22LR Challenge/Callout: Lithgow 101 and Eley Semi-Auto Benchrest Precision Ammo
Major Geek – JM Savage MKII Takes Us With Him On His Journey of Accuracy
Though my Savage MKII shot decent groups, I made the decision to try and improve upon it. The rifle was bought about 7 or 8 years ago for $235.00 so I did n’t think I was starting with much. As I made these improvements to the rifle, I took it to my outdoor range to determine if the work I did made a difference in its performance.
The first component that I decided to work with is related to the hang time, which is the time from when the trigger breaks to the time the bullet leaves the barrel. I wanted to extend that time to include trigger pull. The reason for this was explained to me by a world record holder, whose record still stands today, the Honorable Judge James Hinkle, who was my mentor. He explained to me that when dry firing, if your see your rifle move or even vibrate, this will cause your groups to open up when you are firing live ammunition.
So the first thing I did involved polishing the firing pin, making sure there were no machine marks, burs, or anything else that could cause friction of any kind. Of course, this will cause a reduction of only micro-seconds, but every little bit helps.
Next, I polished the bolt and installed an enlarged rubber bolt knob which I purchased from Amazon at a cost of $8.45. Using silicone as the lube and the glue to hold it on, this made the bolt feel better, more solid and smooth.
I also found a magazine from CSSPECS, costing $28.50 that assisted with loading the round into the chamber. It travels straight in, not at an angle that can cause bullet deformation. I used the 15 round magazine, and in my opinion it is far superior to the factory magazine.
Next, I worked on the trigger. I could not use the factory version because it wouldn’t even come close to what I needed. I bought a rifle trigger from Basix at a cost of $95.00. I stoned and polished the trigger, and installed a new spring set. The trigger now pulls precisely at one pound and is consistent.
I photographed everything that I have done, took the improved version to the range for testing, and posted the resulting target online. There is a measurable improvement in the overall average, which you can see for yourself.
Next, I will install the rifle in a Oryz chassis to determine if any improvements can be made.
Savage MKII Before
Mr. Revolverguy Comments:
Thank you Major Geek for the post I may even make some tweaks to my Savage MKII now. Though I am feeling bad, did anyone else notice the end of the post he purchased a Oryx Chassis I would say someone else has fell down the rabbit hole. Yes feeling awful about this NOT LOL. Also notice he started with a $235 dollar rifle, I keep saying it doesn’t take much. I will save a spot right in here on this page for you to be able to update us on the build and how things are going.
