[QUOTE="Brent, post: 53244, member: 99"] Tim, Glad to see ya still got your eyeballs!! I'm dieing to see a picture of the vent holes drilled in one, email me a pic if you can and I'll post it for you. I just can't picture where they're placed and such. I agree, the book max is often too high for some guns, so always start low and work up carefully. BOONYTOO, you got me thinking, I wondered how that ratio of velocity to pressure played out in the tests I've done on the Oehler 43. I looked over a bunch of test data for several guns and loads, just looking to see how much pressure jumped when a 50-75 fps gain in velocity was achieved. I found only a couple that only jumped 2500 psi, a couple that were only 3000 psi and by far, 90 percent of them were between 3500-4000 psi, a couple that were over 5000 psi. Most loads looked like they were about 3000-3500 psi higher at 50 fps faster. At 75 fps faster, they were almost always at about 4000 psi higher. Very interesting, it was real consistant across the board too, that's what I found pretty cool. [img]images/icons/smile.gif[/img] [/QUOTE]
