Pedersoli Gamma 90 54 Cal Muzzleloader Rifle, 28" barrel

Surprise, Surprise??? !!! Was not aware that Pedersoli, had gotten sucked into the MML (in-Line) market but a sale, is a sale. If you contact Pedersoli, they can provide your with a manual. ....

Generically it's a open ignition, striker fired in-line and most likely, out of production. Faster twist; guessing 1"48. Mostly suited for sabots or Conical. I'm sure it has a removeable breech-plug and it the bore is good, it shoud be a good hunter. Work up your "Shot-String"" and enjoy !!!
I see you got a nice accessory package with it and that always sweetens the pot. ....

Be Safe !!!

I would think the rifling would be somewhere around 1:28 or 1:32.

Haug; You could be right as I've never handled one of these before. 1:48 sounds more marketable. We'll have to wait and see. ......

I have a .54 cal Gamma 9000 with a wood stock, but I haven't heard of a 90 - maybe just a different stock? They're not very common in the US. I put a cleaning rod and patch down the barrel, marked it, pulled it out slowly, marked again, did the math, and determined it to be 1:60, maybe 1:62 twist. An inline with a PRB twist... interesting.

Thanks for the input. If you look closely, you will see that the camo coating seems to be covering up some wood. Other pictures of this model, on the internet, are all showing hardwood. I suspect this the camo is as add-on. I recently worked on a Traditions and some of the "back" poly coating is chipping off and sure enough, the stock is made of some very nice Waknut. 1:60 !!!; did not expect that. !!!

Yeah, I think you're right. Here's what I found!

I wonder how many people bought these things to shoot sabots and wondered why they wouldn't shoot.

Somewhat at a loss here and great information that I found difficult to read. See if you can clear this up a bit. ... ?

I see this listed, in an older Dixie catalog and it states that the barrel is 22" blued, .950 diameter, cut-rifling, .006" deep and 1-32" twist. .54 Caliber, Conical or Sabot ..... Not a preferred RB-Shooter.

$400.00 list,

Be Safe !!!

Not sure what you're getting at but a 1:32 twist won't shoot a round ball worth squat.

David Pedersoli emailed me and said that he made the rifle for a short time as a promotion for Cabela's.

Looks like some range-time, is in order and my compliments on doing, your home work. I may not be paying attention as I'm still not clear on what the twist is. Regardless of the varying features, MM/L's are fairly predictable and pretty much follow the same design path. On this one, I would, physically confirm, the twist. ......

Enjoy and;
