every company has the occasional dud.
Yes slugging the bore is a useful technique that’s not used as much as it could be.
Also, what are your three shot groups looking like?
Have not made it to the three shot group point with this gun. That's for guns that I already know shoot straight. That said, I did two groups of five last time out, and the first three shots set the extreme on one, and we're almost extreme on the other. So, over an inch for 2 in a row.
Thanks as does your overzealous appreciation for bullets that do not maintain their weight and fly into pieces. These are groups made by 2 of the barrels fitted to my Remington 700 switch barreled rifle. Yes both got the make it hot treatment. Obviously causing no issues.
What is really impressive is how many factory rifles today are tackdrivers. What you can get over the counter nowadays is something we paid good money for good gunsmithing in the past.
So heating and allowing steel to cool slowly is not a method of stress relief? Admittedly I doubt I get the barrel to even 500 degrees but I have seen this done by others. Tell me how exactly is stress relief accomplished?
To be fair, they have gotten better than they were 'back in the day'. But still, I'd wager that no more than 2 out of 5 off-the-shelf rifles are capable of putting 30 rounds inside a 1 inch circle, not even if you mounted them in a state of the art machine rest and fed them premium handloads. There are a few brands that are exceptions to that, but I'd give them no more than 3 out of 5, LOL.
Heck 3 out of 5! I remember when a factory rifle that consistantly put 5 shots into 1.5 inches was considered finely accurate. There were a bunch of 2" groups shooters people were happy with, nowadays sighting in using 2" group shooting rifle would have us fighting our scope adjustments. Bullets have improved considerably along with the processes used to make barrels. I wonder how many shooters are out there that could put 30 shots in a 1" circle over the time it would take to keep the barrel cool and shoot all those shots?
Stress relief happens in the red hot area not probably sub 500 degrees when you really have zero idea how hot it’s getting. Where did you come up with whatever arbitrary number of patches to push to stress relief it? Try 1000-1200 degrees for a heat treat. F class guys shoot often 20+ shot strings and do they talk about the ability to stress relieve their barrel? Absolutely not. If your tube has already been stress relived once and now it’s been bored, chambered, and crowned you can forget about making a meaningful difference. This is the most shade tree gunsmithing I’ve ever heard of.
Well then i am heating up the barrel for the pure joy of pulling the trigger. Getting a barrel hot and cleaning it can't hurt anything. By the way you should try it. Haven't seen any tight groups you have posted.
Funny it says something about getting steel hot and letting it cool naturally.
