550 Flanged update
well, first, no pictures are this time....

I received my sporting cartridge designation from the BATFE and figured I would drop an update.

the case is a blown out 577/500 case, then trimmed to 3 inches, for a 3.80 oal.

case capacity is VERY close to ~185 grains -10 case average- about the same as the 577 NE, actually...

goal is a 700gr at 2050 or there abouts. sd .331, resulting ME would be 6500ft-lb, spliting the difference in weight OR recoil of a 577 NE. and, well, if you are making a homemade double, why don't make it in your own case

while the project is nowhere near ready for prime time, perhaps in the late winter or spring i'll get some time to work on it.

since twist has been a topic of discussion lately, it is to be a 1x18 --- as that is the twist i speced for the 550 express, and that's the only twist bauska had a button for.

Sounds an awful lot like you need to get one of Tomo577's $400 actions ordered up.

Rich,
thanks... i've got my testing action - a mule, already setup. i am not the world's biggest single shot fan, though it would be a cool thumper

RIP, that is an understatement.

However it is a fun round as the worlds first new Bp Exp. in 120 years. 180grs of FFFg and a 650gr cast bullet.
