WW296 and H110 are Ball-Powders and their data is interchangeable and not AA1680 (also a ball-powder), which is a much slower powder. As always in matters of reloading you are on your own and anything you read here should be taken with a grain of salt. Your caution is commendable but be very careful with reduced loads. I consider your load with 37grs of 296/110 to be just on the good side of low, you might see speeds in the 2000/2200fps area, but increase the OAL if you can (2.250”). Keep in mind Slash’s 45gr load, according to the picture record he provided for us, had no problem with pressure. 37gr of 1680 is definitely low and possibly dangerous. Watch for sooting down the sides of the case, if you see it the case is not sealing, because pressures are low in the chamber and of course at that moment increased bolt thrust could become a problem. I would definitely start with 45gr of 1680 with your 240gr bullet. Funny thing, RX7 is the next logical slower powder than 1680 and if used in the 450bthe speeds drop off 500fps, you just can’t get enough RX7 in the case. Good luck…t

Basic Handloading

Great information Wildcatter! I was beginning to think the 450B wasn’t such good choice for a relative newbee to reloading such as myself, but now I can see that this gun might be worth sticking with!

I’m still not sure I want to keep messing with the 284 cases, of the 200 I started out with I’ve only got about 60 left that I haven’t screwed up in one way or the other. I initially bough 200 rounds of factory ammo, of which I’ve fired about 150 and repeatedly reloaded, I think I’ll stick with them.

I still have a bunch of questions related to loading these things, regardless of the case, that I hope you might be willing to help with without giving away the keys to the castle, I’d like it handed to me on silver plater, but I’m new and I realize I still have to earn my spurs.

I’ve got about 150 Hornady 240 gr XTP/MAG Bullets. If I seat them to an OAL of 2.2″ I only have .166″ of bullet in the case. Is that okay?

I also have a butt load of Hornady and Zero 230 gr hollow points that I load for my 1911, it sounds like these hollow point pistol bullets should stay in the 1911 and I should invest in FMJ’s for the higher velocities of the 450B.

For powder I’ve got 4lbs of H110 and 1lb if IMR4227, am I barking up the wrong tree? My goal is two basic loads, a range round for punching holes in targets out to 200 yrds and a hunting round for punching holes in pigs. The H110 @ 38 grs has given me velocities around 2100 using the 240 and 230 gr bullets, but the accuracy sucks, I figure I can afford to play with those as target loads because they are relatively cheap, but I want to use Barnes X 250 gr 454 Casull or Barnes X 275 gr 460 S&W for hunting pigs and they are pricey bullets to be experimenting with. I’m hoping this is where you can save me some grief, will the 110 or the 4227 work or should I not bother playing with them? With the very long 275 gr barnes X the case is pretty much packed with 38 grs of H110 and an OAL of 2.225″. Can I get there from here?

I apprieciate the help, too bad you don’t live down the street!

The Hornady XTP

No, about 2.1″ AOL. Just to where the groove in the bullet starts to hit the case. Don’t ask me why there, it just looked like a good spot, and it gives the roll crimp die a little something to work with.

Like I said, I’m winging this whole thing.

As far as the 284 cases, I’ve had no luck at all. I’ve sized them but I can’t get the case wall the right thickness. A .452 reamer takes to much and leaves a good size shelf down in the case. I’m sure there has got to be a way to make them work but I’m not patient enough.

I’ve just been reusing the brass from the factory rounds. Thank goodness for straight walls, the cases are holding up well.

Montana Gold has some .452 250 gr 45 Colt bullets for a reasonable price, I’ve been thinking about getting some of those, but so far between the Barnes X 250 and 275 gr HP bullets, the Hornady 230 and 240 gr HP bullets and the Rainier 250 TMJ bullets I,m just confusing myself trying to figure out the loads.
