<font color="purple"> Does anyone have any experience with the EFR or LRT on a big caliber with a break?
[/ QUOTE ] I put a lot of shells thru my 50 with a Loopie VX-III 4.5-14x50mm with 70 MOA using Burris sig before going with NF and Burris Xtreme rings. (updated to 40, 60 and 90 MOA rails) The Loopie is now on my custom 375 Kirby/Lilja/RUM with a holland QD brake, trigger job, bedding. Pleasanter shooting tac driver. (Pre CANTing with a 35 deg rail)
This reverse thrust hysteria is all wives tails (probably, but look at the time/pressure charts and knowing the Sin(30) = 50%, the mathematics says it's all BS unless the optics are built like car seats (only protect you from forward acceleration). Not true in NF with etched in glass reticules. Ez to test, just mount a scope backwards and fire a few rounds.
Use a Serbu carbine- half the weight and 1/4 the accuracy of my State Arms Super shorty - Serbo are the most famous, most inaccurate 50 you can buy (of the single shots (thanks to the google god )). If you want the ultimate kicking gun, well made, sloppy shooter (you don't plan on winning on the bench) this is a great gun to experiment with.
