lassie,
as much as i hate to admit it, these guys are correct.
calm down, take a deep breath, and explain to them how and why, it's possible to achieve these numbers without being so aggressive.

i am not the greatest speller or user of 10 dollar words, but a more calm approach, will get most here to listen.
my now dead machinist friend, talked like he just moved out of the hills, but, he was able to work for nasa back in the day, making apollo rocket engines, and after retiring, was so anal about his work, it took a long time to get him finish a project. good enough, wasn't in his vocabulary, it had to be perfect.

so maybe there is a connection between you 2 ?
i dunno, but calm down, and explain to these guys, calmly, and see how much better it goes over.

and as for quick load... well, book loads have come out as being unsafe using it, so go figure ....

only testing and watching for pressure will tell ya for sure when it's not safe. every gun is unto itself. why ?? i guess if someone ever figures that one out, he'll be rich right quick...

why is one load fine in one gun, but not another ?

that's the question i'd like answered.
