.44 Remington Magnum
I'm looking for loading data for loading a Lyman 310 grain flat nose cast lead gas checked bullet in the 44 Mag. This will be a hunting load. Thanks.

21.5gr. of H-110. Back off 10% or more as you don't say what gun you use. This load is what I use in my Ruger Redhawk and Dan Wesson. 0 -
Most manuals I've seen say to not back off more then 10% on H110 loads. 0 -
Absolutely do NOT back off of H110 or W296 (same powder) loads. Reduced loads can result in hangfires, failure to fire - or the opposite, VERY high pressures. Neither powder is suitable for experimentation. If you can find a tested book load for your exact components, use it EXACTLY as is. If not, it would be far better to choose another powder.
My current (#49) Lyman manual shows a 300-gr GC cast bullet (mould #429650). Cast of an alloy other than pure linotype, it would run a bit heavier, so that's likely the bullet in question. They show 12 different powders. Their loads for H110 are 17.7 to 18.5 grains for right at 1000 fps. Magnum primers are called for.
The same speed can be achieved with 2400 (15.7 gr), W296 (19.0 gr), or either type of 4227 (19.0 gr). They recommend a magnum primer for the W296 and H4227, but standard primers for the others. All the pressures run about 37,000 CUP except for IMR4227 which ran 33,000 CUP. (Using a standard primer with IMR 4227 may be the reason for the lower pressure.)0 -
Would it be OK to use standard large pistol primers? 0 -
With H110? No. H110/W296 requires a very hot primer, a full charge of powder, a heavy bullet and a firm crimp.
It is a "throttle to the floor" powder but has very specific needs. Those four things are among them.
I personally don't like to use H110/W296 in handgun loads, for those very reasons. I'd much rather use AA#9, 2400 or 4227 for heavy loads.0 -
I haven't made up my mind about what powder I'll use. That's why I was asking for advice.
All I have is standard large pistol primers. I use them in my 45 Auto loads. I'm sure they'll fire off a 44 Mag load. [?]0 -
Scott,
Read what everyone just posted, if the load calls for magnum primers, use them. Your statement of "it'll light them anyway" is not correct, slipshod methods, and substittions will get you in deep trouble.

Bottom line - A standard large pistol primer will make a 44 Mag round go BANG. Yes, or No?0 -
That is correct. It IS "yes or no."
It might, but then again, it might not. In the "might not" column, we have failure to fire, hangfire and what I call spontaneous omnidirectional disassembly.
All of those happen at random. You have no choice.
Care to gamble?0 -
I just learned that Winchester large pistol primers say right on the box, "For standard and magnum pistol loads." How does that work? 0 -

I used to load 7mm Rem Mag. I never used a mag primer. Never had any problems.0 -
First, this thread was specifically about 44 Magnum revolver loads, not the 7mm RemMag. Second, the magnum primer issue is specific to one of the recommended powders, H110/W296. In handgun rounds, with that powder, a magnum primer is required. Standard primers can lead to trouble in THAT cartridge/powder combination. I hope that's clear now.
Winchester primers are formulated SPECIFICALLY to work with Winchester powders. They are (in general) hotter than comparable similar primers. So when they say that their primer is suitable for standard or magnum pistol loads, it means just that. They are a good choice for use with H110/W296.0 -
I have a wincester load manuel. For that round it recommends a wincester or magnum primer and a VERY heavy crimp. So the way I read it wincester primers would be ok for a powder like 296 or 110. Failure to follow this procedure could result in poor ignition and /or a squip load to quote wincester. 0 -
I've decided that I'm going to use #2400 powder. It produces the highest velocities with the bullet that will be used. Thanks for all your input.
Looks like you got your feathers ruffled for nothing, Rocky Raab. [?]0 -
I was more frustrated than ruffled. You at first asked a reasonable question and then practically argued with the replies. Now it seems as though you've answered your own initial post by looking it up - which you might have done all along.
If my assistance is unwelcome, that's fine. I'll simply not reply in the future.0 -

Oh settle down bud. I did pick up a couple of boxes of CCI #350 Large Magnum pistol primers. I also have Winchester Large Pistol primers. I use the Winchester primers in my 45 Auto loads. Thank you for your concern.0 -
Make sure your cast bullets have gaschecks! I learned this the hard way with my Md 29. 0 -

I rarely shoot gas checked bullets. However, this particular mold casts a gas check bullet.0
