I grew up reloading and varmint hunting.....and yeah....ive had two plus 4 MOA rifles.

A 94 Bigbore in .307 bought new. And a minty 742 carbine.
742 would cold barrel put the first shot 1" high at 100 honest yards LoL.....but the next few from the now hot bbl into a 1.5" group,.........seven or eight inches lower than the cold bbl first shot

It was repeatable.

Oddly.....the two beater 742 regulars i bought later were 1-2 moa with no heat wander.

I guess theres a pretty good explanation of why they were worn and my carbine was minty LOL.

Shame....that carbine was a cool rifle.
