I just started loading my .445 DW. I have new and old brass. I just made a few rounds today. I'm using Win. 296, 29 gr of powder with .300 XTP gr. bullet. The primer is Win. Large hand gun/Magnum.
A couple of rounds shot fine, but some bulged the primer causing it to lock in the firing pin hole. It may not be bulging but being pushed back so that the primer is not even with the brass base. You have to force the cylinder open when this happens. I also shot a couple or empty brass rounds with the primer and sometimes it would lock up. Otherwise with the pistol loaded the cylinder spins fine.
I know magnum primers are thicker than standard primer. I would think the Win. large handgun/magnum primers would be thick enough.
Anyone have a suggestion on correcting this problems? Thanks, Gary

What kind of brass are you using? some 445 brass takes large rifle primers. Most Starline brass is factory set for large pistol only. Difference of .007 in seating depth.

I have a 100 rounds of Starline Brass. How many times can you reload those usually? Plus the 100 I'm getting from you on GB.

I'm still a reloading novice, so I don't have much sound feedback just yet. However, Shoot's got a good point, it sounds like the primers aren't seating correctly, if they're pushing back out of the brass. Do you have a shot of one seated?
I use a CCI350 primer in my Starline .445 brass & haven't had an issue at all, so far.

I'll take a pic. i'm going to make some more rounds tomorrow. I ordered a compensator wrench from EWK. I haven't received it yet. I thought I would take the barrel off and adjust it. It's pretty tight to the cylinder. I shot a .44mag. in it and had no problem. Life is a mystery sometimes.

Shoot is probably all over it. Older Starline 445 was LRP. If it's used brass, the pockets could be soft too- you never know how many times it was already reloaded.
Here's a bit of info on primers:http://www.chuckhawks.com/primers.htm and here: http://www.lasc.us/primerchart.htm
Difference in height of LP vs LR is .01 according to that info.
Depending on the case, I anneal every 5-15 loadings. Straight wall cases last longer between annealing, unless you only neck size the bottle-necked cases. Of course on the less expensive cases, I just keep an eye on them for cracking and then toss them. I also trim when they get too long for the chambers. There are a lot of variables that determine case life.
My best advise- get a reloading book and read the information. Too many folks just use the recipies; at least I did when I started reloading. Things become much clearer when you read the technical mumbo-jumbo.

OK! Now I'm cooking with grease. I went back and meticulously reset my dies to precision. I'm using 28 gr of Win 296/300gr XTP bullets. The Win. Large handgun/Magnum primers worked fine.
I did test my primer on an empty brass. They shoot about a 3 ft. flame out the barrel. I would think they are more than enough to fill the .445 case sufficiently.
One thing that I did different was that I put 6 rounds in instead of just one. I'm new to the Super Mag like this. One round shouldn't cause it to stick should it?
I do have a 357 Max. No trouble with that. Thanks guys for the info. I'm happy now.

No, one round shouldn't stick.
On a side note, I have only fired an empty brass with primer once...scared the hell outta my cat.
That one empty case was fired in my Ruger SBH .44, and it locked that darn thing up "right now". I had to do a real funky disassembly procedure to get that cylinder apart.
I didn't do it again.
After I got it apart, I noticed that the primer (as I suspected) had jumped & locked the cylinder's rotation. Being a reloading greenie, I just assumed that firing a primer in an empty case is simply a no-no & haven't done it since. The same primer in a loaded case fires flawlessly.
I'm not gonna question your reasoning behind firing multiple empty cases, only to say that you may have been lucky thus far. I'd probably look at snap caps for my dry firing needs.

I wasn't firing multiple empty cases. Just one. I was loading the cylinder with only one fully loaded cartridge and it was sticking sometimes, but with 6 fully loaded rounds it didn't stick. I dropped my powder load just a bit and it seem to work fine. I'm using those large handgun/magnum primers. We live and learn as we tinker with things.:)
