I will tune for speed first, then check for accuracy. I will get all I can out of a gun speed wise as long as the accuracy is there. The quicker the pellet gets to the target the less chances of it being diverted by wind deviations, etc. Not too worried about shot count as I have my own in house air supply that’ll top off a tank fast. As long as I can get two magazines worth that comes with a gun, I’m happy.
If it means my regulators life is cut shorter than normal wear and tear so be it. These guns have to be maintained anyway, and as long as parts are available, I’m not critical about being too hard on equipment,
now, having said all of that, if I was to pack up and head to Arizona for EBR, I would favor dropping the speed for the sake of shot count combined with precision accuracy. Same if I was into field target shooting.
But for my current needs and current guns, a 30 cal 44.75 grain pellet at 930-950 FPS puts a grin on my mug.
