Shoebox, your gun plumber is obviously covering for his lack of skill
I personally like the 36" pipe length myself. After all, if you're going to be out shooting all day you don't want to wear yourself out!!!
I'm with you on flat primers on the boltface. The secret is to keep cramming enuf go juice in the brass until the primers just fall out when you pound the bolt open with your hammer to eject the case. And Wallah! You've just eliminated the tedium of having to remove those pesky primers. The brass manufacturers have been making & selling me some really defective stuff. The darn things don't want to keep the primers in after the first load. Luckily I one upped em. See you start with a small primer case & when it stretches out after the first firing, you can pound in the large one for the next reload thereby doubling your brass life.
Always happy to share my super duper long-range secrets.
