18.1 gr 2400 and a Win LP primer was my go to load for accuracy with the 188 hunter. The pistol primer seemed to help for me. Helped in the Mosin as well.
Does anyone else use pistol over rifle primers?
I really like 5744 for reduced loads in both 308 win and 54R Russian but it is very hard to get here. And when you can it is $40+/lb. I get more consistent velocity's out of it compared to 2400 also. Plus a little better case fill. Not much but a little. That load is up around 21 gr for both cartridges with 5744.

when I switch to pistol primers I need to up the charge to get back the accuracy I lose from the rifle primers.
usually that's a win/win because I get more powder in the case which helps settle many loads down even more.
speaking of Q.
I don't.
I do have a BBQ sauce recipe for wet cooking ribs and such in the oven.

TB, I wanted to try 5744 as well with my reduced loads in the 54r using the Accurate 215 gr. FP but I wasn't going to pay $40 for a lb. of powder. I have no ideas why that powder is so expensive, so I just switched over to H-4895 which can be reduced for both cast as well as jacketed for $26 a lb. locally and have been very happy with the results I'm getting.

I liked 5744, but at 40.00 a lb, don't like it compaired to powders
in the low to mid 20.00's. As to SP in larger rifle ctgs, am not really
hooked on them. I am hooked on SP's in the hornet & KHornet, as
I estimate a 10-15% improvement in accuracy with them over both
cast and jacketed. Prob a 5-10% accuracy in 222 over cast. Just my
opinion however.

762, 4895 needs dacron under 30grs. Especially if you shoot below 65*. That's when I would start to get click.......bang! Usually 28.5gr and under. But it usually shoots really good in that area so you need the dacron. Same way with 308 win and 4895. 28gr-29gr seems to be the node everyone runs into.

I never went that low with H-4895, I started out with 32.0 grs. H-4895 which is 80% load density in the 54r case if I were using 220 gr. J bullets data from the Hodgdon site with a 41.0 gr. Max charge. Hodgdon says you can start out at 60% load density with H-4895 and I got good results with the Lee 170 gr. RNFP powder coated using 33.0 grs. of H-4895 but the case necks got a bit sooty.
I'm up to 34.0 grs. with intentions of retesting that load for chrono data as well as to test out 35.0 an 36.0 gr. loads next weekend using the Accurate 215 gr. .314" FN which fits the long throat on my M91/30 very well. I had bought a lb. of IMR 4895 to try but decided I just didn't want to bother with a filler so I'm using it up in my SKS rifle with 160 and 185 gr. cast lead bullets for backyard plinking.

I've run H-4895 well below 28.5 grains, with and without Dacron, in the .308 as an experiment and never had any hangfires. Did the same thing with several other powders, too. I always used rifle primers. If you go below about 30 grains it's time to switch to Reloder 7, 4198, or 5744 anyway. I'm a huge fan of Reloder 7 for reduced rifle loads, and it's cheap.
So true Ian.
I view powders as having a velocity window where they work well.
If I want 1000-1200 fps I use Unique
If I want 1200-1600 fps I use 2400
RE7 is good for 1400-2000 fps
I wouldn't use 4895 until I was looking for well into the 2K plus window.

I prefer IMR-4895 to the H-type.
I can work it to the edge a bit further and it stays really stable in the small bores without a filler.
I use the same 22.5grs. in the 223,22-250, and 220 swift.
if I merely switch to the H type my groups go over the edge and just blow up.
I have also gone down to 24grs in the 7 mauser without any issues with both a 145 and a 168, it seems to mimic 28.5 with a filler in the 308.
I really, really like that load when the bullets have a nice soft nose for fox, and yotes out to about 125 yds.
I will say that 28.5 grs of 4895 and a case full of filler is one of the most stable and more accurate shooting loads ever with just about any decent 30 cal bullet you can chamber, in just about any 30 cal. rifle.
it surely isn't the only load out there and it is a pain in the butt to make but it will shoot.
we owe Frank Marshall a debt of thanks for that load.
but it's window is pretty narrow 28.5 to 30 grs is about it.
once you cross the 30gr area you might as well switch to 4064 it provides a better launch, and below the 28.5 a faster powder group is a better choice.

The really neat thing about Reloder 7 is when loaded up to about 1700 fps or more in medium, 30-cal rifle cases it burns so well that it doesn't need a filler and isn't very position-sensitive like 2400 can be. IMR 4198 is easy to light as well, but has a sharper initial burn spike. I find H-4198 a little more position-sensitive than the IMR variety until the pressures are higher.
