Home Forums Lever Action Central Big Bore Levers Guide gun ported vs unported?

Thanks to all that replied to my post. I did buy an unported, blued guide gun and am pretty pleased with it. It was about six months old and came with XS ghost ring sights for $450.00 shipped, I think I got a good deal. I worked up a load for it using Hornady 350 FP at 1970 fps which goup about 1.25" at 100 yds. with a Leupy 1X4X20. Now I just need to let some blood with it. Thanks again!

I could not deal with the concussion and noise so I bought the unported 1895SS. Not as handy as the GG but more comfortable.

It�s certainly none of my business but if I could comment on this, if I could live my life over I would even hunt with some type of hearing protection. I am just shy of 59 and I have tinnitus, a constant and tormenting ringing in my ears. When I was young, I hunted and even plinked with no ear protection because I didn�t know any better. I would advise anyone to take preventative action against hearing loss and tinnitus. Nothing is worth going through problems with your hearing. Thanks�Bill.

Model 70 man;
I agree with you wholeheartedly. When I was young an invincible, I never gave a thought to whatever loud sounds I was exposed to, and now, well, lets just say I know what you talk of.
I probably lost most hearing to 30-06s and .357s. It never mattered a darn how long or short the barrel. Even a full 2' in 30-06 will box you right fine in a narrow canyon, and the .357 is rightfully notorious as a stealer of the ear.
It seems to me that muzzle blast/concusion has way more to do with pressure than porting, or barrel length. Having had ported guns, I'd say that they seem to help hold barrel rise down, but they only work well when the pressure goes up.
It is the pressure that makes a cartridge go from pop to kaboom, and even long, unported tubes report smartly when the pressure is up. Barrel porting may or may not make a gun significantly louder, some of that depends on where you, the bystander is in relation to the gun.
Regardless, everyone should use hearing protection. If you have a set of plugs that dangle from a lanyard, it only takes a short time to stuff em in. You'll be glad you did once your youthful excesses become the stuff of memory.

I've had my Marlin GG in 45-70 for about 6 or 7 years now, and have really enjoyed it. It's been my favorite rifle & calliber. I even got into handloading for it.
But until a good friend of mine sent it to Marlin for me to replace the barrel for a non-ported one,(Christmas present)i couldn't handle hunting with it without using ear foams. It would ring my ears out pretty good, when i'd shoot deer without them.

I still use hearing protection when range shooting, but i can now hunt with it without getting my ears blown out.

Killed this little fella a few days ago, with the GG.
