Fer crying in the rain!!! Just go shoot the danged things. Don't waste any by worrying about a Kaboom. Focus your attention on bench technique, and see how well they group.
Lord guys, unless you set out to be stupid, handloading ammo is one of the safest activities on earth. Now, said, lots of members on this here forum do seem to set out to be stupid, but the OP is within book values, took reasonable care, and is shooting loads which can probably be found being shot on ranges across North America. Well, maybe except for starting out with premium priced bullets while learning the ropes, but hey, if you got the money, who am I to say how you should spend it.
OP, lighten up. No, really. If you read some of the hijinks the old wildcatters pulled, and died in bed of old age, all fingers, eyes and smiles intact, (deaf as a post, mind, but that is why we wear ear plugs for the one really significant danger in shooting of any ammo) well, then maybe you would just relax. Have fun.
Now, if later, you take the advice of those on board who suggest book limits are lawyer decreed, and get to thinking you can up the loads a wee tad over book "Do Not Exceed" limits, and think you can tell if you are over-pressure by any of a dozen old wives tales, well, then you are truly creating an unnecessary hazard when none need exist. In the between times, shoot, and have fun. Rolling your own is safe, gratifying, and lets you shoot more for your buck.
