Store Bought Oversized 44 Mag Cast Bullets.

[tkcomer]

I have a 44 mag Rossi levergun that has an oversized bore. Best I can tell, it slugs out to around .431 or .432. Does any of the major companies make a cast bullet that size? Most of the ones I've found make extremely heavy bullets. Trying to stay 240 grains or smaller. Any help would be appreciated.

I believe that if you contact Brad at Missouri Bullets, he will size bullets to within the range the molds throw them. I doubt you'll get .431" or .432", but I would bet that .430" would be no problem at all. Contact him and see what he can do for you. Here's the link: http://www.missouribullet.com/index.php Just click on the "contact us" link from there.

I size all my cast bullets in .44 at .430", and there is still some sizing going on. I'll have to measure some and see what the actual diameter is as they fall from the mold. I shoot mostly 185 gr. cast bullets through mine, but swage 230 grain jacketed bullets and they're all .429".

Hope this helps.

We can indeed size to .431, no problem.

I can do .432 no problem.

Boy, you guys are quick!

There you go, tkcomer. You have at least two choices now.

Hope this helps.

Beartooth Bullets does custom sizing also.

Years ago I had the same problem with a Winchester 94 in .44 Mag. I solved my problem with Super Grex. Too bad it is no longer made, but there are alternatives like PSB.

Wax gas checks work great too, but are a pain to do.

Sounds like you'll be able to get them the size you want, so no worries.

I need at least .431. .429 plated bullets shoot shotgun patterns out of this gun. Jacketed bullets shoot fine. Right now, 200grn .431 Laser Cast bullets shoot OK, but they are too hard. They lead the barrel about 3 inches from the chamber. Then again, when I slugged the gun, it seems to get tight in that area.

 

[Walkalong]

PSB will stop that. So would a wax gas check, but as I posted, they're a pain.

As you have surmised, leading just in front of the chamber is usually from too hard and/or too small of a bullet. Sounds like both. Try a softer .430 bullet that will bump up under the pressure you are generating, or even better, get some softer .431 bullets from MB or .432 bullets from Penn to try.

I would highly recommend the Penn Bullet. My redhawk requires .432 and i have been very happy with Penn's.

I can do .432 no problem.

We can do .433, no problem.

Haha, no we can't, I'm kidding!

I read this recently and just went to the SAAMI site to confirm, the groove diameter specs for the 44 mag in a rifle are .424 bore, .431 groove compared to .417 bore, .429 groove for a revolver.

Seems like trying to use revolver data in a rifle could be problematic. Perhaps your rifle is not "oversize"?

 

[tkcomer]

Now why the heck would a rifle and a pistol have two different specs in 44 Magnum? And what I've "heard" is the early Rossi rifles were all over the map in bore sizes, but the later models all come with the "correct" .429 bore. This is from Steve Young, who knows a just a little about Rossi rifles. I have some of his parts in two of mine.

I've never heard of the Marlins or Winchesters having this problem.

Initial Range Report on MBC 240 Smashers

Great weather here in Atlanta today, 75-80 degrees, 10mph breeze.

Continuing to work with Blue Dot in the 44 Mag with the 240 gr MBC .430" Smashers
All loads, Starline Brass, CCI Large Pistol Primers, 1.566"

Loaded up some with 14.0 & 14.5gr Blue Dot. Didn't get a chance to run them across the chrono yet, as I was tied up up shooting 357 Mag & 30-30 MBC bullets.. but I did fire off (2) 3 shot groups out of my Marlin 1894 44 Mag with a 4x32 Simmon scope.. yeah, not a very powerful or great scope, but seems to do the job at 50 yards, I'm pretty sure I could make a good shot on a deer out to 100 with it.

I think I'll have to order up some more of these bullets, at just under 1/2 the cost of Hornady XTP HPs.. and preliminary accuracy seems solid. Will probably try some a little milder, maybe 12.0 & 13.0gr BD, or perhaps some with 2400.

50 yards, 14.5gr Blue Dot, 4x scope
