For the caliber and velocity, you can match these easily with cast bullets. Use a good lube, like Felix, LBT Blue, or Tom Grey's mix, and you will have the velocity and accuracy you are accustomed to. I use Felix, and shoot several chamberings in the 2250-2500 fps range, including Hk G3 class weapons, with no leading, and good accuracy. No fouling in gas ports, either, by the way.
Pressures would be less, as cast bullets are "slicker" than j!%@%ted bullets. You may need to temper the bullets, which is easy, even if buying commmercially, or ask for a Brinnell of at least 22 from the vendor. It's probably better to ask for harder if possible, because they will soften with age unless stored in a freezer until you are ready to shoot them. Then check the hardness when you get them, and the diameter. 22 Brinell should take you up to the 2500 fps range with a properly fitted bullet and good lube. Anyone telling you that these velocities aren't possible with cast haven't shot them much. I know of posters on this page that will take your bets up to 3000 fps, and happily take your money home with them in various calibers.
This chambering will handle a velocity of at least 2400 fps with out leading, and good accuracy, assuming proper bullet size. I imagine if you dropped on down to Veral's page and asked him, he would most likely tell you, you can shoot at velocities with cast that will scare your shoulder! Actually, with a good lube, you could very well surpass factory specs by several hundred FPS, with no extreme pressure signs.
