Well when I unplugged the hole the foam expanded right up the the end of the chamber so there was foam all the way through....completely filled from front to end so there was no gap or bubbles. I did it twice and let it sit for a good 15 to 20 minutes each time. Are you going to tell me I did it wrong now because the gun wasn't up side down or side ways.lol. You guys are killing me, lol...give me a brake. I hope posters don't believe everything they read here.
Whoa, hoss. Always more than one way to skin a cat, if it works for you, carry on. No need for ruffled feathers.
It's easy to keep foam out of bolt guns using a bore guide and/or proper size tygon tubing to seal the breech and attach to can. Even the cheaper bore guides seal chamber sufficiently to prevent foam leakage into rifle action:
I like the Gunslick Foam as the can has a spout which slips into most bore guides snugly enough to prevent foam leakage.
Muzzle angled very slightly down insures no foam will back up and leak into action while soaking. A steady buildup of foam at muzzle insures no air pockets remain in the bore.
Oh, it's not necessary to keep the gun upside down unless you are cleaning a gas gun with the port located on bottom of bore.
