Use a cast bullet .
Some bars loose them , some don,t ..... The little plugs that is .... I try to avoid Stihl bars if I,m going to be doing much fallin with that bar as they totally suck the power out of a saw putting in a face cut .. I was going to sell my first 046 Mag. because it was such a dud compared to my 372 ... the guys in the crummy asked me what bar I was running , told them a Stihl ... ALL 5 of them said almost together , ( Thats your problem ) . They told me to try my Oregon bar the next morning . I did , and discovered how good a saw the 046 Mag was .... Same chain , Same tree , .. The old stihl bars with the salmon belly and the small tip wern,t like that ...... I,ve been packin that 32" stihl bar around as my spare for 5 years now . If I loose it it won,t bother me much !!!!!!!!!!!!!!!!!!!!!!!
. Put a cast bullet in the hole and peen it with a hammer then dress it with a file . Works great .
