does he know

On another forum some folks had talked with Hodgon and were told that SR4759 is made by General Dynamics in Canada who raised their prices out the roof because 4759 uses OLD OUTDATED technology in its manufacture. On this other forum folks are talking about using RL7 in its place with cast . Maybe Alliant could supply some data with Jacketed in some of the steel busting calibers. And its made in Va. ;)

A trait of 4759 is its bulkiness. That was / is desired in cartridges that were of the black powder era and as people began loading using the smokeless powders found they now had poor load density. 4759 helped alleviate this situation. So it is not just the burn rate that is being lost it is the ability to absorb volume. rp

RP is 100% correct about the load density. It's not just the burn rate.

Don't doubt that it is a great powder for the old cartridges but it also works great in my 6.5BR and 30DC. I hope I can stock up this coming year.

It works GREAT in my Smith .500's, too! In fact, it is the most accurate powder
I have tried in it. I shoot 23 grains of SR-4759, behind the RCBS 400 grain plain
base bullet, and I have shot clover-leaf groups at 50 yards with it. It is not a hard
kicking load, either. I havent chronographed them yet, but I'm estimating velocity
at around 1000-1100 fps. I think it will handle any wild game I try to hunt in Texas
at any rate.

Like was stated above, the bulk factor is what makes SR-4759 so attractive. There are
other propellants that can be used for reduced loads, but all of em, except for Trail Boss
are not bulky enough to fill the case correctly and then you can get into some dangerous
areas, like if the whole charge ignites at the same time, and I dont wanta get into putting
fillers, like cream of wheat into the case, either.

AA5744 works like SR4759 and is not position sensitive. That is my go to powder in my 260 Remington Striker. Just another powder to stock up (hoard).

I emailed Dave Campbell at Hodgdon too and confirmed that it will no longer be made. Then I read "somewhere" that there would be one more run of it. Of course finding ANY powder these days is tough, never mind favorites!

And SR-4759 certainly was a favorite of mine...
