i have around 100 rem cases that i have dedicated to my black powder shooting. the most recent fooling was soaking them in suddsy warm water for a couple days and i dunked them rit into the water rite outta the chamber.
so after finishing the washing and de-priming and cleaning pockets then letting them girate in the vibrator for a few hours and so on i figured i would size them becouse i hadnt done so for awhile and i have shot them in 3 different guns so i was going to dedicate some cases for a particular gun and keep them paired up.
upon sizing them tho i noticed that some were easy and some werent so easy...also i observed that none were in need of trimming so i finished them and allowed them to set overnite. then the other morning i went out to load my fav 68gr load with the felt wad op wad. upon compressing the wad n powder for the seating i began seating my lyman 520's in the case and i also wanted to crimp them over the top band for consistant preassure. upon loading the first one i see that the boolit jumps back out of the case upon the downstroke of the press....after four of these i stopped to try to figure out why this was happening.
upon meassuring the id of my cases i see that they are .4575 dia. meassurment of my boolits come in at .458 average. so i tryed to finger seat and walla...they slid rite home with the trapped air shoving them back out as soon as i released the boolit. on holding the boolit in for a 5 count...they stay where i want so then i finish the seat and crimp.
i then meassure my other 45-70 cases that i have sized n primed n ready for loading for my marlin [ the non bp cases]and they meassure .4565 id the same as the inside dia die that i use for belling the mouth.
so the longwinded question is this...have i workhardened my bp brass with shooting bp in them and dunking them instantly into water? is this why there seems like no elasticity in the brass in that they wont seem to size and retain the sized configuration? will annealing bring them back to the new like sizeability that they had at one time?
can someone remind me of the oven style annealing procedure? im gonna go search for the procedure but if it is easy to explain then id like to hear bout it here
thanks for staying with this longwinded explanation....:groner:...[smilie=b:
