44 Lasercast 240's

[LOLBELL]

Anyone have any data for Lasercast 240 LSWC with IMR4227? I've loaded a lot of lead with Unique, but these have a BHN of 24 so I'm wanting to push these a little harder than what I normally push a lead bullet. And by the way I have Serria, Speer, Hornady and Lyman Manuals.

LOLBELL,

You got those from me.

When I was shooting those out of my 6" 29-2, I used 8.5g of Universal and took 2nd place in our club. At 50 ft I could put 10 rounds inside of a 3" circle. I did get a little leading, and you're right, those harder bullets like to be driven a little faster to seat in the barrel.

Nowadays, I'm enjoying my 1911s a little more. Saving my wheelguns for my son to shoot. He's only 8 and he's already calling them "his".

Ooos, should have read closer, never used H4227 for those, but I have used it for 240g JHP bullets in 44mag.

Only speaking from memory, shouldn't 19 to 20 grains be a good place to start?

 

[LOLBELL]

I've not found any data at all for IMR4227 and lead. Lasercast says jacketed speeds, which with this powder would be about 20 to 22 grains. LC has a manual now but I hate to buy it for one load. By the way those bullets shot several 6" groups at 100yds out of a scoped Ruger SBH Hunter with 9.5 of Unique yesterday. Off of sand bags ofcourse. I like those bullets.

I have a Laser Cast Manual, but it doesn't list that powder. It does list the following though if you have another preference,

HS-7 and 7, Unique, AA-9, H110, 296, and 2400. If your not in a rush, shoot me a PM I will throw some data your way. Might be later on tonight or tomorrow though.

To be honest with the ones I have shot I simply loaded them over what I had the most of on hand, which was usually 296 or A-9. I worked them right up to magnum velocities with no ill effects in my Redhawk. I have also run the .357-158gr up to top end as well out of my GP-100.

Just make sure you get all of the copper out ahead of shooting them however as once they start to foul they get the job done quick, and it's a pain to scrub out.

Good luck and hope this helps.

Glad you like them. Glad they're getting used. I looked but can't find any load for H4227 and Lead. But as the general rule goes, you can substitute a lead bullet in a jacketed load recipe, but not the other way around. I'd say start at 20g and go from there. Keep us posted.

Disclaimer - your gun may blow up, do not use these listed loads, etc.

Lyman shows a 240gr @ 1.645 oal iwth min at 21.5 and max at 24 for IMR 4227. I've used this as a guidline for years. That's what I target shoot and hunt with out of a S&W 629 Classic with 8 3/8" barrel.

23gr zips them along plenty for me with no sign of leading and no gas checks used.

Thanks, bangbig, I did not see anything in Lymans for Lasercast bullets. Will work up somthing though. I really like these bullets

There is data for IMR4227 on Hodgdon's online load data site. With a 240 grain cast bullet, they list only one load, 22 grains of IMR4227. This is a slightly compressed load. I've shot this one under a 240 grain lead truncated cone bullet and it is pretty accurate. I bumped the charge up half a grain and it was a little better. They list 24 grains as top for a jacketed bullet, so there's a little room to go up. All of these loads are compressed, so be aware of that.

Also, the IMR4227 one buys now is actually H4227 powder, in an IMR can. They discontinued the IMR powder, discontinued the H4227 label, and put the H4227 in the IMR4227 bottle and called it IMR4227. Confused yet?

 

[bangbig]

Yes, depending on your bullet, you may be in compressed load range. They Lyman loads were not specifically for Laser Cast. But I have used The lasercast SWC's as well as other lead SWC's without issue.

As always, start low and work up.

23gr is very accurate and deadly on deer for me.

Hammerdown77, thanks for the info on the IMR and H. It's been YEARS since I've purchased any. 8lb jugs makes quite a few 44mag loads for a plinker like me.

 

[LOLBELL]

I too thank you Hammerdown77. I have at times found data for H4227 but not IMR4227 and have wondered if they were the same powder and data could be interchanged like 110/296

That's a tricky question and one I've not investigated further myself. At one time H4227 and IMR4227 were different, and had different burn rates, and the loading data reflects that. I don't think that you can substitute them both like you can W296 and H110. Or maybe you can.

A call to Hodgdon on that question would be your best bet.
