I have a 45 Colt Redhawk, I also have a dilemma. I have looked high and low for Redhawk level loads for a 325 gr. cast bullet. I finally extrapolated a max. load of about 21.5 gr. of H110. Does anyone have any loads they'd be willing to share?? I realize I probably should have bought the 300 gr bullets instead, but  hindsight is always 20/20.-----------------------------Bob

 I like 23 gr. of H-110 under a 300-325 gr. LBT lit by a CCI-350 primer.......This is safe in my 5.5" Redhawk..

I have shot 25.0gr of H-110 with a Cast Performance 335gr WFN out of my 5.5" .45 Redhawk for just over 1300 fps and groups around 1 1/2" at 25 yds. Hope this helps.

God Bless

Pourboy - FWIW:

Hodgdon's #26 manual lists a 325 JSP H-110 load starting at 21.0 gr/1149vel/24,400CUPp and a max load of 22.0 gr/1260vel/29,800CUP.  The Win296 load shows a 325 gr. slug (assuming cast, not identified in the manual) starting at      20.5 gr/1119fps/24,000CUP      and a max of      21.5 gr/1219fps/29,200CUP.      This data seems a bit backwards to me - if H-110 and WW296 are the same powder, I don't understand how the WW296 load can be slower shooting an assumed cast bullet (jacketed loads are identified) with the same components shot from the same test barrel.

John Taffin has posted this particular heavy load in the majority of his articles:   NEI KT 325 gr/21.2g H-110/1139 fps

Alan,

Those differences in the loading data with H110 vs. W296 are nothing more than the differences we see from lot-to-lot of powders. (hence the need for reworking loads when dealing with a different lot of powders)  The differences just between lots of powder can make the differences you see in loading data!   Yes, be assured though that they are the EXACT same powders coming from the same factory at the same time!

God Bless,

Thanks for the info Marshall and for being patient with my newbieness!

If the bullet used between the two powders was the same(both cast or both jacketed), I can easily see how the lot-to-lot differences would account for the minor velocity differences.  But in the #26 manual data, the pressures and velocities are based on cast vs. jacketed.  Most data that I've looked over shows a direct correlation of  increased speed when working with cast vs. jackedt bullets.   John Taffin's  45 colt data from AH magazine (5.5" Redhawk 45 colt) bears this out:

BRP 300 gr GC/21.5g WW296/1208 fps
Hornady 300 gr XTP/21.2 g H-110/958 fps

This data makes sense to me.  The XTP (all jacketed bullets) should be slower than the cast (all quality cast) BRP.

What can I say...I like this ballistic stuff  :biggrin:
