Ok Slash, once again Randal is correct. Yule of thumb is one caliber for the depth, and he is also right about those numbers aren’t quite right for the larger calibers. It sounds like the xtp might be a little shorter than the FMJ’s. I normally seat my shorter .4515 bullets to a depth of .187” with no ill effects at all, your number of .166” is a little skinny, but hey, try’em, but get that OAL out there a bunch more, someone quoted a 2.017” OAL and that’s simply way too short, probably works great, but, the shorter the OAL the more the pressure. ; H110 is interchangeable with the data for WW296 and is a great powder for the 450b as is 4227, but AA1680 will keep the speeds up there and lower the pressures.
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!
