1-pointer, I have to agree. Most calibers lose less than 30fps, per inch shortened barrel length. But you never know till ya know, sometimes.
I have loaded the old gun with R-25 in the 150s with good speed, but it just never got good accuracy at the higher pressure loads. Haven't any R-26 on hand and hate to buy just to try. Though I would or could make use of some 26. So I will take that into consideration for a try ,before leaping into the rechambering.
The .270 Weatherby operates at lower pressure than the Winchester cartridge. That's one reason I looked at it initially.
But it may only gain 100fps overall with the 140 + bullets.
That wouldn't be worth it.
