I have a bunch of Sierra bullets (Game King I think) #1835 140 gr. HPBT, Sierra's manual lists that bullets coal at 3.265 and although that will easily fit the magazine when I chamber a dummy round I dang near have to beat the receiver open because it jams the bullet into the lands and marks/scuffs it up. I colored the bullet black and when I eject the round there are 4 clean square marks where the color was rubbed off. I have re-colored and incremented the bullet seating down to 3.208 and there is 2 clean marks on the bullet now not 4.
Is this common for this bullet design ? and or rifle? Should I keep seating down further until the marks dis-appear?
I can provide pics if needed, I have some Nosler 140 gr. Ballistic Tips and I can seat those much farther out with no marks but Nosler does not provide col in their manuals just charge weights vs fps.
I full length sized the New (Winchester) Brass with RCBS small base dies.
I have never loaded for this rifle before.
