When in doubt you can have any load tested for both pressure and velocity for not that much money. I've done this for many different loads over the years and once I have a load I can use if without worry. Some loads were fine a a couple were not. No surprise in a reload is a good one. I'd rather spend a hundred dollars to know my load is what I want than just guess. Fingers are fairly expensive to restore to function and few things make me want to cry these days more than a new crack in the stock of one of my guns.
