44 mag help!!

Im just getting into this calliber so im clueless as to why some of the bullets come in .429 and some .430 and what the differences are. any help!

Almost all of the Jacketed stuff will be .429 while most of the lead projectiles will be .430, .431 or even .432 some guns like the slightly thicker bullets and will lead up more or less when switching between different OD's. Likewise there will be accurassy variations as well.

In cast bullets, the larger they are, the less they will lead the barrel.
The limitation on lead bullet diameter is that the loaded rounds need to chamber and the bullets must fit through the forcing cones in the cylinder.
Revolver specialist gunsmiths will often open up the forcing cones to allow for larger diameter cast bullets to be used.

As the above posters said, .429 is jacketed and .430 lead. For the most part. Personally I like gas checked lead for magnum revolvers. It makes a great looking bullet, and depending on the size will pack massive punch, and is generally more accurate than jacketed as the larger diameter bullets grab the lands and groves better. One important point however, if you have a lever action say a 1894 marlin it is picky with the type of loads you build. I would use jacketed bullets for the marlin to prevent lead buildup in the action.

+1 for jacketed or plated bullets for Marlin. I have an 1894s in .41 Mag. I called Marlin and they said with the micro-groove barrel to only use plated or jacketed, no lead.

thanx everyone for the advice!

Marlin is not quite explaining the facts.
Hardened lead, sized correctly,.001"-.002" over the groove diameter, works wonderfully. This fact is well recognized among cast bullet reloaders using The Marlin Micro-Groove rifles.
For the 1894S, cast lead (wheel weight + a small amount of tin solder) gas checked bullets, dropped from the mould at .412" into cold water; or else sized to that and then heat-treated at 425 degrees F for one hour and then quenched in cold water will be at about 19 BHN (Brinell Hardness Number) and will not lead the bore using a bullet of appropriate design, like the 260 gr Old West Bullet Mould.
Actually, the heat treating may even not be needed when using wheel weights + tin with this caliber's velocity and when using a gas check. That's just an extra step I take.
With my 19894S, sitting at the benchrest, I get 1.5" groups at 100 yrds.
Velocity is about 1400 fps.

Hmmmm. Thanks for the knowledgeable input. I am using Rainier 210 gr. FP bullet. Your accuracy is a little better than mine. I am loading mid 1300's. I have a small Nikon 1X6 (?) scope on it and I can watch the hits on steel.
Nice little rifle.

I just checked on Handloader website and that issue is not available. I'll call my buddy. Thanks.
