4227 rocks in supermag revolver rounds
(IMR)4227 is the only powder I now use in the .445 Supermag.
It's a great powder for all the supermags where the pressure can run up into the break-action/lever-rifle range and above (45kpsi).
No you won't get all the velocity of 110/296 but you do get amazing accuracy and a much friendlier pressure curve.
For several reasons I have given up on ball powders in general.
Safety and accuracy are more important to me than that last (potential) 100 fps.
I always wanted to try Herco in the 44 Special but have been getting nice results with the usual suspects: Universal and Unique.
Universal meters way better than Unique so it usually gets the nod.
Consequently the very few times I have seen Herco on the shelf I passed it by, having a fair stock of powder already.
Having also developed loads using some more obscure propellants like N105 and CSB1 for the Special,
Herco fell even further behind on my interest and time scale.
N105 may be the most efficient powder for the 44 Special.
It will deliver the highest velocities at 15-20 kpsi of any powder I have tried or modeled using QuickLoad.
It falls between Herco/Blue Dot and 2400 in burn rate and burns pretty clean even at the low special pressures.
Too bad Vihtavouri has almost priced themselves out of the American market.
Their powders are famous for burning clean.
I got several pounds of N105 during warehouse scrounge and clearing sales during the last big powder shortage.
There were a lot of small batches of odd-ball powders that appeared when the regulars went away.
