Went to the range yesterday and today to try and get things wrapped up for my wife Kelli and I's Mule deer hunt second season Colorado. After what we went through yesterday with her rifle. Ruger # 1 B in 257 Roberts, we were able to breathe a collective sigh of relief.
A little background on our struggles... I had tried since May to get a load, COAL combo with the Berger 115 VLD's and just couldn't get anything to come together to satisfy us.. Good velocity but nothing closer than 3 inch (at best and mostly worse) groups, I decided to try Nosler BT's, 115gr.. Loaded up a run of 5 loads starting at 47 gr Norma MRP up to 49 gr in .5 increments. 1st shot at the target yesterday and nothing.. couldn't see a hole anywhere.., so I suggested she shoot at the bottom target on the target board. Next shot was at the very right edge of the top target about an inch high of the bull... Wow.. 16 inches high.. Made the adjustment to bring the POI to the left and when I tried to adjust to move it down, I was only able to get about 14 clicks and the scope was tapped out of clicks.. We went ahead and shot the next set and the POI had moved to the center ,but still shooting about 13 inches high. Group was right at 1 MOA and velocity was what I had hoped for. 4 shots averaged 3180. Hmmmm, what gives? I had just recently ordered a new scope ring from Ruger for the rear mount so we could get the scope slid back for an easier eye relief for Kelli, so I suspected maybe an issue with the new ring..
Finished our day working with the Weatherby Vanguard 270 Win and some trial loads with the Hornady 145gr ELDX's. 1st 3 loaded with 47.5 gr Norma MRP and a nice group around 1.5 MOA.. not bad.. Next 3 were 48gr MRP and the group tightened to right at 1 inch.. Veloctiy was excellent, 3 shots averaging 3060 with 18fps ES..
Packed up and went home and knew I had to see what was up with Kelli's # 1. Removed the scope, rings, and scope rail. Interesting.. the scope rail was just ever so slightly bent upwards just ahead of where the rear scope ring attached, and the new offset ring made the rear of the scope even higher than before. I decided to lap the rear of the scope rail starting from just ahead of where it started its upward bend.. Worked it over with 400 grit wrapped around a 1 inch dowel and was able to get it to lay a lot better on the rifle.. next I lapped the rear offset ring and was able to get the scope level..
So today, we went back to the range to see if the problem was rectified.. Was able to adjust the vertical POI to where it should be.. after all the adjustment Kelli was ready to send a 3 shot group downrange to 100 yds.. Here is the result..
She was able to replicate this 2 times.. all groups running 1 inch or less.. Sure helped her confidence, and my nerves... :lol: :lol:

P.S. don't know why the pic is sideways, but I know it is a common issue..
