There is half a 22 long rifle difference between a 240 and a 260 gr, if you are shooting them at 1200 fps. --- In other words 20 gr isn't something to write long letters home about. Choose the largest diameter Dave offers if your gun is bored a bit large, whichever weight that happens to be, and use any jacketed data. Pressures will be far lower with the LBT bullet but velocities somewhere around 150 fps higher.
Regarding a visit to LBT. I made drop in visits off limits quite a few years ago, mostly because I do all the work, and I love to chat with any gun nut customer. So even if someone only plans to stay a few minutes, we get chattering and it runs into an hour or three of enjoyable diversion from work, which sets me back on production. And I definately don't have the ability to place a time limit on visits, so I've had to curtail all of them, especially with both my age and government hassles slowing me down.
