    Suppressors Rotary Baffles - Opinions, Has It Been Done, Is it worth the effort

    If the impellers obstruct the gas enough, the bullet would be gone and out of the can before the suppressor starts to do its job. Static baffle suppressors do the same thing; they are obstructing and cooling gas flow long after the bullet is gone. I propose using baffles of superior design...

    Suppressors Rotary Baffles - Opinions, Has It Been Done, Is it worth the effort

    You bring up an excellent point, but bullet will have exited the suppressor before any movement occurs of the turbines. The orientation of the baffles after each shot is a very insightful point; the use of precision balanced turbines would hopefully render the point moot:; look at the balance...

    Gunsmithing Stock Bedding?

    This depends on a couple of variables, the most important being how heavy/long is your barrel and how strong is your action? I wouldn't hang an 1.250x30 cylinder off the front of a Remington 700, but i would consider it on a BAT or similar action that is stronger, heavier, and has a longer...

    Gunsmithing Heavy copper fouling solutions?

    Foaming copper solvent, let it soak 24 hours until the patch doesn't look like a Smurf, then get a set of David Tubbs' Firelapping Bullets and firelap the barrel. Or, if you have the change, have a custom barrel installed. Sent from my iPad using Tapatalk HD

    Gunsmithing The Kiss of Death

    Got my Armalite M15 A4 back from a gunsmith to have a thread adapter and SureFire 556 QD mount attached. Sent it off because the headstock on my lathe is too long to for a 20" barrel and I detest turning between centers because I can't indicate an erratic bore. Job looked good, set up a 3 foot...

    Night Vision Laser Genetics ND3 allows me to make cold bore hit @ 480 Yards

    Bitterly true. At least FLIR has gotten prices down to the cost of a good custom rifle, as opposed to a custom rifle range, and the green lasers are a much less costly alternative. And seriously, night vision is a luxury that most of us can get by without unless you have a security or predator...

    Night Vision Laser Genetics ND3 allows me to make cold bore hit @ 480 Yards

    532 nm green diode lasers such as Laser Genetics uses are obtained by passing the beam from a 1064 nm ND:YO4 or ND:YAG mid infrared diode laser through a frequency doubling crystal of KTPO4, aka potassium titanyl phosphate, so there could indeed be some IR bleed, but I have no idea how much, and...

    Suppressors Rotary Baffles - Opinions, Has It Been Done, Is it worth the effort

    OK, from Google-gu, it seems we are looking for a "open impeller", often used in pumps, with at least a 1/2" center hole. These appear to be ready made baffles if made out of the right material. And, as previously stated, I dont know that they need to rotate, although that would reduce any...

    Suppressors YHM phantom accuracy ?

    My Phantom performs very well on a number of my rifles, from .223 with the proper mount, to 6.8 SPC, 308 WIN, AND 300 WIN MAG. It hasn't adversely changed any groups with regard to size but it does change point of impact. You have to also keep in mind that hanging a heavy device such a...

    Suppressors Rotary Baffles - Opinions, Has It Been Done, Is it worth the effort

    All suppressors need regular carbon removal o maintain optimal performance. immersion in a carbon removal agent such as SLIP 2000 Carbon Killer in an ultrasonic cleaner is routine in LEO and military subgun suppressors; even if a bearing did seize, the turbine should still be a pretty effective...

    Suppressors Rotary Baffles - Opinions, Has It Been Done, Is it worth the effort

    Thanks: I've been trying to design this based on readily available parts, and a source for turbines readily availale has escaped me until your post. They are made to operate in high heat/high stress conditions under high duty cycles, so designing a baffle to protect them against the muzzle...

    THE Question

    This is sure to ignite a lot of "discussion", so let me say up front, I realize I am a very small fry in a Large, Deep Sea of experience, and I pose this question with great respect to those who are pushing the envelope. The question: Assuming you have a rifle capable of what I think of as ULR...

    Suppressors Top 5 Suppressors ( can of worms ? - Excuse the Pun)

    Truth. Reams of paperwork for a muffler. Let me preface this next statement by saying I SUPPORT motorcycle riders, but some Harley pipes should require paperwork due to their LOUDNESS. Makes no sense to me. Sent from my iPad using Tapatalk HD

    Suppressors Rotary Baffles - Opinions, Has It Been Done, Is it worth the effort

    I have read here and there about suppressors theoretical ( I believe it was theoretical) using turbine-like baffles that would rotate on bearings, possibly ceramic. The bullet would pass through the bearing center; the turbine assemblies would press on to the outer diameter of the bearing. A...

    im fed up with my .338

    I think there's a good chance your barrel is the culprit. Feed a tight, well lubed patch through a bore guide. Very slowly but smoothly advance the patch. I want you to see if the patch becomes easier to push through closer to the muzzle or loses most, if not all resistance as the patch...

    Gunsmithing Headspacing Question on my .375 Chey Tac

    OK, I see what you're saying. Yes, that is an entirely different set of feelings altogether. I've called him out on it on Facebook; last I knew he was unemployed in Anchorage, AK. Very. very hard not to wish ill will on him, but in the end I don't see where it would bring me any satisfaction...

    375 SnipeTac hangfires

    If it hasn't been mentioned already, I'd uniform the flash holes on all my brass, including deburring the inside of the flash hole and the depth of the seat - Ken Markle used to make a great set of tools for that. Some flash holes are punched, not drilled, and the burs inside will slow the...
