Perhaps this belongs in Rifle Country but I think reloaders are more knowledgable.
I have been reloading for about a year, but it's been a pretty intense year with a lot of work/study/experimentation. I have other rifles I've developed loads for that perform at a half MOA. For the sake of simplicity, can we eliminate the shooter or reloading methods as the culprit?
I have a Sako AV Hunter in .270 Win made in the late eighties. I bought this rifle used. The previous owner lightened the trigger and did a really lousy bedding job.
I made a variety of reloads using several different bullets (130's and 150's), several different powders, seating depths, different charges etc. I also tried two brand/weights of name brand factory ammo. In all I fired about 200 rounds with accuracy floating between 2 and 4 MOA. There seemed to be no rhyme or reason to the accuracy; i.e., I did not see it improve as I approached loads it liked - it didn't like anything and no pattern ever developed indicating I was even heading in the right direction.
I had a gun smith "fix" the bedding by removing all bedding one inch North of the recoil lug - that was his recomendation. I polished the bore with J-B Bore Bright and to this untrained eye the bore looks beautiful with strong rifling from throat to muzzle.
I took it out again today with 8, three round groups, 24 rounds in all, at 4 different charges spaced .8 grains apart, ending at book max load. Same flippin' results - 2 to 4 MOA. I had a friend shoot it too, he shot the worst group of the day.
I did notice something curious but need to go back to the range to prove it. It *seemed* like the fist shot from a reletively cool barrel landed closest to point of aim, with the second and third shots flying off badly. I would like to go back and shoot at three targets with identical load; target one containing all the first shots, target two containing all the second shots and target 3 containing all the third shots. Target one would contain all "cool" shots and two and three would contain hotter shots. Good idea / bad idea?
If the results are what I suspect, target one performing, by far, the best, is it time to chuck this Sako wood stock and get something better, thinking the stock is letting the action move around and/or the bedding is causing the problem? I don't know where to go from here with this rifle besides selling it. Any advice, direction?
The stock certainly is a beauty and I'd hate to get rid of it, but...
Thanks for your concideration.
If it matters I've used bullets from Sierra, Hornady and Remington and IMR 4350, 4831, RL19, H4350. I've used Wolf and Remington primers and Winchester and Federal brass. The last batch of handloads I also deburred the flash holes as well.
