Load for Henry 45 colt

Loaders:

I started reloading to save money and then continued to expand just cause it's fun. Now I'm finally to the point of trying to create a load to increase accuracy. I recently purchased a Henry Big Boy lever action chambered for 45 colt. At first I thought the gun was simply inaccurate. Was shooting foot wide groups off a rest at 50 yards. Then I let my military trained son in law shoot it and he got groups of a couple inches at 50 yards but he really had to work at it. So the gun is good. So my question is, to anyone out there with the same gun, what's your best most accurate load? I suspect I'll eventually want to shoot a jacketed bullet for deer hunting.

Live well, be safe

I'm using 19.5gr 2400 behind a hard cast 250gr rnfp at 1500 fps. Shoots nice and is accurate.

Thanks

Jim:
Thanks. I'll give that a try. I've read about 2400 in a couple of posts. Must be some good stuff?

Live well be safe

You might want to slug the bore; it may be oversized causing the inaccuracy. Lead bullets should be sized .001 to .002" larger than jacketed depending on the particular firearm. My load is the Lee 452-255-RF sized .452" over 10.5 of AA#5 with a CCI 300 primer.

I have a Marlin in 45 Colt. It shoots the original lead bullets best. I bought a couple of boxes of 300 grain jacketed bullets, as I too thought they would be better for hunting. Groups like you mentioned in your post. The lead bullets are .454 while the jacketed are .451. I bought a box of Cor-Bon 335 grain lead factory loaded ammo that also shoots very well in my Marlin. I am useing Blue Dot as my powder of choice in the 45 Colt.

My bore slugged at .451 and the hardcast are at .452 - no leading has been observed.

I've read that 2400 needs to run at magnum pressures to get accurate. I would tend to believe that based on my work up for this cartridge. I started at 17.5 gr and went to 20.5 in .5 gr increments. It didn't start getting accurate until 19gr. The increase in velocity/increase in charge fell off at 20gr.

With 19.5 gr running a little over 1500 fps, accuracy was good, and pressure signs were well below "pushing it", I chose that load as the sweet spot.

As always, work up loads in your gun based on loading manuals information (not mine).

H4227 looks a bit slower and might be a better rifle powder.

2400, longshot and HS-6 are good pistol powders.

H110 slides right in this range, but I try to use it when other powders aren't quite right like hot 45 LC and 44 mag loads. Probably should give 2400 a look.
