So I discovered my Lee 7.62x54r boolit seating die won't allow boolits larger than .311 through the hole.
I guess it's a boolit guide.
Can I use a round file and remove a little material or is there a better method to open it up a little?

I have had the same problem with that die. I used some sandpaper wrapped around a drill bit on a cordless drill and lapped it out till my boolits would slide in and out. I size my boolits at 314. Just lap slowly and check the fit till you get it where you want

I think it was around 400 til it just barely went it then some 600 or 800 but not 100% sure

I opened my Lee 762x54R by coating a 5/16 wooden dowel (.311) with a mix of tooth paste and water mix valve grinding compound. chucked up the dowel in drill motor and opened die to .315. Worked for me. GP
