assuming any printed load is safe is beyond stupid.
ANY component change from what was used as the initial test can skew the data.
There is a reason that books suggest starting low and working up....
I bought some powder once, right before nationals, and it was a fair amount... around 10 jugs of 8 pounders as I recall...
It was safe alright with the same old load we had been using... but it was also 200 fps slower and you could not gain the speed without hitting pressure...
If it had err'd the other way around and I"d have blindly loaded it.....
OTOH I dont much care for non accurate barrels so I'm a bit picky about who I use for barrels.
You have to be careful on both ends of this... who you buy from and what you buy vs what you expect. AND knowing how to deal with reloading and reading pressure signs.
Above all I"m not siding here, I"m just making some notes on what folks should be applying when moving forward in building/shooting/reloading the AR for instance...
