    Gunsmithing Krieger barrel fouling badly with Barnes TSX

    But regardless, in my discussions with customer I would put out the disclaimer: You do realize for foulness, barnes is a Saigon whore. So you're going to need to up your game on bore keep.

    Gunsmithing Krieger barrel fouling badly with Barnes TSX

    Used to work with barnes bullet combos a lot in a former life. If I knew the customer was specifically shooting x ammo, would contemplate with said customer adjusting the groove diameters to suit, and perhaps use more of the old school military throat with only throat and no freebore. Example...

    Why are Proof Carbon Fiber barrels superior to Christensen? BSF? Dracos?

    If Proof told you they wrapped specifically for twist rate, thats one thing. Otherwise I'd take being told with a grain of salt. Would it matter? They do have some equipment, but honestly I have not enough data to support 'mattering'. later

    Why are Proof Carbon Fiber barrels superior to Christensen? BSF? Dracos?

    do you mean the steel was bigger diameter or the CF wrap? If the barrel gets hotter quicker, it's probably a lighter contour steel substrate, as the heat will escape from thinner wall more quickly than a thicker wall. Remeber it's hottest inside the bore, as you add wall thickness it slows...

    I used to make the substrate steel barrels for place out of Minnesota, what was their name...Magnum Research, mountain eagle or summot..Funky stuff Later

    How were '03 and Garand barrels rifled?

    You should run a stress relieve op after pulling a button thru. Regardless if it's been broached prior. Hole is a hole. Hoop is a hoop. Moved material, didn't cut. Cold work, cold forming, or shock is usually what imparts stresses into steel. Bending moments, forming, dropping on the...

    How were '03 and Garand barrels rifled?

    Ha, no I was with you bud, just didn't cut to the chase.. Get it right and you don't have to rifle twice. They just as well go straight to button, but perhaps they had difficulty with broaches staying together cutting full depth, or the length of broach needed to go full depth precluded them...

    How were '03 and Garand barrels rifled?

    Missing my point. If you do it right to begin with, you don't have to go thru the struggle to make it right. Straight's straight, queer's queer. How I lernt the trad anyway. I did get to learn the straightener, only to learn it was a bellend on the neck, to make a crooked hole straight...

    How were '03 and Garand barrels rifled?

    Frank, I worked Europe for how long.. I don't try to figure out why they do things wrong. LOL Later

    How were '03 and Garand barrels rifled?

    sure, but it's last tooth that counts to finish size and form . and all depends on geometry.

    How were '03 and Garand barrels rifled?

    Yes. It's an internal broach. there are many types of broach machines around that will do a controlled helical cut. I have broach rifling tools from wayback that look very similar to the tool shown. I liked the straightener myself, similar to the coat rack I had back in the day. Later

    Gunsmithing 5R or 6 groove barrel

    Anthony, just a word of advice from an ex custom barrelmaker. When Frank answers you on the forum, thats when you go full PM with him, get an order placed, and start deleting your posts about wanting a particular caliber/twist/etc. BC now there are 400 people placing orders to get in front of...

    Gunsmithing Understanding barrel condition

    I like that, good idea. Borescope inspection in front of shop, barrel shop in back. perfect. Dave, how many times do you think I've stuck a borescope in a barrel by now? I have never seen an accurate barrel in a borescope. Seen plenty thru the dayscope. But it's definitely a tool I use...

    Gunsmithing Help deciphering bore scope pics

    Not sure if vintage Savvy, but probably better then .002" on both bore and groove otherwise the air gages mightn't fit. But I do agree in the what you think you see may not bee. Qualitative analysis measures what these things you see might be. Scratch and sniff profilometer testers can tell...

    Gunsmithing Help deciphering bore scope pics

    Ever see those visual surface finish gages? Look at those under magnification. That's where I started. 64Ra for some bores, 32 for others, 16 for others, min requirement surface finish on bores. Get a borescope, buy one of those kits so you can get some education there..
