I have a new mgm 12 inch 45lc barrel on a g2. I been playing with 250xtp over hogdon minimum charge of 23.5 grains of lilgun. They published a velocity of 1333. I have a new magneto speed which is reading at 1650. Does this sound right? I do know that it’s not much fun to shoot and I need to step it down a notch. I think I bought the lilgun and h110 to try with this piece. What powder should I look for to calm this down some?
I’ve burned about 3 pounds of lil gun in a number of cartridges, and I’ve found it to vary greatly in its burn characteristics, with velocities and pressures all over the map. Others experience has differed. H110 has been very consistent for me, but is most predictable at near max loads. If that’s what you want, I’d give H110 a try, making sure to have a good consistent crimp and magnum primer. If you want less than full speed, I’ve found 2400 to be good at less than full charges, as well as at full speed. Good luck!

I just looked I didn’t buy 110. I think I’ll keep an eye out for 2400
What do you want to do? If target shooting or cougars out of a tree @ 20 yards or less 6,5 gr Red Dot and a 240270 gr bullet just works. It gets about 950 fps out of a 4 5/8" blackhawk and is accurate out of my 10" contender. If you want to hunt look for some AA9, 296. H110, or 2400. Blue Dot might work as well.

If you’re finding the H110/WW296/Lilgun level hotter than you want, the 2400 suggestion to slow things down a bit is a good one. I’m posting because AA#9 is very similar and often a little easier to find and somewhat cheaper.
I want to use the 45 for whitetail range most likely 50 yards like to be able to stretch that some if I can see that far. I guess I’d like to try something around 1200 fps.
Get some 2400 powder if you can. It, and IMR 4227 are excellent powders for your applications.
I have a Contender barrel for 45 Colt. The lightest of the factory barrels (Octagon - external choke). Full power "TC / Ruger" was brutal. With a 12" round barrel, 1200 fps should be a lot more comfortable to shoot.
For the 1200 fps you desire, 2400 is a lot slower than needed. All of the Quickload calculated loads are well below the 30,000 psi limit for the Contender. Faster powders will minimize muzzle blast.

Even though the 1200 fps speed is probably enough, I would try a few a little hotter just to see how both you and the gun like them. I ran the previous table up to 1300 fps for your reference.

That’s a lot of good info right there!
I ordered the barrel with mgm’s sixer brake and it was still nasty to shoot with the lilgun . I think I know where to get some #9 and keep my eye open for 2400. I appreciate everyone’s input
What's the length of barrel Hodgdon used to get the 1333 fps and was it out of a revolver?Originally Posted by Catmanran

I’m not sure what hogdon used I went back and looked didn’t see it on the page
So to follow up the only powder I could find locally was imr4227. I loaded a handful at the minimum charge and clocked at average 1,118. Seemed like it might group well. And it much more pleasant to shoot. I’ll play with that some more. Had a single cartridge loaded with the lilgun figured I get rid of it 1,670 on the meter
I pulled up a Hodgdon dats sheet online with 23.5 as starting charge and listed barrel length was 7.25"
That was probably a revolver or a vented test barrel. Having numerous Contender barrels and revolvers in the cartridges, including the 45 Colt, I have no doubt that 1650 fps is a correct velocity out of a 12" contender barrel. The differences in velocity obtained, with the same load, in revolvers with 4 to 8 3/8" barrels vs Contender 10" or longer barrels can be as much as 200 - 300 fps.

I know you mentioned you were loading a Hornady XTP, but for the sake of this forum, it’s hard to beat a Keith Style bullet over a generous load of 4227. For some reason, the 45 Colt and 4227 combination are easy to work up accurate and powerful loads. It won’t push a bullet as fast as H110 will, but H110 is a hard powder to get to shoot for me. If you do get and load it, I strongly recommend a heavier bullet, a heavy crimp and magnum primers to minimize chances of a squib load. As noted, 2400 also works well. Count yourself lucky you didn’t get H110
I loaded up some more with the 4227 but haven’t had the time to continue. Little time I’ve had been working on a friend’s muzzleloader
For 99% of my big bore handguns,, I use a total of (4) powders. I use Unique for what I call "fun loads!" But for serious shooting,, and finding the best accuracy,, I use 2400, 4227 & HS6.
But a Contender can be a different beast occasionally. However,, I still do not use H110 for much. But even in Contenders,, for the 45 Colt,, my "big 3" have proven their performance. As always,, accuracy trumps velocity.
Well I got back at it and found 22.9 grains of imr4227 puts me about 1235fps. And looks dam accurate
WINNER, WINNER, Chicken Dinner!
Very good find!
