by the mechanical means is a given prerequsite; however, to fine tune your reloads, get a set of Redding competition shell holders which allow us to adjust our cartridges up to about 0.006" longer head space without "clicking". Overbore;)

More Kaupphy!!!

Hope you know that joke-- Head space is also set by the length of cartridge head ( plane thereof ) to shoulder datum line of case. By changing shell holders you may/ can set headspace. Send me a PM if I can separate the black pepper form the fly __ it for you. I do this for my 300wsm's, 7.62 and 6.5's---;)
AS a last resort, here is verbatim quote from Redding:" The normal thickness for industry standard shellholders is 0.125". The number stamped on the top rear of the new Redding Competition Shellholder indicates the increased thickness over this standard and thus the amount it will decrease case to chamber HEADSPACE. . To select the proper shellholder for your particular firearm's chamber, start with the one marked +0.010. The (resizing ) die should be adjusted to just make firm contact with the top of the shellholder during the case sizing operation ( lubed case). Resize a case and try it ( unprimed and empty )in the chamber of your firearm. If the resized case does not chamber or chambers with difficulty, switch to a shellholder marked +.008 and repeat the process. Stop at he shellholder that allows the firearms's bolt to close freely. Your cases are now being sized properly to fit your chamber with a minimum amount of headspace." Now, aren't you glad you asked???
