I don't know of anyone who has tried that heavy of a pill before.

You might want to use the search function on the forum here to look for the previous discussions and trials of cast boolits in the 450b before you launch any...its turned out to be something of a mixed result, at best...jus' sayin'...

randyf-

Cast projectiles have been discussed continuously on this forum. Here are some of the threads, some of them with the information you need to get started, and some discussing the problems you will encounter. Some of the titles are deceptive and seem unrelated to cast bullets; read them and find otherwise.

• Cast Boolits in the .450B #1
• Cast bullets #1
• Cast Bullets and the 450 Bushmaster
• Loading Lee C452-300
• Gas Checked Lead Bullets ? #1
• Some Cast Bullet Trials - A Joint Project
• Cast Bullets #2
• Unjacketed Lead Bullets for the 450
• Cast Boolits in the .450B #2
• Gas Checked Lead Bullets ?? #2
• Sub-Sonics
• Brass
• Gas Checked Lead Bullets ? #3
• .454 or .452
• Cast Boolits? #3
• 450B taller gas checks
• Reduced Loads

Some of the threads have the same titles, but different questions, answers, and discussion.

Cast Performance bullet advertise 3000fps possibilities, without leading the barrel. You may have some minor accuracy problems with the gas checks, maybe/maybe not, shoot'em and let us know.

For any bullet heavier than 275gr, AA-1680 is the better powder, for over-all performance (generally, more speed with lower pressures). You can use lil-gun, but the pressures will peek quickly and leave allot of speed, on the table, that 1680 would otherwise pick up, and you still won't hit CP's 3000fps bullet max. With bullet that heavy even RX7 could be a good choice, which is somewhat slower.

Lil-Gun and 395's could make a pretty decent plinking load..

I was going to pick up some AA 1680 for some jacketed bullets I was also loading.

From what I read the 395gr bullet gives better accuracy at lower speeds ( don't know if its true or not, because I have not shot any yet).
About how much 1680 should I put behind the 395gr pill??

What?!
300+ grain bullets going at 3000FPS? Out of a 450 Bushmaster?

Boy, I don"t know.

Are you familiar with my method of ascertaining how much powder is maximum?? Short Form here, and you'll have to be the Arbitrator, as to what's safe. Using a 1/4"drill drill, drill out the primer pocket. Seat and crimp, the 395, for a dummy round, to the correct OAL. Fill the case to the cartridge head, with the powder of choice, that should represent the max powder you can get into the case, not necessarily the safest, just a wall to look for, when you do finally start loading.

Somebody will give you a "Quick Load" starting load. From there, using all of the safety protocols, work up your load. Of course all of this isn't necessary if someone has already done the ground work, for that particular bullet..

Well, you and I could do it, but I'm not going to recommend it to anyone else. Of course, we'd have to break all the rules to get it done and a 4' barrel might be necessary, but then who's counting? I think he might be in the 1800-2000fps area, when he's done..

Ah. Thanx. I was getting excited there for a moment.
