A guy I went to the range with last week had one, I did not care for it. What I have found is that when you start strapping the gun down and clamping it and doing all this crap to make it an immovable object, it shoots completely different than from the shoulder. POI can shift dramatically. You don't really engage lead sleds with shoulder and check weld, its more a benchrest thing where you try to get sight picture and trigger control without touching the gun (for some folks).If any of you guys go to mom n pop gunshops often, If you see any 450 marlin brass, can you pass the info to me. They want like $200-250 for 50 new cartridges on gunbroker. It cost more than buying the ammo........ Might be getting a lead sled and shooting my own brass.
Anybody own a lead sled? They reduce recoil alot? Part that touches your shoulder don't look too friendly.
What I have done in the past on guns I refuse to subject myself to on a bench, besides just adding weight to the gun (which again can change the POI) is use a continuous loop (cargo strap might work) and loop it around a heavy front rest and back to the butt stock to take the recoil. It worked good enough and I did not see a big difference in the POI.
Are you running a brake?
