RE: 50-90 paper?
Well, Lordy be, I dumped 100 of the big 1.658 inch 780 grain bullets back into the pot, brought a tear to my eye it did.
That said, I'm sure that was a lot less painful than chasing a good load in the 50-90 at the bench, Kurt, mould set at 1.500 inch dead on, I looked at my notes while out in the shop, appears 105gr Swiss 1F will easily get the 1285 fps.
When weather permits, i'll cast up another hundred and see what they weigh at 16 to 1 and get some velocity numbers, will have plenty of working room at 105, slight compression, and not cramped for space to lay in a nice Black Magic grease cookie.

RE: 50-90 paper?
Well now Kurt, just following orders from The Grand Advisory Committee Spokesman, I thought 1.658 and 1300 fps was going to be too long and too fast, I double dog guaranteed I wouldn't be tempted to retrieve, turned on the pot and melted them while I put up 40 rounds of 500 Nitro 570 grain BBW #13 solid ammo in some new Jamison brass that came off the truck yesterday too.
I'm headed back out there in a bit, think i'll heat the pot and mould, cast a couple and see what they weigh and measure at 1.500 inch.

RE: 50-90 paper?
I'm in a vehicle traveling N/NE at a high rate of fuel consumption borrowing a Buddys laptop, hope this comes through.
Kurt, I have some numbers for you, I was out in the load shop at first light this morning, ran some across the chronograph, I had forgot and told you guys a fib the other night, I did indeed keep two of the 780 grain bullets, i had patched them and left em on the table when I dumped the rest in the pot.
I ran the big 780's first, went immediately to OE 2F.
110gr OE 2F went 1274 fps
115 gr OE 2F went 1297 fps
I used three of the 706's at 1.504" long.
110gr Swiss 1F went 1225 fps
120gr Swiss 1F went 1285  hit your rec on the nose with that one.
Loaded another at 120 grains, it went 1272.
Cant wait to get back home in a few days to cast and load some of each weight, even rinsing those five cases out at the hydrant in the cold and wind this morning was fun, this stuff gets in your blood.
BTW, rdncks Black Magic lube left a very nice wet lube star on the muzzle, I pushed two dry patches through the bore at conclusion, this is going to work, and Kurt, with your 1.500" bullet seated 250 thou in the case, the only pressure I felt at loading was the roughly the last 1/8th inch of a full chamber and breech close, I didn't have time to push a loaded round out with a wiping stick to see if I was wrecking the patches, but it sure didn't feel like it, will check that later.

RE: 50-90 paper?
Dang, just had a heck of a supper, and you bet Sir, accuracy, now, just what kind of accuracy should I be looking for when I get back?
I'll only be going out to 700 yards here, is there a specific group size at 100, 200, 300 yards etc you guys look for?
I have a Hoke tang sight that appears to go 370 minutes and a Distant Thunder front with post and bubble level, just how far will a 50 so loaded go with 370 minutes Kurt?
Thanks again, You're saving me a lot of work! ; ]

RE: 50-90 paper?
Nah, I'm making you a lot of work. Gunner do the ladder loads. Do a three shot find the best then do a 5 shot to see if it stands. Then go to the long range on a decent day, 15 MPH winds or less and see if you can keep 7 out of 10 in the white 16" dot on the iron at 700 to 1000 making good breaks.
I haven't used my .50 since the 09 quigley but I'm thinking about using it again because it is the most dependable rifle I have for long range. It has served me well over the years. I don't know how large that white dot is on the Alliance 1000 but during a fair day of practice I held 16 out of 25 shots in the white. The 600 at the Quigley 10 for 10 during the practice days.
I haven't done any work with the .50 using OE but I'm sure it will do just as well as the KIK or the Goex EXP did.
My Shiloh rough rider is the only rifle that looks like it had rough use with the bluing rubbed off and the front of the muzzle the blow back has removed the bluing back to the sight.
I kept track of the shots fired by numbering the primer bricks I only used in this rifle but lost track two primer shortages ago when the count was 19 bricks. It has shot over 25K shots fired with this rifle.
The .50-2.5 or 325 is not a rifle for every one. If you cant handle the recoil or the torque you will never get the most out of this caliber and the shooters will blame the caliber of rifle because of the poor accuracy.
I have more dust collectors I won using this rifle than any of my others.
The reason a dog has so many friends is because he wags his tail instead of his tongue.

RE: 50-90 paper?
LOL, then FUN work it shall be Sir, I'll write down your target recs when I get back home, right now I'm on a rooftop helipad in the blowing wind, Nice, you definitely put the time behind one, I have to say your 1.5 inch 706 grain bullet did load and recoil a lot easier than that 780gr missile at 1300 fps, what a rush!
One of the buds here ran a ballistic program on my bullet after he asked what I was up to with his laptop, he's a retired Mar-Soc shooter, I gave him a b.c. of .75 with my 780gr bullet at 1300 fps and .494 diameter, elevation of 4000ft, 35% humidity, we also plugged in a 10mph full value or wind at 90 degrees, here are the numbers he gave me when trying to see how far my 370 MOA rear sight will reach.
First, I remember I needed 65 moa to get to 100 yards, so we'll add that to the top number:
260.3 MOA to get to 1800 yards
Adding 65 moa
325.3 MOA to 1800 yards
12.7 MOA wind at 1800 yards
831 fps remaining velocity at 1800 yards, LOL
These numbers are only for fun while killing time, but it seems my sight will reach a mile and then some, and I have to say, a 780 grain bullet at only 831 fps should still be carrying some serious freight when it lands, if accuracy is found with this mould, this will turn into a lot of fun!
Thanks again Sir,
gunner
