Howdy ; So I got a half brick of Sellier & Bellot 5,3 LP boxer primers . It says for rifle pistol or revolver cartridges .
Used a RCBS rockchucker ,universal primer arm with a tube feed . Primed winchester 45 colt brass But the pockets had to be clean to seat them down 2 thosands below the brass . The starline had clean pockets and the pocket was reamed with a lyman pocket reamer. It still took a very FIRM push to seat the primer and you had to watch for high primers if not pushed firmly to bottom . These primers are sharp edged and liked a chamfer to guide them in .
Shot them from a ruger with 18 LB hammer spring .One failure to fire but went bang on the second hit. Sorta shallow dent next to the federals . The S & B primers set off Alliant 2400 powder the same as Fereral 155 mags . No noticeably differance in the american select load between S & B or federal primer.
I will use the rest of the S & B primers in a marlin rifle 45 colt for silouette shooting with the starline brass because of the stronger hammer hit .
I would use them again if needed but would put a stock hammer spring back in the Ruger .
I primed some 38/55 winchester brass , these loaded smoothly with normal presure to saet them . I have not shot them yet ,they set 11 thousand below the brass . I will be useing just a starting load of Unique (Lyman cast book ) for plinking fun load .
I do wonder how well these primers would work in a progress press , could be tough .
Your milage may vary !
