Anyone reload for the 4506

[shooters edge]

I am looking to find the right OAL for 200 gr swc for a 4506 .45 acp.

I load for a 645, the model before yours. Bullet is a Lyman 200 gr lswc BB i cast.

The bullet length changes with the alloy used.

So i measure to the bullets shoulder.

I no longer have a 4506, but, as I recall, it wasn't picky about OAL. With a 200 gr. H&G #68 or copy, OAL should be around 1.24", give or take just a little. You may or may not have to fine tune the OAL for flawless feeding, but it will still be in the vicinity of 1.24".

Best loads will be with Bullseye powder starting at 3.5 grs., though that may not be adequate to work the action in some guns. Somewhere under 4 grs. will be your most accurate load. Other powders may work as well, but it's unlikely you'll find one better than Bullseye.

Use a .452" bullet; alloy is not real critical, but I've seen best results with a bullet in the 12-15 BHN range, close to wheelweight alloy or just a little harder. Good luck-

I load for my 4566. 1.250 COAL. 4.8 grains of HP238 with a 230 grain round nose bullet.

Use whatever max. COAL" works as long as...

your loaded cartridge passes the plunk test in your pistol, doesn't exceed SAAMI COAL" (1.275") & feeds properly from your magazine.

I too load the Lyman SWC. I never knew what the numerical value was. I just knew that just a tiny bit of the bearing surface showed above the case mouth. I’d put 8 loaded rounds in the magazine, If they all went in easy, and came out easy, it was all good.

My 645 and 4506 shoot the Lyman 451630 (l think) that I cast, really well.
200 XTPs with a big dose of Accurate #7 is another good one.
The Nosler 185, especially in the 645 is the Beat em All Best.

It’s been my experience that 645s and 4506s are finicky but give them what they like, and they’ll shoot 2 inches or better at 25 yards.

I only reload .45 Super for the 4506, but I load it to 1.23" COAL, and use 230 grain flat point jacketed.

SO DO I. BUT A BIT SHORTER AT .925. JP

Of course how much "exposed" bullet bearing surface of those 200gr SWC'ers is above the case mouth will be dictated by how much leade/freebore your barrel has & if it passes the plunk test.

My 1980's Colt 1911 Mk. IV had zero leade/freebore & the seated bullet's COAL" had to be closely watched, especially with new bullets.

Almost all of my 3rd Gens have shown to have adequate leade/freebore for all but the most extreme situations.

My CS9 & CS40 both had zero leade/freebore though, like my aforementioned 1911, & they all have now been relieved of that restriction after purchasing the appropriate throater reamers for them from Manson Reamers.

It's nice not to have to load short. Now they can stretch their little bullet legs.

PS: I have my 4586 setup for 45 Super loads. It's my 45 Auto SledgeHammer.

4506 is nice.

It was my Duty Pistol when I was a LEO. But I always loaded 230 grain LRN or FMJ bullets to simulate our duty ammunition, Winchester Ranger 230 grain JHP.

I cast and shoot 200gr bullets sometimes. My all round load for my 4606/625 mtn gun/625's/1911's is my cast 230 gr. truncated cone bullet pushed by 5.5 grs. of WW#231. I standardized on this many years ago.

The 4506 by and large isn't finicky about overall length at all. Seat the 200gr SWC so that a thumbnail thickness of the bullet shoulder is sticking out above the brass case.
