<font color="purple"> The pedestals are good, but don't hold the rifle against recoil and with a super long barrel (34" plus) this is a problem because the bullet hasn't left the barrel before the rifle recoils back. This results in vertical stringing often called "magnum shot". This effect was witnessed with the MOAG and it was actually quite severe. At 2k, one out of every 6 or 7 shots would go 2-3 minutes high for no other reason. So I would recommend a one piece rest with a recoil strap around the butt of the rifle or a muzzle brake or both. </font>

Just a quick clarification. Muzzle brakes (MB) only affect the gun after the bullet has exited the barrel. MB work by re-vectoring the jet propulsion either neutral ( 90 deg ) or up to about 30 deg reward (subtracting 1/2 their thrust from the rear impulse). That's one reason MB don't help the optics system, they actual make things worse.
Good point about <font color="brown"> vertical stringing often called "magnum shot". </font> - awesome story - writeup and info. Congratulations again to you and your entire support system.
Your one piece rest is really cool looking. It looks like my Caldwell <font color="brown"> ROCK BR </font> will fit onto my Caldwell Lead Sled so I can get something similar (not as nice tho).
I think I want a 7mm Allen Uber Mag with a 48" pipe and I'll lite my artillery piece with that barrel burning VihtaVuori N 560. My computer simulations indicate with Richards new 300 gr. 7mm (BC 11.12345) and a MV of 7,893 FPS I can get more people upset than any other post /ubbthreads/images/graemlins/smile.gif
