OhmyGod!....what was I typing? 30 degrees
IS correct, and I should be flogged!

Can't explain the error, must be the meds, just a mistake to be sure.

Thanks for bringing it to my attention.
If someone WAS to wildcat the 204R case, because of the increased case capacity, somewhere around 1.5% I'd guess, there WOULD be a very slight boost in velocity, but we all know the rule that states it would be very, very small, and at least to me, not worth the overall effort when you consider the reamer cost, fitting and chambering fees also. Eventually though, somebody somewhere will built one though, they always do. Ya got me though,
Silverfox.....that's what I get for using a CRS brain to bring up something that should have been looked up properly (or at least remembered correctly!)
Schrutester: The reasons behind that statement were arrived at after reading the piece by Bill Craig in SCN when he built his 9 twist 204 for the 50 grainers. The basis for the change from the 223AI is due to the extremely high BC of the 50 grain .204 bullets compared to the .224" offerings in the same weight range. The article lists many loads, and the velocities range from 3,150 fps with 4064, to 3,646 fps using RL-15, which printed a .047" group in the authors rifle, a M700 switch barrel rig with both a Shilen 223AI barrel, and the 9 twist 204R barrel.
The 50 grain .204" bullets will shoot at long range much more effectively than any 223AI shooting .224" 50 grain bullets. I've hammered prairie dog towns with my 223AI and 50's for ten years, but for the same task now, I'd prefer either my 11 twist 204, or even my 12 twist 204, as they both just shoot flatter than the 223AI. They are both excellent calibers, but my preference runs to the .204 side of things these days. (But 223 brass will always be much cheaper and easier to find if that matters........)
If Todd Kindler has his way with the bullet makers, we'll soon see more .204 bullets in 50gr, and even 55 and 60 grain VLD's for very fast twist rifles for use at 1,000 yards. Stay tuned, I'll be speaking with him next week to see if he's made any progress in that regard.
