RinB,
Manson (or one of the guys who works for him) did this 35W reamer with a tighter neck diameter and about half the normal freebore.
It shoots great, not sure it's any more accurate than my SAAMI rifles when they are at their best, but I don't have the powder compression issues I used to have. I get slightly flattened primers with every factory round I've tried in it, velocities are high but not over book max.
Spoke with Manson and JGS today. JGS no longer stocks 9.3x62 reamers... you can buy will either the standard one or a modified one from them for the same price. Manson stocks the SAAMI/CIP reamer but having looked at the print (I guess SAMMI/CIP is a 1.28" throat?)... I think I'll make one with a shorter throat.
