This is what I would spec, just for you:
- 35 lbs, so its nice and stable for barricade benchrest and mitigates the harsh recoil of a 6mm. Look into Galena based weight kits.
- A 6mm that's designed to go really fast, but loaded really slow. This way you can watch trace without getting any of the ballistic benefits of a fast 6mm projectile. Think overbore 6mm capable of 3200 fps loaded down to 2700 fps. You also get to support the economy by constantly buying barrels.
- A single stage trigger with about a 1 oz pull, so you can slap the shit out of it and get each shot off faster. I think Jim See even has a trigger slapping course you can take to maximize the benefit of that 1 oz pull. Best when paired up with his free-recoil course.
- Make sure to put a tuner on it. A tuner will allow you to skip the entire load development process. Or to make 1+ MOA factory ammo into an 1/8 MOA shooter when you feel too lazy to reload. It also allows two projectiles traveling at 100FPS+ different MVs to land at the exact same spot on the target, any distance, guaranteed.
- A giant brake along with the tuner. Tame that beast of a 6mm. The more ports the better. I would aim for at least 6 ports.
- Pick whatever the current "bougiest" stock or chassis is at the time. 80% of PRS is about how good you look while doing it. ROs are also more likely to aware you "style points", which is necessary if you want to get to the podium.
- Obviously an Impact action, because they are 1000% percent better than any other action at barricade benchrest. All the jersey boys shoot them so what else do you need to know? Anything else may as well be trash, Impact is that much more gooder.
Doing the above will guarantee that your dick gets sucked at a PRS match* (see disclaimer below).
*No guarantees it will be a girl. It will almost definitely not be a girl. Consult your doctor if you have the sudden desire to wear a jersey with corporate sponsors, or develop sudden onset of aids.
