First of all, you're not going to thrash your revolver. As 45 Dragoon alluded to, these revolvers (Uberti's, et al.) are designed for and chambered in 45 ACP whose pressures are allowable as high as 23,000 psi.

  As to your load with Unique, as others have said, 8.5 gr. is a good balanced load but you can easily go up to 9.0 or a bit more depending on the bullet and how much of it is in the case. (Very important)

  Although I've used a LOT of Titegroup in my .41 Magnum's, I've no experience with it in the 45 Colt. www.loaddata.com points to around 6.0-6.2 gr. as pretty much duplicating the ballistics of the original load (250 gr. bullet @ ~850 fps).

 My personal favorite powders for such loads are Red Dot and 700-X. 6.0 gr. of either will yield 800-850 fps with a 250 gr. lead bullet.

 Uberti-produced firearms chambered in .44 caliber cartridges have a groove diameter of .429". A .430" diameter bullet will work fine in such a barrel.

  With the toggle link actions one has to be careful with their overall cartridge lengths. You can usually get by with o.a.l.'s that are a little on the short side, but if the o.a.l. is too long the cartridge won't feed. If I remember correctly 1.6" is the absolute maximum o.a.l. for the '66's and '73's.

 You could probably work up a load for the 225 gr. FTX, but the simplest thing to do if you must use a jacketed bullet is use a 200 gr. Hornady. My Hornady manual doesn't have a jacketed data for the 44-40 in a rifle, but in a revolver their maximum load with Unique is 9.8 gr.

 If you want to keep things really simple just order something like MBC's 200 gr. RNFP lead bullet. I've loaded a similar bullet (220 gr.) in my 1866 Uberti 44-40 Sporting Rifle with 9.5 gr. of Unique. MV was well north of 1300 fps and the load was quite accurate even at 200 and 300 yds.

 

 The same bullet only with black powder works perfectly for me on whitetail-

I couldn't agree more!  It's actually kind of embarrassing how I excited I get when people I've never met get a new gun!

I got a wide groove analogous to the big lube mold in 44-40 from accurate.

Sold!

Replied to your message. 

This is a neat little SA, great for drills, woodswalking and potting armidillos with cheap steel case 9mm.  I have a lot of this stuff, and even more 9mm range brass if handloads are needed.  These are well timed with what look like Wolff springs.

But what really brings me here is that a few weeks back I picked up a Pietta .357 cylinder from Cimarron, and it dropped right it, no smithing needed, and has shown excellent accuracy with .38 handloads.  Pietta is really making a nice revolver these days.

Quote from: medic44 on Yesterday at 12:58:54 PMI saw the xtp bullet, If was to use the FTX hornady flext tip 225 grn... would i reduce the load if using unique? or keep at 8.0 gr? I dont have to use the flex tip bullet, but I have downed plenty animals to feel comfortable about using it, as I feel its proven itself to me. Thank you

I looked in a bunch of manuals for a 44-40 225 gr. FTX and couldn't find anything. You could call Hornady and see if they have any information for you.

I would definitely reduce the load if working up a load for the 225gr FTX. You could always increase it while watching for pressure signs. With that said I'd still use a 200 grain HP pistol bullet with published load data.
I really like the Nosler 240 gr. JHP and my brother in law uses the Hornady 240 gr JHP in 44 Mag rifles and pistols for deer.

Bought it new from Midway last October.  Still have the box, papers, bumper sticker, and oily bag it came in.  I can get pictures for you Monday, but it looks just like the advertising.

I got it by accident.  I ordered a standard blue, and was shipped this one.  Never been in a holster.  Only shot it to check sights (pretty much dead on with a 255 at 850 fps)  Nothing else I have is Charcoal Blue, so ended up an orphan in my safe.
