thanks--was thinking heavier may be better...I have no experience with ruger or factory ammo.. thanks again marcMight try federal gold medal match with a 69gr matchking..... Normally shoot well....
Now this is my opinion and cost nothing but.... I have some experience with Ruger American barrels... I find a very very good cleaning and about 2 sets of 10 strokes of JB bore paste to help smooth things out then a cleaning again very helpful with the Ruger American even their Ruger American Rimfire... Sometimes maybe after shooting and a good cleaning again a few more passes of JB and another cleaning may not be a bad thing after that just fire lapping the barrel by normal shooting whatever bullets seems to make them come around... In my opinion you certainly aren't going to hurt anything and I have found great improvement on pretty much all factory barrels by doing it...thanks--was thinking heavier may be better...I have no experience with ruger or factory ammo.. thanks again marc
I have had a different a experience with two Ruger Americans I have worked with for a friend. Outside of Number Ones I have never owned a Ruger except one I aquired in a trade many years ago amd immeadiatly sold, it was a 77 HB in .243. Friend who packback hunts elk got tired of lugging is pair of old time Weatherbys around the mountians so he bought an American in .308. Called me said it shoots 3 inch groups, can you look at it. It had the worse moden era factory trigger I have ever felt. I took care of that and once the trigger was 3 lbs with a tiny bit of smooth creep and a bit if clearance given to the barrel in one spot it now shots 5/8 to 3/4 with several factory loads.He has killed 2 out of 2 bull elk with it neither going over 35 yds. Now he bought another American in .450 Bushmaster, or is it .458, it has a trigger very close to the one I fixed out of the box and shots about 1 1/8 At 100 yrs. Just fine for an in the woods deer rifle. He has killed several big body Mich. bucks with it. For the money, might not be the worse choice. Better then the Rem 700 Varmint in 22/250 another friend bought that would not shoot under 3 in groups with handloads that Rem returned to him after he sent it back and was told it is within specs. So, the pitted barrel, did you contact Ruger and what did they have to say? Among itrms you might check, were the scope base holes clean of metal scraps, be sure scope base screws do not bottem out, are ring screws tight, if you did not mount the scope youself check those items I have found problems even when mounted by , professionals. Be sure action screws are tight. I usually make the first one a bit tighter than the rear. I forget if there is a middle one, if so just snug on that one. Be sure barrel channel is allowing total clearance. After that glass bed the action and the backside only of the recoil lug. No bedding on front, bottem or sides of recoil lug. Last chance, try some shims at front end of fore end putting some varying degree of up pressure to the barrel.All the things learned in almost 60 yrs of acquiring accuracy..Thanks guys! I did not get to try anything today, gonna scrub them good and get the heavies shot when time allows... Thanks for the help marc
With a 8 twist, shoot nothing less than a 70 gr bullet. 69 gr maybe. it will like the 75-77 gr the best.
