Here is where I am at.....I have a hunting blind/cabin/benchrest/shooting shack which is on a big ridge and is also on 25 foot stilts I use during deer hunting. We are able to see and shoot as far as we want to...not that we do. I have a spot that I want to bait that is unhuntable up close. It is 1375 yards out. I usualy have my 1000 yard LG set up in the cabin. BAT 8.5 M with a magnum bolt face. I have been considering screwing on a 338 EDGE tube, which is all the firepower I can come up with without buying a new bolt.
The only thing holding me back is the fact that I have a 30 cal tube now spitting out 210 VLD Bergers at 3275 FPS. The chrono was telling me 3230 and I didn't believe it so I did a drop test out to 1000 yards on my range.....I actualy had to INCREASE the velocity to 3275 in the computer to make the drops work out!! I tested and retested. I didn't show ANY psi signs (other than the chrono data) untill I was 2 gr hotter and I got the telltale "click" or "hitch" at the top of the bolt lift. I also got slight primer cratering also.
From what I have read here, the most I can expect from an Edge would be 2800 fps with the 300 gr bullets. On the other hand, all I can "expect" out of a 300 WBY is 3000 FPS with 210 gr bullets!!! Plugging those numbers in the computer shows an increase in energy by 400 lbs with the 338, from 1100 to 1500, but a loss in FPS over the 210 vld. Now, I know the phrase " no replacement for displacement" could apply here....At those velocitys will the bullet open up? A 338 hole is bigger than a 308 hole.
Do any of you/would any of you go through the expence of a new tube for this platform? BBL, gunsmith, brass, bullets, dies, cleaning supplies, ect...
