Thread: A word for the wise from the complacent

Accidentally loaded 162 yesterday rather than 150 didn’t notice until I picked up the brass I’d blown 3 from 5 primers, the kicker was my eyes were on the chrono as I was validating a load before ordering my cds and the numbers were perfect same velocity as the 150 even the same average sd I did notice tight bolt lift and thought I’d left a bit of oil in the chamber from a good clean looked at that brass had a good stamp but primer intact and continued teach me for having the lid off 2 box’s at once . If something doesn’t seem right chances are it isn’t stop and have a good look first mistake was wrong projectile second was assuming abit of oil left in chamber upped the pressure 3rd was shooting the rest.

Yep. Mistakes, they do happen. Always a good wake up call.
Glad you remain intact and are telling us about it.

Yep. I once, and only once, tried working up loads for two rifles at same time..... to save time. Ended up picking up the wrong tray of ammo and put a 6.5x55 through my 280AI. Now only the components I wish to use are on my bench when needed.

Load 1 thing at a time. Keep the powder bottle next to the scales and empty it all back into the bottle as soon as you're finished the batch.

At least it wasn’t a 7mm08 through a 300wsm. Mate owns a sports shop. Gets to see all the whoopsies.

Even with the wrong bullet weight, your loads should not be hot enough to trash Alpha Munitions brass.

What sort of load were you using for the 150's?!

For 1 grain over max I think something else is amiss, check your scales or powder.

Also note the 162 is a different shape and was likely jammed

I shoot both at the same COAL (2.8"). Unless you are doing something like a crazy 3"+ COAL I can't see how this happened.

Powders new 2208 bought new buy me custom chamber loaded to 2,935 scales are good against the beams can confirm it was jammed

I wouldnt have thought that was hot enough to blow primers with 162g. It's only a grain over max, even jammed. Still, I dont know your rifle.

Highly dependent on alot of factors. Assuming book max is going to be the actual max in any rifle is not a good idea. All it takes is a chamber with tighter tolerances than a sloppy factory and some brass with a couple grains less capacity than the brass used for the book data and all of a sudden your grain over max is more like 5 grains over. Short of having proper pressure testing gear, Velocity is always going to be the best indicator of pressure.
