No problem. Let me answer your questions:
1) It was probably in the low to mid-70's when sighted-in the first time, but in the mid-80's when sighted-in out in Arizona at 100 yards.
2) Here is a direct link to the product in Amazon. I am going to do a review in the near future, since I am getting so many questions about it.
There are so many different thoughts on why some rifles are not shooting well, but the temperature issue might be well-founded. I wrote in one of my articles that the groups opened up the hotter the barrel got. The tiny barrel on the Savage may be the reason for this, but I am not sure. I have yet to shoot a bunch of rounds at a time out of my Contender (23" semi-bull barrel), so I don't have anything to dispute that theory. Your information adds to that theory.
The ammo is another funny thing. Some folks have great results with the 20 grain bullets (as do I) and others only have good results with the 25 grain bullets. I know each rifle shoots ammo differently, but this stark difference leaves me scratching my head.
I know this doesn't help much, but it is what I can offer. I would love to know some hard numbers on how many are having issues with their rifles. Maybe I'll put up a poll for folks to vote on?
