www.montanabulletworks.com/product/44-mag-444-marlin-360gr-wln-gc/Montana Bullet Works offers a double crimp groove 360gr wide long nose gas checked bullet for the 44mag and 44 Marlin. The top groove leaves a .435” nose to crimp length, which allows for use in a Super Black Hawk. I am looking for full on 44mag loads with H110/W296, 300 MP, AAC #9, any/or mild to midrange loads using faster powders like W231 etc. Thanks Matt

You might be able to extrapolate from 45 colt 360gr. data also

H-110/296= load to the base of the bullet without compressing the powder.
4227= load to 103% of the usable case volume after bullet seating. This involves some measurements and math but works great if you do it.
#9 usually maxes around 80% of usable case volume after bullet is seated. Again measuring and math.
300mp= 94-100% usable volume.
These are generalities, but have worked for me in calculating max loads in strong guns.

Thank you. They don’t have data for that 360, but they have data for the Bear Tooth 355. I’ll look on the way back machine for info on that bullet. |

Thank you. They don’t have data for that 360, but they have data for the Bear Tooth 355. I’ll look on the way back machine for info on that bullet. It turns out that the Beartooth 355gr appears to be almost identical to the Montana bullet works version. Nose to crimp length for the top groove is a little different, as the BT version is .450” and the MBW version .435”. Hodgdon has lots of data for the BT bullet that I can extrapolate from. Thanks |

I have used these.
My loads were developed for a 7.5" Redhawk using H110 at a COAL of 1.780(lower crimp). The chronograph said an average of 1446fps. Not much fun to hold onto, would be better at around 1000fps.
Wish there were more long bullet offerings commercially like this.

Hodgdon has a W231/HP38 load for that big girl at 1000fps. Should be a lot of fun to play with that bullet. |

Be careful with that above linked data, I noticed all of the stated powder charges, (using Enforcer powder)and velocities were the same between the listed 325 and 355 grain bullets, I can’t believe in that much coincidence? Steve

Steve I agree completely! That last load with Enforcer is way off I would guess. Also some others in there that I would be suspicious of. Enforcer is 10-13% faster than 110/296 so loads should show that difference. |

The H110/296 and W231/Hp38 Data was taken straight from Hodgdon, so I’m confident in it. However, the MBW bullet is slightly different than the Beartooth bullet, so I’ll have to account for that. I noticed that the MBW bullet is identical to one offered by Accuratemolds. |

Measured (Midway digital clipers) some BTB 355gr WLNGCs that I've had for a while. The nose to crimp: BTB 355gr WLNGC (actual measurements): Top crimp grove: .431" Lower cr. grove: .505" Montana Bullet Works 360gr WLN-GC (Website): Top crimp grove: .435" Lower cr. grove: .500" For all practical purposes, these bullets appear identical. BTB (My photo)  MBW (MBW Website)  Hodgdon online data has load data for the Beartooth Bullets (BTB) version hodgdonreloading.com/rldc/ Paul |
