That seems to be about right. 147’s have a long bearing surface and showed pressure much sooner than a 140. RL powder and 2” inches of barrel should give you 150-200fps. That H powder does give great SD’s though!
Free bump. Wish I had the cash. I have the 3-24-42 non-illum and it's one of my favorite scopes. For a lightweight scope these are really hard to beat!
