Re: Building a long range big game rifle, suggestions?
Marine Sniper,
What rifle are you using for the 408 CT?
The main problem I have witnessed with this round is the bullet selection. There may be some lead core 408 bullets on the market here in the near future that will me much better as far as accuracy over a wider range or bore dimensions.
The 30-378 is a good round but For elk at 1000 yards I prefer a 338 simply because of bullet weight and diameter. To be honest either caliber and also including the big 270s and 7mm rounds will do well at this range but the 338 will be more effective with those hits on the fringes of the vital zone.
I have designed a big 338 wildcat based on a 408 CT case which should be able to hit 3500 fps with the 300 gr ULD RBBT bullets in a 34" barrel. This is roughly 100 fps faster then the other 408 based 338 wildcats. Is this meaingful at extended range, not really, But the round is really designed around the huge 350 gr ULD RBBT drive to near 3300 fps, or at least this is what we are predicting.
Yes as mentions I also will have a 510 Allen Mag out soon as well but the big 338 is already here as I have the reamer for it. Just waiting for my BAT receiver.
With a rifle weight of 25 lbs you can use pretty much anything you want and it will be comfortable to shoot.
As you know stick to the heavy VLD or ULD bullets and you will be served very well with most of the larger rounds available.
If you have built your rifles before I would agree that this would not be a difficult project for you as long as you are using proper building techniques it is all the same thing.
Personally though, a big 338 is hard to beat. I prefer the 338 Kahn(338-378 Wby W/35 degree conventional shoulder) over the standard 338-378 but there are no flies on either. The big 338s are generally easier to find a quality load for and if you want to shoot alot they will last longer as far as bore life goes.
Good luck, let us know what you decide to build.
