Need pressure schooling !

[SavageMark]

If you dont have a borescope you can feel it. If you havent addressed it just assume you have an awful one and clean accordingly

I only use cloth patches around a nylon brush . Is this sufficient ?

Ditch the nylon brush and use bronze with no patch.

Does a fired case go back into the chamber. Does it produce hard extraction?

It fits back in chamber but tight . No hard extraction .

I have spoke to two premium barrel makers and they told me a bronze brush ''used properly'' won't hurt your bore. So no worry's.

My wife was a having a difficult time opening bolt .

I do also with a Savage 223. May just be the camming action that opens the bolt?

Let me explain this , dusty means don't use the patches with the bronze brush ,you will need patches .you can use the nylon brush with kroil and jb to short stroke the throat but be careful . the mark show on the bullet is not from engaging the rifling ( jamming ) I would agree it's a carbon ring . good luck dave

I read where u shouldn’t reverse a bronze brush in the bore . How do I just do the throat without reversing direction ?

I’m just trying to learn something here the mark on the bullet looks to be a continuous ring is that the difference if it was jamming in the land as you would just see spots where it hit the lands

You use your jb or iosso on a patch to short stroke. Use the bronze brush in your normal cleaning regimen and itll keep this from happening so soon. Ditch the nylon brush alltogether. Ask a barrelmaker how abrasive nylon is. Or ask a fisherman if fishing line will eat up a propshaft thats way harder than a gun barrel.

I understand perfectly . I only use a nylon brush that’s covered with a patch . An old school friend of mine does it that way so I followed suit . From what I see some people clean with chemicals and some with elbow grease . I’ll stop tomorrow and get a 7mm bronze brush . Is Carbon blaster in a spray can good enough to use ?

I thought you had a 6.5? You wont get a 7mm brush thru there

I have 6BRs ! What brush should I get ?

A couple guys recommended 1 size up , so I guess 6.5 ?

No you cant even get a 6.5mm brush thru there. You need a 6mm brush and a real good boreguide. Still takes a heavy hand to get it thru there

Buy a dozen good bore brush, you don't want to try to clean with a worn out brush. Strip the bolt to check brass fit.

 

[comagutsa]

yep scrub away back and forth .. you wont hurt the barrel, then let chemicals sit in the barrel and do its work before patching out.. sweets about 10-15mins max ..boretech eliminator i let sit for 15-30mins before i patch out .. and yep 6mm ..you will only get a few cleaning out of a bronze brush then you will feel it easier to scrub barrel so throw it out

 

[J F Johannes]

You need this jag for the JB. Wrap a 3 x 3 inch patch around it.

Clean out the chamber with #9 or kroil .. Patch dry
Bore tec will cause stickiness if not cleaned out well.

View attachment 1121694 View attachment 1121695 View attachment 1121694 View attachment 1121695 Savage 12 action (with corresponding heavy Savage bolt lift) Shilen 6BR Barrel . 107 smk , 30g Varget . My wife was a having a difficult time opening bolt . You could feel fired case causing pressure again the bolt . So me being a genius I increased headspace from .001 to .004 thinking the extra room would help . It didn’t . Even a powder puff load of 28.1 made brass .004 longer and give a small sticky opening . Im enclosing 2 pics . One of fired cases and one of a mark all the way around bullet just from chambering . Any opinions greatly appreciated . Thx

If all your seated bullets leave a ring all the way around like the one in the picture, your throat may have too small of a diameter for that bullet. You are not even reaching the lands.
