tried sizing and well yeah ... i cant get the fpb's into my barrel any way i try??? damn near put all my weight into it..... tried a few hard wacks as well? ???? how hard should this be?

the skirt measures .509 to .510 the powerbelts measure .508 but they are soft as you all know.. going to range with some more powerbelts i picked up the other day... just to work on shooting 100 yrds only since i am having a tough time seeing/aligning open sight on the bottom of my 6" black circle (6 o'clock style)

also shooting the 22-250 after a solid few hours of cleaning the copper fouling out of her.... it will be nice to see the clover leaf at 100....
