no good argument against that. It is a valid pursuit, and is the means by which one endeavors to stretch the envelope. If someone wants to invest their hard earned valuta in such pursuits, more power to them, and to those who empower that pursuit.
Having said that, here's my vision.
Starting with the barrel, the blank check figures prominently here.
I have often made comment regarding the Lothar-Walther
Ultra-Lightweight Barrel. This is, in effect, a sleeved, tensioned barrel, that also provides a highly effective heat dissipation capacity. I'd have one myself, but until recently, my funding could not support such an indulgence. Now it can, and the only remaining impediment is the lack of a suitable project. This one could suffice.
My barrel would be a L-W Ultra-Lightweight, 28" long, 7mm bore, 1:8" twist. I would provide it with a SAAMI .280 Remington chamber. The chambering is easy to load for, and easy to find accuracy with. The barrel and twist allow it to project highly efficient bullets to well, well, beyond 1000yd.
The SAAMI spec allows any factory load, and eliminates the need for neck work.
The chambering holds enough potential that any accuracy loss due to the SAAMI neck would not be a serious detriment.
Further, it achieves its efficiency without straining any pressure limits. Meanwhile, the entire package stays well within human limits regarding energy expenditure and the ability to endure sustained fire. I like the idea of employing adequate, rather than overwhelming, energy.
A 175gr 7mm VLD bullet, going supersonic at any distance, is going to ruin any critter's day.
Stock; any one of the McMillan A-Series Tactical stocks, with filler that best supports the action.
I'm no good with selecting actions, my prejudice toward Savage disqualifies me from giving such advice, but whatever it is, I'd have McMillan pillar bed the rifle into their stock. They did mine, and it's one of those beloved rifles Chad remarked upon; much used, twice rebarreled, and still as far from its retirement as I am from the grave. I know I'm talking to a gun building artist, but this is one step I can suggest from experience, and with confidence.
Barrel, action, stock; at this point, the buyers' personal preferences outweigh anything I'd choose to suggest further. But at this point, the rifle I'd want has its core values indelibly established.
