They're still a bit of a rare item in the States, let alone here.
Pretty much the same as the 0178, except with a lump moulded into
the bottom of the shot cup to take up space. The few reports I've read
have been satisfactory for guys using WSL & Promo powder in both
AA's & STS's. A couple have stated they're O/U inertia triggers wouldn't
reset with 3/4 oz. loads.
I've tried 3/4 oz. 12 ga. Gamebore (2") loads and found them O.K. on Skeet targets,
but they were less than satisfactory for Trap or anything else much beyond 25 or
30 yards. A three-quarter ounce load just doesn't give much pattern density out at
35+ yards. (Maybe why 28's and 410's aren't all that popular for Trap (yeah, I know,
there's lots that like to play with their subgauges at Trap from time-to-time, and I've done it myself... but always return to the big gun )
With all the R&D that's been done on 24 gram loads and the wide range
of available components .... I think I'll stick with those ! For a factory load,
one of my favourites is the Kent "Velocity International" ... it's a 24 gram load
of 8-1/2's @ 1200. Some very impressive results at Skeet, Sporting, 5-Stand
and Trap, as well as effective on grouse & Woodcock. Minimal felt recoil.
Easy enough to duplicate with common components.
