44 Rem Mag Reloading Powder?

I am about to compete in silhouette shooting using my Marlin 44 Remington Magnum. I am going to use Sierra Tournament Master 220gr FPJ bullets. I need to know what type of powder, brand and model and also the amount to use per case. I want accuracy!!!!!! 44 Rem Mag Reloading Powder?
Ryan, try H110 from Hodgens. Its burns clean and is the most accurate powder I use for the 44mag and 480 ruger loads. I have the ruger 44 semiauto carbine rifle and the ruger 44 lever rifle, the loads I have for my pistol work very well in both of these. The 220 gr FPJ with a winchester magnum pistol primer and 22.6 gr of H110 will make a good starting load for you. 44 Rem Mag Reloading Powder?
Unfortunately no one here can tell you which powder and how much will be best in your gun. As that what is accurate in one gun may be unacceptable from another. H110, 296, IMR-4227, and 2400 would all be good powders to experiment with. To find out which is best, you will need to experiment with charges and over-all lengths. Considering how many different combinations you could make from just those 4 powders and various over-all lengths, you could end up making nearly a thousand rounds just for testing purposes. If you want excellent accuracy, be prepared to have to step charges up by .1 grain incriments. Besides that, there's no guarentee that one of those four powders can deliver what you are looking for.


When you say you are about to compete, it sounds like you waited too long to develop a good loading. It takes months to years to develop nice pet loads.
first you need to buy the Sierra loading manual (they may offer information on line)


then you need the reloading equipment - Lee can get you started for the least money


I used to use 2400 for lead bullets and 296 for jacketed but there may be some better new stuff out there


then you get to pick your powder, primer, and case since you've already picked your bullet


then you get to try different amounts of powder to see what gives best accuracy and maybe vary your crimp (how tight - assume you will be criming in cannelure)


then you get to start all over again with another powder - or primer


if you are interested in accuracy


you aren't going to get it done in a weekend


or you can get the loading data, forget the rules, load about 2% lighter than maximum for the Marlin and hope it hits on the target and doesn't blow up in your face


if you get in a hurry reloading, it can get you maimed or killed

my criteria for 44 mag is for lighter loads (cast ) I use blue dot becasue it burns so clean. For jacketed bullets of 220 to 240 g I use Hodgdon H-110 and for all bullets heavier ie 300 g plus I switch to WW296. I do not shoot a 44 rifle, but I have always gotten the best accuracy and velocities from H-110 with the lighter jackets, out of my Rugers. I will not suggest a charge weight due to the difference between rifles and handguns. MY reliance has always been on a Hornady reloading manual
H110, 296 and 2400 are all good choices. I even worked up a good load with Blue Dot once. But your accuracy is probably going to be affected more by other factors. Make sure your brass is all the same length and crimp consistently, and your 44 will shoot a lot tighter groups.
