Boring thread about SR-4759

[shoot2reload]

There have been plenty of discussions about metal-can IMR SR-4759 vs. plastic-can, and from what I gather the older metal-can powder seems to be a touch more potent.

So is there one (metal vs. plastic) that tends to be more accurate?

The reason I ask is, with several sabot/bullet combinations I've never been able to equal the accuracy of AA5744 with my particular lot of older metal-can 4759.

Would it be worth it to buy (and try) some plastic (new lot) 4759, or should I just be content with vanilla 5744?

I don't think you can really know until you try it. There gets to be so many variables with MLs that it is hard to predict what the gun will like and at what amount. Lot of people move on from 5744 in search of more speed and there for flatter shooting. I found that SR4759 to be cleaner burning than 5744 and to be very accurate. All I have ever had was the plastic bottle.

For me the accuracy was about the same. It just takes about 3 more grains of powder from the plastic containers to get equal velocity. 4759 has been as accurate as any of them I just have to tweak the charge amounts to find the best groups. Your rifle may just like 5744 better than anything else.

I owned several that loved Vanilla and the 300 grn XTP! Deer killing machine!

Tar is right about the 5744 and 300 gr XTP's. Every rifle I tested this load in shoot well with it. It is a great general purpose load, easy to ignite, plenty of power, accurate to 200, cheap, and can be loaded with scoops instead of weighing.

I started out with the book loads of 4759 (plastic jug) in my 10MLIISS 50 and have never tried any other powder. During my first range sessions with this gun years ago I found it shot the best groups with 43 grains.

According to the published load info, 43 grains of 4759 powder should produce a velocity of 2330 fps but my actual bullet trajectory indicates a much slower velocity. My bullet trajectory indicates a muzzle velocity of only about 1900 fps.

I did read somewhere on this forum the published load data for 4759 was based on the old metal can 4759 powder and not the new plastic jug powder. I was hoping that the company would eventually update the load data with the new plastic jug 4759 powder as it is the currently produced powder.

4759 powder has worked well for me. I have never had an ignition problem, it is reasonably accurate @ 100-200 yards, seems to burn fairly clean, and with a 250 grain Shockwave bullet has hammered some nice whitetail bucks if I do my part.

I am guessing there may be another single powder that is as good or better than the 4759 I am currently using but I have not gone to the expense and trouble of buying/trying numerous other powders/loads trying to find something better.

Heck yeah Dave, if it ain't broke etc. I bought an 8 lb keg of 4759 plastic after shooting up 6 or 8 metal cans and simply had to use a few grains more. It is an excellent powder.

[tim1jr]

I have only ever shot 4759 out of the plastic jug. 42 grains. My guns loves it so I have never tried any other powder. Never had ignition problems an I have shot sst's, xtp's, and Hornady 4500 which is there .458 bullet. Have shot all with good accuracy.

[mountainam]

It's a good stabile powder that performs well with small amounts. I use it in my .222 for a .22mag duplication load. Although it more than duplicates a .22 Mag at 2550 fps, but they cost me 1/3 the price of a .22Mag. Just think, if you're lucky enough for it to perform well for you in your SML rifle, you are getting 4 shots for the price of 1 compared to the Black Horners. Whether you use as a single or a primer for your duplex, it's here to stay.

Anyone have some recent "plastic jug" 4759 powder load data, chronographed velocities, etc. for a 10MLII 50 cal with the usual 250 and 300 grain bullets?

Thanks, Dave

I would really like to see some of that data too. Its highly recommended in the NULA for its accuracy and i can get it locally at several locations. A comparison to N110 would be extremely helpful too. Ive seen a couple traces but im not sure which version was used.

SR4759 is the only powder I use and have for several years now. In my 50 ML I 46.0 grains of old lot will shoot a 250 Barnes Expander @ 2350+ fps and its devasating on deer. I bought a 5 lbs metal can back a few years ago before Hodgdon bought IMR out so I have enough to last me for several years. Mike

Nothing boring about this thread at all. My .50 loved 41 gr 4759 (plastic jug) and the 250 xtp. No doubt I could have found other loads with it as well. I enjoy these threads about the book powders and xtps! I don't think I ever put 300 gr xtps on paper with 5744 other than to sight it in but I killed a pile of woodchucks with it. Those days were a lot of fun.

[Dave W]

42gr -2000fps with 300gr bullets, 2100-2200 with 250's, same load. In the .50, N110 was 1-200fps faster than 4759 when both were used as duplex booster at the same charge weights. This data is a couple years old.

[fishdog52]

Count me as another guy that has been dazzled with the performance of 43 gr of 4759 under a 300 gr XTP. Accurate and devastating.

[Richard]

I have started using it as my booster in duplex loads replacing N-110. It is cheaper and easy to find. My only complaint is that it does not throw as well (as N-110) from my powder measure . 5744 is another that does not throw well despite being a good powder.
