    Default Rifle Barrel "PORTING".........and "ARCTIC GUNWORKS" Experiences....???

    Two questions looking for advise.

    1.) Any experience with ARCTIC GUNWORKS in North Pole, Alaska......???? (If negative please sent me a Private Message....???)

    2.) Any recommendations for quality Rifle Barrel Porting.......???

    Thank You, I am wanting to have my RUGER 77/44 ported (And likely cut and crowned to 16")

    The rifle is a 375 H&H Sako Kodiak, the ram is plasma cut steel, my wife got me as a gift.

    I imagine Steve got it clarified in his PM, but the only "Arctic Gunworks" I'm familiar with is in Fairbanks, not North Pole. Are we thinking of the same shop, or has he moved unbeknownst to me...?

    Edit: (there is an "Arctic Firearms and Gunsmith" listed in North Pole)...

    I know nothing about them, I simple did a search for "Barrel Porting" and it was a company that came up. Here is the website: http://www.arcticgunworks.com/main_pages/shop.htm

    NOTE: I no Zero about them, just looking to get me 77/44 ported for my old'age years.

    That's Gary Junk; looks like he's moved from his Kalakaket St. location to North Pole... I wasn't aware.

    That is Gary Junk, he has a NP mailing address, but his shop is in Fairbanks.

    I've seen a couple that Stan Jackson did. Looked first rate...never used him personally.

    If you want actual ports cut directly into the barrel, then Magnaport is the way to go. They are done using EDM, or electrical discharge machining. This method produces the cleanest ports, and will not, generally, affect accuracy or velocity to any measurable degree. Having someone use a drill bit to drill holes in your barrel is, in my opinion, a bad idea. The bit will almost invariably leave burrs around the edges of the hole on the inside. Also, most of the people doing this will "counterbore" the barrel, thus removing the rifling for the length of the "ports", effectively reducing the usable barrel length by 1 1/2 to 2''. They then use a boring bar to create a new crown down inside the barrel at the end of the porting, which produces a very poor crown. That in itself may significantly degrade accuracy. Just my observations.

    Agree 100%. If you port into the bore there are only two good ways to go about it, EDM or laser and neither are equipment that a general gunsmith is going to have. You can't effectively de-burr inside of an existing bore so just say no to drilled or milled holes in your barrel.

    EDM and laser remove material by atomizing it away so they can't add it or move it to where it wasn't only evaporate it away from where it is. EDM machines are not cheap but still like 1/10 the cost of a junky laser machine so I don't think anyone is laser porting yet but I bet it's just a matter of time.

    Now a muzzle brake or other device that you add onto your barrel is another story, here we have the opportunity to clean up the bore after cutting the ports because we are not working with an existing finished surface like inside a rifled barrel.

    Anyway if you want your barrel ported just send it to Magnaport, that is absolutely the best value for your porting buck! If maybe you would conceder a muzzle device then that can be done by any competent gunsmith and will do a better job at mitigating recoil.

    I would opt for a better recoil pad or even one of those mercury recoil reduction devices before I had a barrel ported on a 44 mag, simply due to excessive noise (to the shooter) and also the limited amount of recoil generated in that platform to begin with. if you do decide to port the thing, I would suggest you leave the barrel at 18" so that if you decide (as I did with a ported Marlin guide gun) you don't like them, that you have enough barrel left to chop the ported section off and recrown.

    By no means or at any cost allow Gary Junk of Arctic Gun Works to practice any machine work on any firearms to include a Daisy BB gun.
