4.3 dipper/SR-4759

[Predator II]

:)Shot my camo Ml-II today to get the scope zeroed at 50 yards. Used 4.3 dipper of 4759 and the 250 shock wave. I double saboted with a 28 ga. cup and 1 wool wad and used a Hornady sabot and CCI 209M primer. I had to allow 10 minutes cooling time. Without weighing charges or wiping between shots, the rifle was sighted 1 inch high at 50 yards. The group was one inch which is remarkable considering I was adjusting the scope after each shot. This load was very responsive and the new barrel seems to want to shoot. I will find out more when I move to 100 yards. This charge approx. 48 grains has performed outstandingly in 3 different Savage Mls. Maybe we are on to something here.

8-)Yes you are on to something but it is something that has been known for a while. One 4759 is a fine powder for the 10-ML it will shoot very good groups with power.

However the drawback is the sub-base. Now many shooters don't mind the sub-base and I don't really totally discourage them. But all of the faster burning powders like 4759, N110, and Lil Gun with shoot rather quickly with a good sub-base.

Now don't take this wrong I'm only expressing a personal opinion. If the load works for you do what works. Still I'd comment this is a rather ineloquent solution. Raising pressure to soaring heights is one way but burning a bit more fuel will likely provide the same speed and be more likely to provide consistent results for a larger portion of shooters. It does not require a sub-base and is also much easier on vent liners. Vent liner replacement occurs twice to three times as often in high pressure loads.

OR perhaps not at all with an improved vent liner position, BUT that is yet to be proven.

I used a Lee dipper with 4759 and then weighed it on a powder scale and there was 3 grains difference than the chart. So I weighed a 140 grain bullet and it weighed correct. This is an older RCBS 5-0-5 scale. Before I retired I took a dime to work and weighed it there and took it home and weighed the same dime and it was right on. I was thinking about doing the same as it has been about 10 years since I used this scale. Point is ,The dipper off or the scale?

The Dippers are as consistant as you are, NOT a specific weight, but what you dip should be VERY close to the next time you dip.

Your scale will be very accurate as long as it "zeros" when empty!

I suggest that you dip and weigh ten loads, to see how accurate you are, then recheck your ability fairly often. The Lee Dipper Chart is ONLY approximate, and some powders scoop better than others.
