FWIW; I own and shoot a Penn. Longrifle from Pedersoli in .45 cal.
I would imagine they are about the same, if not the same, as the Pedersoli / DGW rifle.
Mine is approximately eight years old and I have owned it for about five years, IIRC.
At the time I first saw it, a new one was selling for about $800.
I first saw the little rifle at SportCo in Fife, WA where it was on sale for $710, and I liked its feel, its balance.
I went back there several times to look at it, and then, when I finally made up my mind to get it, I went back and the darn thing had been sold.
At that same time, for me to order a new one from SportCo, or Tri-State Sports it would have cost me, with tax, shipping, or whatever else they could dream up close to $900 maybe just a few bucks more....which was well over my head.
Dixie was not offering the gun at that time.
To get the gun I ended up trading a 1861 "Signature" Colt .58 cal.Musket for it to Hawkeye here on the forum. Hawkeye said it had less than 50 shots fired from it, so it seemed a pretty fair deal.
Having never looked back on that trade, I have no regrets. I shoot the .45 a lot more than I did the Musket.
The twist is 1:48, eight grooves, and with RB and Patch, using 70gr Goex FFFg, Hoppes #9 lube, I get an honest 2,050 fps across my own chronograph, with a standard deviation of 36 fps.(according to some old notes.)
For "punchin paper" 45gr Goex FFFg seems just fine.
Typically I prefer something bigger, with a .58 or .62 caliber loaded heavy being my choice.
Although I do own these same calibers and shoot them on occasion, I still prefer the accuracy and handling of the little .45.
Two or three years ago a fellow TMA member, ShadowHawk and I, spent a morning on the range with my little .45 cal Penn. using that load of 70gr FFFg.
I shot about 30 rounds from the bench at 50 yds and about 20 rounds from 25yds with the Penn rifle.
At the end of that shooting session I discovered my right shoulder was literally black and blue with a smidgen of yellow and purple thrown in for good measure.
IMO, this little gun is a great "off-the-shelf" rifle.
I suspect I have fired no fewer than 400 rounds through mine, and I learned early on that it is NOT a bench rifle.
For off-hand or supported shooting the little rifle would be hard to beat for Deer hunting, and maybe even Squirrel, although I'm sure many Squirrel hunters will shake their head at this notion.
Here in Washington State the .45 cal is legal for Deer, so if you plan on killing anything other than paper, small rocks, or dirt clods, you may want to check your Game regs. But then again it may be offered in larger calibers now that DGW is in the game.
Either way, I feel sure you will like the feel and balance of this gun.
Sorry for ramblin so much....
