[QUOTE="Bart B, post: 107205, member: 5302"] I'm not a fan of nor a believer in compressed loads. Whenever one uses compressed powder charges, they run the risk of breaking powder kernels down to smaller pieces. Those smaller pieces will burn faster than normal kernels and change the pressure curve in a dangerous direction. If I was that Hogdgon tech's boss and learned he in fact said what you said he die, I'd have him on the carpet. There is no consistant standard about how much compressing any powder can take. He may have made Hogdgon liable for any dangerous thing happening. If there's not enough room in a powder charged case to hold the bullet without compressing (crushing?) powder, four solutions are available. One is to use a drop tube. One about 6 inches long works well and the added force of the powder going into the case faster will more compactly pack the powder inside the case. Drop tubes are available from virtually all reloading tool suppliers. Another is to put a loading block of charged cases on a table top, cover their mouths with another identical loading block upside down atop them, then tap the side of the loading block several times gently with a light hammer. This settles the powder deeper in the case. Or just cut the powder charge until the powder comes right to the base of seated bullets or use another powder whose safe charge weight does this. And finally, if you have to use the charge weight that compresses the powder, have your chamber's leade/freebore increased so you can do it safely by seating the bullet out further. [/QUOTE]
