Figured out, not so sure about that really but I'm working on it.
This is a ProStaff BDC on new low mount Quad Weavers so from what you have said I'll leave it be for the time being. If I don't manage to pull the groups in tighter with either torque adjustments or the bedding blocks the Nikon goes bye bye.
The A-MAX really performed and let me know the potential of this rifle. The Bushnell scope wasn't dialed to absolute zero at that time, two clicks up and two to the left should have had it on the mark.
If I am correct an A-MAX (definitely a ballistic tip though) is what I took my deer with this year from what looked to be about 90 to 100 yards out. I had never shot this Savage 270 before and that deer dropped without taking a step. I hit high of my mark because the gun (I would guess) is ranged for 200 to 250 yards.
I have Sierra 168 Matchkings coming already and have seen the best accuracy through the Mosin with the Matchkings. From what I have read the 165 and 168s are right in the middle of the preferred bullet weights for the 1 in 10" bore twist in a 22 inch barrel. As well to go to a heavier bullet sounds to make a mess of the meat and my thought is they may wear the bore slightly faster, IMHO anyway.
The thing is, I know that I hit that deer well
I've said the same thing with an Elk I hit with a muzzle loaded 295 grain 50 cal. none coated Powerbelt from right at 100 yards. A very experienced hunter told me that we were on a good blood trail and had seen Elk drop with lesser blood trailing. About three miles later the trail went into some brush and trees and just stopped. I'm convinced aliens abducted my Elk!
Edit:
There was a point I meant to make mention of in todays shooting and had forgotten. The first A-MAX I went to cycle into the chamber from the magazine (I loaded 4 rounds into the magazine without loading one in the chamber) bound up when the bolt pushed it forward hitting the tip and likely flawed the bullets flight pattern. It hit three inches off the mark.
After that I took a quick assessment of the possibility of the o-ring I installed causing this. I found that there is a place somewhere between (just about right in the middle) the bolt contacting the magazine and the sloppy loose position of the magazine where the rounds do cycle without issues.
It seems every time I put my hands on this rifle there is something else that comes to light as an issue and as time goes on (it's only been a week today!) these issues are demanding a more complex remedy. I've actually invested in some barley flavored nerve tonic, something I haven't done since about Christmas time this year.
I think it's time to crack a beer and set this thing aside for an evening!
