For the fundraiser post that you're asking about when I used the Cooper 57M, it was 80 rounds shot at 50' as noted on the targets. The prone targets are tighter in ring size compared to the three positional shooting 50' targets. The winner that night in prone only dropped two Xs out of 80. It's...

Welcome from an easy 4 hours away, ask if you need help preparing for anything long range. ELR stuff has been in my world since 2012. We have been pushed to 4200 yards now but thats my life. Let me know if you need any help, cheers Osoh from central Wisconsin

Yes they are and a great time. Very nice rifle Rob I really like this rifle, what a great setup and extremely fun By now you may know already - DI Precision built Vudoo 360 RB-LP 25”x1.25” 13 twist Mullerworks with tuner in the Pro II chassis, been using a Accu-Tac bi-pod I had on another rifle...

So far Midas Plus has worked extremely well in the Cooper 57M and my custom 22L Here are a few pics from Friday night when the winds went calm to 3 mph from the 10:00 direction. Groups shot from my DI Precision built 22LR at 500 yards with Midas Plus while trying to true up Ballistic program. Osoh

It’s?? It’s just crazy **** but unreal. Just a simple build gone crazy and a few groups shot last Friday night when the winds went calm to a 3 mph from 10:00 direction while truing up a program - at 500 yards. Midas Plus ammo. 32.6 mils of vertical and 2.6 mils left for wind and spin drift...

Thanks

500 yards. 32.6 mils of vertical and 2.6 left for wind

A couple of groups, 3 shot target then adjusted program then the 5 shot groups to get correct vertical hold, 22LR is definitely different then center fire. We had calm winds of 3mph at 10:00

Ok, his JLK bullet orders

My close friend still makes the JLKs. Orders are back logged some since all the virus crap but folks are constantly asking for them. Osoh

So why is it Dreaded? Osoh

I had a slightly shortened 50 cal with a radius shoulder necked down to a 375 that held 25 grains more powder than a 416 Barrett. It was easy to push a 400 grain 3480 fps with H50 BMG. ** First barrel made it through load development only and was done. Then the second barrel made it - 10...

You should reach out to Tom Sarver at Thunder Valley in Kimbolton, Ohio and get some coaching on brass prep and reloading as well as load development and testing. So above you got some advice on powder charge and overall length, the jump to the lands compared to your chamber and throat may...

Lots of brass and stuff based off the 585, good times in the days of the wild catters. cheers osoh

I did ping targets with the Vortex 4000s out to 3500 yards in New Mexico at the NRA Whittington center ( white steel plates in the mountain side) and compared the results for error against my Vectronix PLRF15s and we were somewhat impressed on how close the vortex 4000s were against the...
