Yes I find CSR particularly gruelling with my dodgy knees and knackered back! Takes all the fun out of it for me so I don't do it. I'm sure an AR would be great to shoot at the MQC. Strictly no fmj though. :-)
The run down timings have been extended from 30 secs to 45 secs for 100 yards, it's nearly a walk lol, mind you there were a few on Sunday! GGG brass is pretty good to reload but you have to swage the primer pockets, not such a chore if the brass is free. Quite a few competitors (myself included) use milsurp/factory fodder at 100 and 200 yards then use the brass for reloads. Glad you enjoyed it Dave, weather certainly helped.
For the short ranges of CSR, I think GGG is fine. Works great in my .223 out to 500, but then for some reason won't even stay on a standard target at 600. My .223 is shot out though so I suspect the rough barrel is causing it to go unstable early. Just waiting to get it re-barrelled once I've finished the .50 AB.
Contemplating doing the next CSR though. It still groups 2 moa with GGG out to 500 which is good enough to have a bit of fun at the CSR comps.
AR would be fine at the MQC. Considering building one for CSR and MQC. Looking for cheap parts, again though it may have to wait until after the .50 AB.
True ....but the unbridled joy of the 100 to 200 yard 'assault' stage where you have carte blanche to fire as many rounds as you can in a minute (multiplied by all the shooters in the detail) certainly creates an interesting soundtrack!
Ooooh bring tears to my eyes thinking about all that erosion on my match barrels ;-P I think you have to make a full commitment by buying a dedicated big mag black rifle to find it anything more than a day of frustration. Though I do appreciate your enthusiasm lol Id be happy to do it again but with a borrowed AR rifle.......
