McGowen/Stevens 260AI by Kevin K

My post is for all those who are gun nuts in search of the holy grail of accuracy. Yes, some might think, Stevens…what is this guy thinking? For those who have not tinkered with one or have not shot a Savage/Stevens product it may come as a surprise. For those who do this idea will not. I began one day with the idea,” I’d like to play the F class game. “ But I was not going to convince the boss of a multi thousand dollar toy. I would have to think on the cheap, so I began my search all over the internet of ideas, guidance, and some good luck. The goal of this project, (besides the great fun in shooting it) is to find an answer to the age old question, “How much does one need to spend to attain competitive accuracy.” Well, that began the addiction to Savage/Stevens products. Here is my 260 AI as a result of a years effort and with the help from some fine CGNers. Thanks Jerry for great advice and service. PS, cost all including taxes.

How Well To Prechambered Barrels Shoot?

Oct 16, 2009 This is a very common question I get asked. The short answer is VERY WELL and it really depends on the quality of barrel used and the precision of the chamber cut. I just received a new Shilen SS Select match barrel prethreaded and chambered for the Savage action in 260AI. I put this into an older Savage action that used to be my 7RM LR hunting rig. Into my BR style thumbhole stock and off to the range. Below is a picture of the test groups I shot today with new, almost fireformed Win brass, Lapua 139gr Scenars, H4831SC, CCI BR2 primers. Conditions were near ideal with next to no wind, overcast, cool but damp (just rained). [almost fireformed brass – this brass was formed using a light charge of pistol powder and cornmeal and has the shoulder about 90% formed (still rounded shoulder). The first smokeless load performs the final forming and gives the case a nice sharp shoulder] After the first 6 shots to try and sight in the rifle, I found that the scope ring shims (Burris Sig Zee rings) were way off and I was shooting way too high. I forgot my extra shims so had to make do. Was able to get the POI on the target but still over 1ft high at 100yds. All testing was done at 100yds because I couldn’t keep on target at 200yds – POI way too high. A couple more shots and I was near the target and had run out of sighting in ammo so I had to use my first test load....
