The matches I shoot are pretty friendly, so if one person has a laser range finder the data is usually handed out. With the accurate distances I will make try and memorize my holds really quick before the stage. My Steiner has a really simple reticle so I dont find memorizing it very hard. I am using Strelok Pro as a ballistic calculator and have tried to iron out the variables as much as possible. I have accurate humidity, elevation, and pressure, and BC's pre loaded. The only variable I am kinda guessing on is velocities. I have chrono'ed the gun one time at 2850 with 55gr American Eagle, so I use that as my baseline for .223 pressure 55grs. Do you think real 556 pressure 55gr would hit 3000 FPS from this barrel? As I stated in my earlier post I have 223 pressure 77grs on hand but the rifle isn't zero'd for them and I think they only make 2450 FPS based on the research I did.
My other option is to haul my 6.5 CM AR. This match limits shooters to 20 rounds per stage with 5 to 6 stages. I just dont have 120 rounds spare for the 6.5. I could chance it and show up with less ammo, but possibly have a better experience cause I would be flying real rounds at that point? I have ran out of ammo at a match in the past though and it was a terrible feeling.

I'd rather be shooting at 500+ with 77gr than 55gr. Velocity is a thing, but the 77s do so much better in general at longer range, both for general precision and wind deflection.
You can roughly backward extrapolate MV by tracking actual drop at a confirmed distance in relation to a verified point of impact at 100+ yards with a decent BC educated guess. Lots of dudes manipulate MV based off of claimed BC during truing and still do well in long range competitions. I have a magnetospeed, and I have proven that it is well within 10ft/s of truth, so I won't mess with MV, and rather manipulate the BC input to true.
Hey I appreciate everyone's contribution to this thread. My match is tomorrow, but I was able to secure enough creedmoor from bass pro, so I no longer have to worry about flying 55gr. Im pretty excited as this is my first time shooting my MSR10 in a match. I will post the AAR in the MSR10 thread that I started. I think the gun is finally ironed out.

The match gunner of the Faxon Firearms team used a Steiner P4xi to record some of the best times in the sport this year. The P4xi is an air gun designed for use at long-distance shooting events. It uses a 1:8 P&W match barrel and is choreographed at the peak of 2850 FPS using American Eagle 55gr ammunition. The result is a rifle that can shoot holes at incredible distances but still packs a punch when it comes to close-quarters shooting. Also, I tried to use 45 Auto, which is compatible with it.
