Thanx again everyone,I just got back from a test fire for pres.And still need to come outta it some.I'am clear down to,43.0and 43.5 grn's of H4831 with still a little pres.sign's pri.'s are still a little flat edges are a little rnd noe ,no dishing(or cratering) whichever you prefer to call it.I like dishing.So what I'am gonna ld up is 2 at 42.0 and 2 at 42.5.Then see if I can hit any paper eventually.It's been such a wet spring so far it's hard to go to the range.As I don't like walloring in the mud.And I belive 50,52,54,000 saami is the same if it's with 48 grn.'s of powder or 40 grn's,So when I have nice rnd. pri.'s no flatening I should be at about 50,000 I'am sure.And these old Arisikas will take that easy and way more According to ole P.O.Ackley when he done test's with.Said he could seperate every action except the Arisika mod.38's.So as long as I'am at 50,000 with a 140 grn. I should be getting about 2700 or there about's with it it only has a 22" wish it had a 26" or 28".And As OL'JOE.Said about them rechambering the old orig. 6.5X50 to 6.5X257 is for sure according to what I've been told and were billed as a very accurate target rnd. for it's day.So should be able to get 3/4" or 1" anyway.It's very nice looking ole gun someone reblu'd it in the 50's I'd say old style bluing,Some one work'd the military trig.and is not bad for old military,and someone work'd the claw so you can put a shell in the chamber and the claw will pop over just like a great ole ruger 77.Well this is plenty long enough post ....GOOD SHOOTING and HUNTING
