300 gr. 44 mag and my BBS carbine.....
Want to try some 300 gr. Hammer loads in my 44 Mag BBS Carbine but using the Missouri Bullets hammer head style they are
1.710 in COL and will not cycle or chamber thru the action being too long.
So came up with a plan to load them in a .44 Special case which gives me a 1.550 COL compared to 240 gr. 44 Mag which is 1.600.
The measurement from bullet base to crimp groove is the same as the MB 240 gr. bullet.
Made up a dummy round and it cycles and chambers fine. Just need to work on the load data which I found using Alliant 2400 powder.
1000 FPS out of the rifle would be a modest goal if pressure stays within reason.
Of course I had one spare MB 300 gr. Hammer bullet left to make the test round so will order up some.
Will be an interesting test!

Re: 300 gr. 44 mag and my BBS carbine.....
as long as the COL is right you shouldn't have any problems with the cycling as you stated. you might have problems with accuracy with the 300g., the ROT in the BBS 44mag. is 1-38. IMO, that's not a "fast" enough ROT for that weight bullet. 1-20 ROT would be better. as I mentioned prior this is just my opinion. keep us informed with your results. lastly, cycling issues might develope after multiple firings when things start to heat up and swell. Good Luck.

interesting .... can you seat the bullet deeper and crimp just over the edge of the top ridge (for lack of a better term)

Yes you can. However, you are reducing powder space, might want to start with low 44 spec. loads and work up.

Re: 300 gr. 44 mag and my BBS carbine.....
absolutely, that must be taken into consideration .... the manufactures of the bullets we use that provide crimp rings locate them so the loaded round will meet SAAMI specs .... hopefully the bullet manufacture provides tested load data

Don't run them too fast either. I ran some hard cast 260gr at 1300fps and they were going sideways through the paper. I suspect they were to fast and the low twist rate wasn't stabilising them.
Here a pic 50m two rifles, Henry BBS and Winchester Miruko same bullets. Interesting findings.

Say a 300 gr piece of lead traveling saying 1000 fps, and slap something sideways. WOW
I cast a 300+ gr 44, but I shoot 'em in the T-4's.

I am interested in your findings though.

Re: 300 gr. 44 mag and my BBS carbine.....
I'm going to try the .44 Special brass with normal crimp location. As a reference the 300 gr. bullets have same crimp location from bullet base
as my 240 gr. bullets with both being coated from MB.
Have load data showing Alliant 2400 powder with 210 and 255 gr. cast lead bullets in .44 Special and Magnum loads so I have a good
basis to figure a starting load. 10 gr. of 2400 should be within the higher end of .44 Special and at most just a tick below .44 Mag level.
In .44 Special in Lyman book a 210 gr. cast bullet is 13 -14.5 gr. with a max 14,000 CUP. .44 Special with 255 gr cast bullet is shown
10.5 gr. to 12.3 with max CUP at a low 12,700.
300 gr. cast bullet load in .44 Mag is shown as 14.0-15.7 with a max CUP of 37,200
I was thinking of a 10 gr. load of same 2400 powder given the .120 shorter Special case.
Have seen someone else loading 300 gr. cast in .44 Special with 9.0 gr. of 2400 for use in .44 special revolver with good results.
I have shot the MB 300 gr. bullet over 14.0 gr. of 2400 in .44 Mag case thru my Ruger SBH with 7.5 barrel and got 960-1000 FPS.
Will load a few and try in Ruger SBH and then in the Henry Carbine and see how they shoot from 50 yds.

Re: 300 gr. 44 mag and my BBS carbine.....
Hey forty four, today I was looking through the ammo safe and I stumbled across a box of of Cor Bon 320 gr 44's that my son n law gave me last year.
Had forgotten about them.
Wonder what bullet they use?
Gotta try them out in the BBB.
