I need a decent load for this setup. I know it's not an ideal combination of powder/bullet, but I have a lot of both of these and I can't find any load data for this combination.

I'm looking for anything from 1200-1500 FPS ideally, but I'll take whatever I can get.

Thanks,

Mike

Without gas checks pushing a lead bullet over 1200 fps is going to lead the barrel badly, especially with a powder like H110.

The reason you can't find data for that combination is a good one. They just don't work well together. May I suggest trading off the bullets for more appropriate bullets for the caliber. I'm sure you could make a deal with a .45 Auto reloader.

Good luck finding the data, I looked as some of my sources and can't find anything to help you, sorry.
Closest I came to matching what you are looking for is:
250gr LRNFP Laser Cast bullet
22.0gr H110
CCI-350 primer
PMC brass
COL 1.600"
tested 1267 fps no barrel length listed
Marked Ruger T/C only!

I agree that is a marriage made in hell.

H110 needs high resistance from jacketed or heavy bullets & the accompanying high pressure to burn properly.

Your light for caliber lead bullet will slip through the bore like a greased pig, leaving behind inconsistent ignition & unburned powder.

If you want to shoot the bullets, you need faster powder.

If you want to use the powder, you need heavier lead or jacketed bullets.

I will respectfully disagree with that sentence.

Last Friday I shot the following loads in my Ruger Redhhawk:

250gr Oregon Trail LRNFP
H110
10 @ 21.0gr*
10 @ 23.0gr*
10 @ 25.0gr*

300gr Oregon Trail LFP
H110
10 @ 21.0gr*
10 @ 22.0gr*

And the following loads in my Marlin 1894:

250gr Oregon Trail LRNFP
H110
10 @ 18.0gr**
10 @ 19.0gr**
10 @ 20.0gr**

All of these loads have velocities at or above 1200fps (according to my reloading manuals) and yet I didn't have any leading in either barrel.

I did get severe leading using 10.5* and 11.0* grains of W231 and an Oregon Trail 200gr LRNFP bullet but rcmodel et al set me straight on that one.

WARNING: These loads are NOT intended for Colt SAA revolvers or their clones. These are intended for Ruger Blackhawk, Ruger Redhawk and the modern Marlin 1894**

1858,
What's to disagree with? The OP didn't tell us who's bullet he was using and what the hardness is. As a general rule if you are going to push a lead bullet from 1200 to 1500 fps with a powder like H110 you WILL get leading. On the other hand, using bullets with a BHN of over 20 like you are will of course be fine at those velocities. As a matter of fact if you don't push bullets that are rated that hard you can get just as much leading as pushing soft bullets too fast.

I wasn't wrong in what I said and your examples are different from what I'm talking about. Also, are you really trying to tell me the velocities of your rounds were 1200+ fps because that's what the manual told you? Until you pass them over a chrono you can't know what the true velocity is. If the book claims 1200 fps you're lucky to get 950 fps. IMHO of course.

Let me rephrase my post above to say that I didn't get any leading using the lead bullets and loads listed with H110 powder. Let me add a couple of comments re the velocities though. The Speer manual lists the velocites out of a 7-1/2" barrel with a 1:16 twist as 1125fps (18.0gr H110) and 1245fps (20.0gr H110). I shot those loads out of a 20" Marlin barrel with a 1:16 twist so I would bet that the velocity met and most likely exceeded the listed values ... but as you mentioned, without a chronograph I don't know for sure. I do now have access to a chronograph and for my own interest I'll get some data.

The other loads were shot out of a 4" barrel also with a 1:16 twist. The 250gr loads were over the max. listed values by 1.0gr, 3.0gr and 5.0gr so I'd be fairly confident that they were also at or above 1200fps. The 300gr loads (based on John Linebaugh's data) were probably very close to 1200fps since he uses a revolver with a 4" barrel but shoots a 310gr bullet.

Good stuff!!
