This was a cool build, .255 Banshee Javelina

It started as a .44 Mag. Bisley. We had some lightening cuts to the frame done in (4) places, perhaps an ounce relief per spot. Thank goodness. When anyone picks it up they always exclaim at the heft. I didn’t consider it’s basically a solid chunk of steel with tiny .257” holes bored. It weighs 57 ounces unloaded. A bit heavy on the hip it is perfect in the shoulder rig. The 75-80 gr. bullets easily scoot at 1600-1700+ with longer brass life. The Hornet case will loosen primer pockets early if pushed too hard. The heft certainly makes it a dream to shoot with weight dampening the wiggles. It basically has the trajectory of a .22 WMR rifle but twice the power. Old .25-20 lever gun performance.

Toying with bullets and the size of meplat manifests adjustable performance. That is a study in itself.

Nice!

327 Brass

A solution to the loose primer pockets and flimsy brass on the 22 hornet would be using 327 fed mag instead. Much thicker brass, a little higher pressures, and much more case capacity, too. The brass is readily available from starline, unlike 22 hornet. It achieves all of this with a wider body, but because the rim diameters are similar, it doesn’t reduce cylinder capacity.

Of course, this would require a rechamber.

Gary has that in his .250 GNR, however

to keep some distance from the .224-32FA (Bob Baker's .22 on the .327 Federal), and Bob had distant plans for a .25 cal. version. Gary knew this, and did his on the .32 H&R case. Same idea as yours however.

On Bob's .224-32 FA you shortened the neck considerably. I didn't like trimming so I just used .32 H&R to make my FA rounds in one pass. Bob didn't think it was such a hot idea, but I got away with it.

I never did Gary's .250 as I was already invested in the .255.

Plus, I don’t think my platform could house

The larger case head with rims. A six-shot could of course.

If it’s based on a Blackhawk, it caN

The Blackhawk came from the factory chambered in 327 with an 8-shot cylinder.

That said, the ideal platform would be to start with the Ruger single sevens. Incredibly light and handy, even in the 7.5” barrel

That might be something I'd pursue, an extra cyl.

It’s unfortunate the 224-32 got in the way

The 250 GNR is excellent in the bearcat, where the 327 case would be too long. However, in essentially every other use case, the 327 just plain makes more sense.

I did not have an enjoyable experience in .327

They initially came primed with small rifle primers. Which made some loads spike in pressure. I had a near 20% loss rate at first with forming .224-32FA. Best I managed was about 10%. I had zero loss making them from .32 H&R. Taffin concurred my strife as he had encountered the same issues. The brass may have needed some annealing but being brand new virgin who would have thought. Bob Baker did give me some helpful tips.

I managed to take my Muntjac with the FA97 in .224-32FA using a Hornady 40 gr. Varmint bullet at 2150 fps. It still didn't expand much if at all, since it is made to run 4500 fps from a .22-250 or .220 Swift.

Loading as a .257 it might have been different.
