    I got hold of some RL-33 and thought I would see what it would do with some heavier bullets. I started with some 230 Berger OTM's and loaded them with R 9 1/2 primers to a coal of 3.640, which was just off the lands. I hooked up the Mag speed and went to work. I only fired one round of each load, but velocities went up fairly consistently:

    85 grains ...... 3024'......mild
    86 grains....... 3075'......
    87 grains....... 3113'......
    88 grains....... 3138'...... primers starting to flatten
    89 grains....... 3174'...... slight extractor mark with a little stiffer bolt lift*
    *I have found that ANY stiffening of the bolt lift with the BAT action is more than the cases will take for long!
    I wasn't shooting for group, but all five of the shots went into an inch.

    I was running out of time but wanted to see if the 215 hybrids would like a case full. I loaded 90 grains which filled the case to the base of the neck. Obviously, the load was compressed, but not too badly, as was the case for the 89 grain load in the 230's.

    90 grains........3213'......not max load. I could probably compress 91 grains and get another 40+ feet of velocity.

    I hope to get some time later to work up some velocity loads. I was really encouraged with the velocity as a max load of H1000 probably is not over 3100' with the 215's. If it works out accuracy wise, I may be able to load with the same or more velocity with a lot less pressure than the H1000.
    As a side note, I heard from our local sporting goods shop that Alliant has taken a government contract and the Reloader shelf powders are going to be hard to come by! ........Rich

    Rich, that looks like a real nice performance level from that 230!!

    Ya, I think around 3100', that would be pretty potent!

    Rich, very nice velocities. I shot the 30/375 S.I. at 1513 yards on Saturday with the 215 berger and 85 grains of RL33. Drops gave me a velocity of 3035 fps, it shot about .75-1 MOA with most of the dispersion was windage, as the wind was tricky. BTW, i got my die from Whidden on Friday.

    Way to go Riley; that is pretty good shooting! Glad you got your die back. I assume it is better? Were you able to get the other ones sent off to Marlin?

    Ya, I was petty impressed with the velocities. Of course a 28" melonited Krieger doesn't hurt:D.......Rich

    I didnt get Marlin's sent out yet, i will get them out tomorrow. Everyone that was watching were dumbfounded it was possible to shoot that far with that kind of accuracy. There was definitely an advantage with the 30/375 S.I. over my 284 win at that range. I bet RL-33 will shoot really well too. I am going to fireform my other 50 cases this week and sort them. It is a lot easier to size, but it looks like the bases of the cases are being sized down too .532, which IIRC, is the same diameter of the chamber.

    So the old guys thought that young whipper snapper had a little lube on his primer until they saw the results huh:D

    I did the shooting up at our cabin, i shot all the way across the bay. They thought i was shooting at the Island which is about 500 yards away. Lol. One of the guys that was watching we hunt with every once in a while and he asked if it could take down an elk at that range, we said no, but a deer isnt completely out of the question. :cool:

    I edited my last post after you commented incase you missed it.

    Just for the record, it WILL take down an elk at that range:D

    I meant with the load we were using probably not, but with the 230 at 3100 and 7000' ASL it will! Doublezranch will be coming to our cabin this summer and he and I will face off on a 6"x12" gong at 1513 yards. He will have his 300 rum stoked with 103 grains of RL33 and a 230 target at 3200 fps.

    This aint the first time I have heard that those BATs handle pressure very well, er, mask pressure if you will.

    Have you found a accurate load with 230 Berger and REL 33? Was the node close to 3100 fps?

    I have been so darn busy the last year that I haven't had time to work with it anymore. As far as I got was some pretty impressive velocity.........Rich
