The Lee scale
DO NOT LOOK AT THE SCALE !!!
The scale is just a guide line !! but if the bullet fits & the base is supported well where`s the lead gonna go if it does deform the bases ???? tighter against the barrel that`s where !!
Now if you have the slightest imperfection on the base or the bullet skids & opens the door for gas cutting all bets are off !!
If you can push a jag & patch smoothly down your bore you`ll do fine !!
If in doubt check the bore every magazine full to monitor foulin !!
Start at the bottom & work ya way up & the slower powders are more forgiving on lead projectiles .
