SR-4759 in .22 CF's

Has anybody here gained any practical knowledge concerning 4759 in larger capacity .22 CF cartridges such as .219 Wasp, .225 Winchester, etc.? Specifically, I'm thinking of trying it in a .22 Savage HiPower with 60 gr. cast bullets. I've used Unique, 4227, 2400 but never 4759- my all time favorite for .30 cal. midrange loads. Just wondering if I'm wasting my time. I can see myself coaxing those big granules through the funnel and down that tiny neck.

I have never loaded for a 22CF, but I have used a lot of it in the 30-30 and 30-06. I had to drill out the drop tube in my Redding powder measure because the powder was bridging. A friend used Varget and, I think, Benchmark in his 223. Reloader #7, H4227 and 2400 should all flow freely through the neck of a 22.

  I've used 4759 in 7mmTCU which is a 223 case expanded to 284(open wide, say ah!).  The Redding #3 I use doesn't bridge if I tap the powder measure stand with a teaspoon(one I use for mica).  I have a funnel from Midway USA called  Frankford Arsenal. It has interchangable spouts for the case size.

  When I take the powder off the scale and pour it into the funnel, I pick up the funnel, case and all, and pop it down on the bench. Just using a light rap to make the powder fall into the case does it.  That's about how I've handled it, a little like using the old Lyman #55 with the knocker on the front to make sure the powder falls. Can be done!

I'll look in some of my old Lyman manuals: I'm sure the data is in there somewhere. There may also be SR80 data floating around and you can use that as a basis for SR4759 loads. I found that a .17 caliber funnel works well with the .22 Hornet.

I found 1 (one) load using SR4759 with a 60-gr. GC bullet in the .22 Hi-Power: 13.0 grs - Lyman 228367 - 2000 fps. This was in Lyman 41. In Lyman 43, the velocity for the same load and bullet was dropped to 1906 fps and “228391 Plain base. Use lower vel.” was added. Sharpe has a 60-gr. GC (0.375” seating depth) - 13.0 - SR80 - 2050 fps. Belding & Mull (1937) has their 60-gr. B&M 22960 - 13.0 - SR80 - 2100 fps. I guess not much load development was done due to the odd bore size. Today I checked some of Sharpe's SR80 loads for J-word bullets in the .22 Hornet and the results were not what I expected. With 45- and 30-gr bullets, substituting SR4759 gave velocities 400 fps or more lower than the SR80 velocities listed. I did not run into this situation when I did the same thing with the 7.62x54mmR SR80 data; if anything the velocity was higher with equal weights of SR4759. SR80 must have had some weird burning characteristics. I also checked Lyman's 55-gr. J-word - 7.0 - SR4759 load and got about 1530 fps versus their 1400 fps.

As far as getting the powder in the case goes, I just pour it against the side of the funnel and the grains sort themselves out on the way down.

Thanks. I never thought to consult my Sharpe's handloading book to extrapolate from SR-80 data.

About 20 years ago I was working up loads for a .22 Hornet Model 340 Savage.  At the time I didn't cast for the Hornet.  One load I tried out was 8 grains of SR-4759 with a 45 grain Speer soft point.  It turned out to be the most accurate Hornet load I ever shot in that rifle.

Thanks BerdanIII. Good info. Downloaded same into my HiPower file.

I use it in 223 with 55 g as cast no gas check Alox lube. Shoots pretty good with no leading. Some unburned granuals left over. Run a dry patch through once in a while. Works as good as anything I have tried so far with the possible exception of Trail Boss. Problem with Trail Boss is that it is absurdly expensive in Canada.

I tried it many years ago in 22 Hornet but gave up trying to get those large powder granules into those tiny necks.
