I think your best bet is to shoot your gun in 3 rd increments clean on a new target for each group. You can put 1' pasters or whatever you like on a board @ 100 and shoot groups till you see them tighten up and "settle in". This is likely to be in 10-20 rds but some barrels may take more. Once you figure out your sweet spot as far as proper rds of fouling just make sure you have that many rounds through your barrel before you hit the line. You are right, about 1 moa being a lot @ 5 if the tgt is small. As far as literal temperature, find the sweet spot, and shoot a group after it is cooled down. I doubt you see much shift on a good gun hot or cold.

If I may.... This whole cold bore fallacy is way overrated & less about temperature than it is about having a fouled barrel. Now if you have a bad bedding job tempurature will be an issue and your groups will walk as things heat up. In a rifle with good parts and fitting I have never seen a true cold bore shot (clean barrel) more than 1 minute out & in my experience it is typically reliable. I personally try to make sure I show up for everything with a fouled bore (to include the deer stand).

Maybe your load length needs to be lengthened....

In my personal experience and that of shooting friends (the main 3 being chips ahoy, wilson & Tripp) I like Cobra Mags. I havent had to modify and dont know of anyone else that has either. Chips Ahoy suck & I have seen guys literally throw them away, I would not recommend them to anyone unless I wanted to see them lose a match, lose money or just mess with them. Wilson's seems pretty deacent. Tripp Cobra Mags, in my experience have been THE most reliable (& not just in my gun) but those of other SS shooters in real matches bringing some heat.

well said

Are you sure about that?

I seem to have the same problem, if I dont feel stress I dont shoot so well.

Tripp

U.S. Marines nor Army teach sticking that much finger in. Its all 1st joint and up. TheKnight is right about the hi-power guys doing it though.

Tripp Cobra Mags

DILLON Carbide PERIOD

I agree, its a good program
