Re: WTS: Winchester 338-06 AI
Cheezie, Those sound like some healthy loads... The reason I went with the improved shoulder is because I wanted that slight increase in case capacity(obviously). A velocity gain didn't interest me in the least. What was important to me is chamber pressure, especially in the hot African climate. With the extra capacity, I should be able to use standard 338-06 max load data for the improved case and still have sane pressures, in theory at least. Some would say, "Why not use the 338 win mag?" Simple, I do not care for a belted case.
In my 35 Whelen Improved, I could easily reach 2600 FPS with 250gr pills(using Varget), and the brass would almost fall out of the gun. I guess this helped sway me towards the improved chamber as well. For the record, IMR-8208 XBR is a kick anus powder for the 35 Whelen. I'm still doing testing, but the accuracy is INCREDIBLE! Probably more than you wanted to know, but there ya go anyways.
