another reloading Question

Howdy folks, as you can tell I am new around here, but I already read just about every post on here over the last couple of months.

Just got a Uberti Cattleman in 45 Colt.  I needed something that left bigger holes in the target then my Single Six :)

Anyway, going back 20 years ago, I used to reload around 400 rounds per week in 38, 357 and 44mag, then I got out of shooting when I met my wife to be and sold my press to a friend who was going to use it.  Now that my Daughter is getting older, I needed a new hobby so I joined the local range and started getting back into Single Action Shooting.  My range does not have CAS shooting, but they do have cowboy silhouette, which will be enough to keep me busy for a while.

Now around to the question:  I know the common answer here is to read all the books, and I agree.  I already know what kind of loading gear I can afford, but my question is powder.

For starters, I will be using smokeless  What powder would you recommend I start with? 
Also what bullet weight would you Recommend for starters? Since I would probably buy 1000, where should I start?

There are so many choices of powder; I figure I would get a recommendation on what flavor to start with instead of just picking one and wishing I had started somewhere else.


PS: The dark side will come, I just want to practice reloading some before I switch :)

   Greetings, CW!

   Since you have prior experience reloading, You just need to get some reloading gear together, or use a buddy's set-up. Be sure to get the latest LYMAN Reloading Manual, too!
   I love the .45C {Almost as much as I LOVE the .38WCF!!!}, and my favorite powder for factory and ever so slightly warmer handloads is Alliant UNIQUE with a standard Large Pistol primer. This is pretty much the standard powder for the .45C, the .44-40, and the .38-40, and it simply works perfectly for that cartridge power level. Although I don't like giving charges, I've found that 8.0 ~ 8.5gr. of Unique is perfect; however, take note that MY CHARGES ARE MAXIMUM or NEAR MAXIMUM in LYMAN and some other reloading manuals... Start your powder 0.5 ~ 1.0gr lighter!!!
   Since I cast my own bullets, you'd be better off asking around for good deals on store bought lead bullets; one thing you DON'T WANT in the .45C {Loaded to Standard Colt SAA levels!} is Linotype, or some other HARD lead alloy. I will almost guarantee You that your Cattleman .45C will shoot wonderfully with SOFTER lead bullets of .454" diameter {NOT .452"!} that will fit your sized & belled .45C brass Very Snug.
   Keep Us posted on your progress, and Welcome Back!

   Be Well!

Thanks M.T.  I was thinking Unique, but I want to here from the folks that already are reloading.

as far as bulllets, I am still educating myself on them.  I have to visit the local reloading store and see what he has.  I was not sure on the size. So .454 is what I should run through the Uberti?

I've recently switcvhed all my reloading for CAS to Trail Boss powder. It's a high-volume smikeless that is easy on the hands and equipment even at full boat loads. More accurate to boot. I load Bear Creek bullets. In my pistols, the 205 gr RNFP moly 45's shoot at POA with no fiddling on the sights. As to brass, I recently started oading the Cowboy 45 Specials that Adirondack Jack makes and sells. they're even more accurate than the 45 lc cases because of the more consistent burn you get with a smaller volume case. Great results with both. I've been using the bullets for years, but the cases just came out and I'm a convert.

My load is: C45S cases, Win std/mag primers, 4.5 gr Trail Boss powder, 205 gr RNFP moly BC bullet.

First some comments about 45 Colt and bullet diameter. I'm going to paste something in here that I wrote over on the SASS Wire a few weeks ago, to save retyping:

*******

It depends on the diameter of your chamber throats. Chamber throats can vary from manufacturer to manufacturer and gun to gun.

You probably do not have to slug your barrel, most 45s are pretty good at holding the standard .451 groove diameter. Although slugging a barrel is really easy.

Typically, bullets for 45 Colt are available in two diameters, .452 and .454. The .454 size is really for pre-WWII Colts that had barrel grooves of .454. After WWII 45 Colt barrel groove diameter was changed to .451 to match the diameter of the 45ACP cartridge.

Determinging the proper size bullet for a 45 Colt revolver you actually have to work backwards. Most important is the diameter of your chamber throats. Ideally you want your bullet to be the same diameter, or just .001 or .002 smaller than your chamber throats. Any smaller and gas will blow by the bullet before it leaves the chamber throat, causing leading and possibly upsetting the bullet before it reaches the forcing cone. Ideally, chamber throat diameter should perfectly match the rifling groove diameter. Unfortunately, revolver manufacturers have not always done a great job of matching up chamber throat diameters to groove diameter. My Rugers are right on the money at around .451-.452. My Second Gen Colts are typical of that Generation in that they have oversized throats, around .456 in diameter.

Here is a simple test you can do if you can get a couple of sample bullets of the two different diameters. Remove the cylinder from the gun and hold it vertically with the chamber throats down. Take a bullet and drop it into a chamber. If the bullet drops right through it is too small. If it hangs up in the throat and can be shoved through the chamber with light thumb pressure, it is ideal. If you have to really shove it through, it is probably too large. Be sure to try all 6 chambers, they can vary, even in the same cylinder.

With oversized chamber throats, .454 bullets are a good option. They well seal better in the throat than a .452, and will get sized down to .451 in the rifling. This is not a pressure problem as long as bullets are reasonably soft and loads are moderate. With chamber throats that are closer to spec, like my Rugers, there is no point to using a .454 bullet and .452 should be fine.

*****

OK, that's the scoop on bullet diameter and 45 Colt. If you can get a few sample bullets you can determine what your pistols need. Personally, I shoot .452 in all my 45 Colt revolvers, including my 2nd Gen Colts with their oversized chamber throats. I shoot Black Powder and cast my bullets very soft, so they probably bump up in diameter when they leave the case.

Might as well talk about bullet weight for a moment while we're at it. The traditional bullet for 45 Colt is a 250 grain round nosed bullet. That is the bullet the cartridge was designed for back in 1873. In the world of CAS, shooters who are concerned with shooting fast often try to minimize recoil with the 45 Colt by down loading it. They often attempt to recreate 38 Special ballistics in the 45 Colt. The 45 Colt does not do this very well. 45 Colt was originally designed as a big, powerfull man stopper. It does that very well with a 250 grain bullet and a stout powder charge. Part of the problem is the huge case capacity. The case was originally sized to hold 40 grains of Black Powder. Once Smokeless is put into it, the charge occupies much less volume than the original 40 grain BP load. This means there is a lot of empty airspace in the case. Lots of empty airspace can lead to poor ignition and inconsistant burning of the powder. Couple that with a light bullet, and powder burn can get even spottier. Some CAS shooters have migrated down to very light 160 grain bullets in the 45 Colt in an attempt to lessen muzzle flip. Personally, I have found that 45 Colt works best with bullets in the 230-250 grain range.

You mentioned you are going to be shooting Cowboy Silhouette. I dunno what range you will be shooting at, but I suspect you will want a stout load.

My own standard Smokeless load for 45 Colt has always been 7.5 grains of Unique and a 250 grain Round Nosed Flat Point bullet. This is a bit under the max, but it still generates enough pressure to work well in the big cavernous 45 Colt case.
