Is there a Fwt that doesn't heat up

Gotcha! interesting read, Bear!
What I do know here is I've had a couple rifles that just continue to shoot good groups of 10 or even more rounds. Tikkas don't have a super thick barrel. And I've got a 15 shot group from a Sauer 100 XT (ok thats a bit more substantial) 3 handloads in increments thats under 2"
BTW when I say "good" with the Tikka and 8-10 round groups I mean 1.5-1.6 MOA, but if you just say "oh, those were flyers" or shoot a 3 shot group, obviously better haha.
I've owned probably a half dozen featherweight barreled rifles. All heat up quick. As for heat treating, I've worked with it on engine blocks and locomotive frames, can't say I've ever seen it applied to a rifle barrel, but the theory should hold. - dan
Tikka does heat treat their barrels, but they're one of few.
Many bench rest shooters only use heat treated barrels. Mostly it's not needed for a hunting rifle, unless it's for a spray and pray type of hunt.
Yeah , there's no "culling" with said fwt my man, I'm not sure where that came from but since 2020, (big fires) I don't cull #### nor shoot FK all either.
Heat up quick to the point, will you shoot a string of 3 for a load development? Or wait in between for a while?
Mostly I do 3 round groups. Sort of gives me the best and worse, if those three stay within my limits (depending what rifle and which game), I am satisfied. For a while I was doing cold bore groups, shoot one, move to the next rifle, repeat. I had a lot of rifles at the time, and usually took a half dozen or so to the range, so it wasn't a long boring wait. I figured the first cold bore shot was the most important, with one follow up if required. Got some nice groups that way, though it took a long time. - dan
A nice Frost this morning, possibly the last of the year-?
I shot two loads. Two rounds each.
Superb.
130gr Corelokt re load.
And a 150gr Hot cor load.
There is 3 MOA difference between the Two, but I'm happy with that.
Will continue to repeat this same POI in future.
(My first shot of day to the R) So more a ME than IT worry.

And im almost getting certain that the heat is not helping me one i o ta .
this gun will never shoot 3 rounds in a row at Game, maybe 2 and a coup de grace scenerio - so im going to continue to keep 2 shot groups and cool circumstances , in the mornings an not so much in the afternoons where it is quite warm to begin with- for development

Factory stock barrels have never been to-my-liking, hence the year 2000. Short thin barrels will cause, muzzle-jump, additional recoil, rapid heat, less velocity, and inaccurate groups. It's been 26 years that I have custom barrels, all have the opposite symptoms of the aforementioned.

Just heat itself can effect accuracy of a barrel, with everything else remaining constant. The diameter of your barrel will Infact increase with heat, especially alot of heat. While this number may seem extremely small, it still does play on all the internal ballistics before your bullet even leaves the barrel. You might not notice it at closer ranges, but you stretch it out, and it will be more noticable. Everything changes at temperature changes, your coefficient of friction also changes dramatically with large temperature shifts. So alot more than just a stock touching or other rifle problems. Stresses built up in your barrel change with temperature, less if they have been stress relived but alot of barrels aren't.
I carried a 270WBY years ago for speed goat/ mulie hunting in southern Sask. It was a factory 24" #1 barrel. Very hot to touch after 3 quick rounds. First shot cold was always within 1" MOA. 3 shot rapid groups 2-3". As mentioned for hunting that first shot accuracy was what counted. Took this mulie at 500+ yards with that rifle, my longest kill shot.
you know when you have a moment of realisation- ?
i had one yesterday as i was just walking along near my shed, im not a very good shot on a good day- my targets show that story, but i dont miss and say f!k that was because it wasnt a 3 shot sub MOA load!
have shot a few now so definatly over thinking it - but realised its good to go and get amongst it
Got the Interbonds to print a nice group today on my Second charge attempt.
pretty much Max load of 4350, seated to the cannelure , in Nickel WIN brass - hot hard and going to be looking forward to using them on big deer in the future-
cold bore and then waited less than 4 minutes and shot again-
after that second shot, its 'hot' , without doubt. i tested this with some corelokt loads aswell.

OP, have you checked when you barrel is hot and when it is cold to see if there is stock contact? The FWT should have and maintain a full float. If it makes contact when hot that might be your issue.
