Re: necking the cheytac
It's called a 300 Hulk I think, I could be mistaken (probably am). Tom Sarver is one of the primary developers and shooters of this round. He's a member here under that name.
The limiting factor on something that big is the barrel life of a 30 caliber overbore. The 300 Kong was discussed last week, it's a 30-378 Wby case with a standard shoulder profile blown out and body taper removed. 137gr of water capacity.
The 30-378 shoots a 240 SMK around 3300 from some of the data I read, so taking a SWAG on the capability of this would be somewhere in the 3400-3450 range.

Correct. The 338/408 is a bit on the extreme side as well but works simply great. No reason to go to the 30 cal bullets cause they wont stay together and you get just as good as balistics out of the 338 bullets vs the speed difference.

Thanks for clarifying that. I've been reading a bunch about the massive overbore 30's and 338's lately and I've managed to get them all befuddled in my mind.
I'm starting to think that a barrel burning 30 with a bullet in the 210-220 range with a BC around 1.15 or so (might be possible with a precision turned solid) would be a total monster to beat.
The case capacity of the 300 Kong opens a lot of doors for throwing 210-240 grainers VERY VERY far

Your barrel life will be around 200-300 rounds. The 338 is bad enough. I have a 30/338 and its a great round for a packable hunting rifle and its very accurate out to 1800 yards using the 210 bergers and the 240 match kings. I can push the 240's right about 3050-3100 depending on the weather. I have some 220 grain lost river bullets that im planning on playing with in this. We be some time before i can get some good results and if the bullets are not available i am going to get someone to produce them for me if they work good.

I'd really like to see what you come up with for that. I was expecting about 500-700 rounds since the dimensions seem to scale appx. what a 22-284 does. 2-300 sounds a little low, but for something like this owning the reamer and setting it back myself is probably a complete necessity anyway.
I'm sure you'll have something to be lusted after, I can't wait to see it.

Re: necking the cheytac
The 200-300 rounds is what i would expect out of a 30/408. The 30/338 lapua should get 1k without any problems and maybe even get up to 2k if not abused. Its a hot round though.

Gotcha, yeah, I wasn't thinking of a 30/408 but a 300 Kong. I don't know what the water capacity of the 408 case is. The referenced capacity of the 300 was 137gr of water. The 408 is probably another 20-25gr I would guess.
In that regard yeah, I agree completely, 338 is the smallest I'd think about going.

wow! Depending on your results, I think my plans just changed.
