I going to take one of my 30-06's to the gunsmith and have him put a 338-06 barrel on it.
From what I can determine from the data I've looked at. It will send a heavier bullet, down range, at the same trajectory as the 30-06 with quite a bit more ft/lbs of energy and bullets with a higher SD.
The only draw back I see is the availability of unprimed brass. I've found some Weatherby and some A-Square but at a very expensive cost.
They do sell an expander ball that can be placed in the 338-06 sizing die that will size a 30-06 case to the proper dimensions in one motion but, the brass still says 30-06 after sizing.
Is there any one that shoots and loads for the 338-06 that has been able to find reasonably priced brass with the 338-06 A-Square head stamp?
I have also noticed that the data I've been looking at. Shows the 338-06 trailing by only 200 fps in velocity behind the 338 win mag, with the same bullet. That a lot of thump. How true has any other shooters, of this fine round, found this to be?
This should be one very good elk round, or any other game in North America, out to 250 plus yds. Very impressive. I think the only thing that will keep it from getting popular is the fact that the 338 win mag is already popular with so many hunters and factory fodder is readily available in any store that sells ammo.
It will throw a 210gr faster and farther than a 30-06 will throw a 180gr and a 250gr at about 2500 fps. with more than 2500 ft/lb of energy at 200 yds. This is all out of the same case as a 30-06. Absolutely amazing.
