Take
Captchee's excellent advice... he's
absolutely correct. I.E., if it ain't "broke", don't fix it !~!~!
The probable reason it's 'way too tight is that the smoke and "crud" from that priming powder burning in the powder pan has gotten into the threads and made them even tighter than the possibly "heavy-handed" person who initially screwed it into the barrel. Thus it's gonna be "fun" to turn it back out and replace it.
Be SURE to use a screw-driver that
EXACTLY fits the slot (width-wide) and try to use a screw-driver which has a blade as long as slot in the part to give you the absolutely BEST "fit" of the screw-driver blade in the screw-slot. Too narrow a blade on the screw-driver and you're likely to "rip-out" the slot on the part. Then, you'll have to
DRILL out the old, worn-out flash-hole which might ruin the threads.
THEN you'll have to re-thread the hole to screw-in the next threaded part.
As you can see, a poor job of it simply increases your frustration and work-load... and you can see how much MORE you may have to do. All of this can probably be eliminated
IF you use a screw-driver with a proper fitting blade and PUSH the blade HARD into the screw-slot while you're attempting to turn it. Hopefully, you can "break" the stuck part loose and successfully turn it outta the barrel and replace it ONCE it becomes necessary a year or many years from now depending on how much you shoot and how "hardened" the part is that is concerning you.
Just don't put your other hand just on the other side of the rifle
behind the rifle's flash-hole and barrel. If you do and the screw-driver 'slips"... you might end up with a hole in your other hand with the screw-driver sticking out of it.
Don't ask me how I "know" this about the screw-driver through the hand stuff... 'CAUSE I ain't tellin' !~!~!
Strength & Honor...
