I am the proud new owner of the second rifle I have ever owned, a Marlin 30 AS in 30-30. I recently acquired it used from a local shop and have not had the time to get it to the range yet. At the shop I was careful to inspect the bore (very clean with no pits or dings at the crown) and the action. Judging by the slight scuffs on the stock and scars from rough carry with a sling, this rifle has seen the field a few times. I did note before purchase that the rear leaf has been adjusted left (for windage?). I assumed this was either accidentally tapped out of center or perhaps an idiosynchratic adjustment on the part of the last owner. My real fear now that I've got it home and am cleaning and oiling it is that perhaps there is some basic defect in the accuracy of the gun. Now, I know there is no way to prognosticate based on this little info alone without actually firing some groups (if it will indeed group), but I really don't want to go thru the misery of tuning and tweaking the one lemon Marlin in Western NC. My first rifle was a 1955 336RC in 30-30 and very accurate every time I had the pleasure of firing it, thus there was no need (I thought) to learn about adjusting the old semi-buckhorn sights. Anybody out there have any advice as to how to proceed? I've been looking into peep sights and ghost rings to replace the originals anyway, but, here again, I don't want to go through the trouble and expense if there's an indication that it will not be worth it. Any replies would be welcomed...
