I have a 1 : 10 twist .375 Chey Tac rifle being built at the moment, so it would need to work in that for me to buy it.

I'm a 10 twist fella. Thus my thought for greater than 350 to around 400 something.

A jacketed bullet yes a solid turned bullet no. Ive been keeping an eye on .375 bullets for about a year waiting for a bullet I feel suitable and affordable for my next Wildcat project. I don't feel that a .535 bolt face or anything less than a .590 will cut the mustard which will kill its popularity right off the bat and is probably getting the cart in front of the horse.!

The 10 twist probably wont cut the mustard for a 400+ high bc bullet guys a 8 twist or less is what you wont for a bullet like that.

Would be of interest. Dave Viers had some success with GS 414gr with progressiv twist machined solids. The best BC with smk is .78 in 12 twist and something for 10 twist would be good.

The Cutting Edge 400 gr. Is awfully close to what you are talking about. It is really accurate out of a 13-6.5 gain twist I have been shooting.

Just for fun I did some numbers on a 400gn Lead core bullet design.

Given.............
Bullet weight 400gns.
Barrel twist of 1 : 10
Air pressure 29.6 in/hg
Temp 59 F
70% RH
Muzzle velocity 3000 fps
Bullet length 2.300"
B.C. ?????

Stability factor comes up at 1.44 so it should be stable in most rifles. I would say that the B.C. would be quite high enough to keep most shooters happy so long as the basic design was well thought out.

i.e. a basic standard run of the mill BTHP bullet.

OK so who's gunna build it?
