[QUOTE="elkaholic, post: 495369, member: 13833"] Hi guys....Most of you have probably seen the posts on my 6.5 and 300 Sherman cartridges. I have recently made a change which should be the absolute MOST case capacity in an '06 sized case and still maintained a good neck. I did this by using the 6.5x65 RWS case and moving the shoulder forward another .025" over my current case, based on the .270 parent. Not only will the larger volume boost the velocity a little but the RWS case can be loaded to higher pressures than domestic cases. I have read articles where they have been pressure tested at 70,000 PSI with no failure. I am having my current 300 rechambered to the new "MAX" case and hopefully my 6.5 soon to follow. This will be a simple fix by just running the current reamer in .025" further. Another plus will be cleaning up the throats a bit from the 1000 rounds fired through the old chamber. The only added cost will be a new go gauge a $27. My gunsmith said he could do the chambering in my B-78 for $50. My old hydro form die will work as will my sizing dies.
