Does anybody have one of these rifles? I wonder how the " fast twist" barrel shoots and what type of 45 caliber bullets work. I love the way the rifle looks and I am considering it for target and deer hunting. How about those target sights? Would they work OK for hunting or would a large aperture be better. A lot to think about but hey, that's what makes this muzzleloader thing fun.
 
I dont know of anyone that has purchased one of these rifles yet. I think you should and report back. It is your duty!

I would suspect that their barrel will shoot quite well. Their Gibbs rifle certainly does.

Give it a go, if you dont like, sell it.

The 'Whitworth' style bullet is a long .451 calibre, multi-gooved or paper-patched bullet of around 450 - 535gr weight.

As the Polisar Brothers have successfully shot buffalo with this calibre, using their own swaged bullets of 500/600gr, I don't think that you have any problem dropping deer-sized animal.

What they do NOT like is any kind of patched ball - the very fast rifling rate was designed to shoot long-range bullets, not short-range ball. And before anybody get the flame-thrower out, short range here means 150 yards or less, and long range means a thousand.

Just in case it slips by, this is not an hexagonally bored Whitworth rifle.

The MLAIC name their competitions, and 'Whitworth' is the name of the 100m prone percussion target rifle match. In this case, Pedersoli use the name to suggest to competition shooters that the rifle is suitable for that event.

Thank you for that information.

I find it rather odd that the name of Whitworth, THE name associated with truly long-range rifle shooting, is being used to promote a 100m/yd match?

Whatever, it's a nice-looking rifle.

The MLAIC held the first World Championship in 1972. For many years matches were only held at short range. It wasn't until 1999 that the first MLAIC Long Range World Championship was held.

This from the MLAIC web site discussing origins of the competition names:

Whitworth
Sir Joseph Whitworth, much celebrated 19th century mechanical engineer (1803 ”“ 1887) who advanced the accuracy of engineering and developed a rifling system for long range shooting.

Peep sights are not the best for low light conditions.

I have shot quite a few deer sized animals with my .451 ML. Works just fine.



hard bullets will blow right through a deer. The picture shows a .50 cal and a .45 cal bullet mold that has been converted over to casting hollow point bullets. These bullets work great for deer sized animals. I only use pure lead for these molds.

With 86 grains of 2 f swiss they are pushing right at 1300 fps.

Christmas is coming, buy yourself a nice present...

Hey Weldon,
All I can tell you is what I know.
So far I've shot fast twist bores in .40, .458 and .52. Each of them uniquely have strengths and weaknesses.

.40 was a mistake in some ways but I live and learn. It was made with narrow land rifling designed for pre-engraving the bullets. That works well as a device to ensure alignment and to limit the amount of expansion needed to fill the grooves. But pre-engraving just isn't an essential attribute to achieving accuracy. And if you use bore diameter bullets then you have maximized the amount of lead you gotta move to get the bore sealed. But speaking of bore diameter bullets for a .40, uh oh, there's not much to choose from unless you go custom.
One characteristic of narrow land rifling in fast twists is that it's nice when you want to shoot patched round ball in the rifle; a tight patch that fills the grooves won't "skip the lands" because it was riding on the groove diameter to start with.
Now that I'm no longer in Texas and Indiana has a .44 caliber minimum the rifling might get recut. But, I already got the .458 bore.

Because of lessons learned...
The .458 was made to shoot lubed as-cast bullets from off the shelf rifle molds. Even better is to paper patch those same bullets and then run them through the off the shelf .457 Lee sizer. Now there's a combo you're just not gonna beat. Lots of molds to choose from. None of that :slap: special order stuff. But the barrel is a standard TC 26" and a longer barrel would be better.
The .52 bore is made to use standard off the shelf fifty (.515 or so) paper patched. And I found a Lyman .515 round ball mold!

So what did I learn?
:2
That I like having a rifle that's pretty fast twist to handle off the shelf molds but not any faster twist than it takes to do the job.
That there's no reason I cannot have a nice side lock rifle that shoots round ball and lubed lead bullets and paper patched bullets.
 
Pedersoli guns are well made and shoot well.
I have a .54 flintlock which is similar in many respects.
The creedmòr sight on this rifle is an early design and although simple is not really siutable for hunting . It could however be easily removed and replaced by a ghost ring rear sight for hunting . Or you could cut a dovetail in the barrel and mount a conventional rear sight .
I cannot advise on a bullet to choose but there are many designs available for .451 .
Have fun shooting .
