too good to be true? throat "rejuvenating"

[hogan]

burnt barrel is burnt barrel. Stainless breaks, CM cracks. Cracked is smoother, doesn't lose chunks of material. Think pothole versus expansion crack in road. Hole grabs a bullet. Stainless not always the perfect solution

What have you studied about ceramics? At what temp does it need to be applied.
I think snake oil would be lesser expensive!

 

[lpreddick]

yes indeed, i would try snake oil if it reduced my cleaning time...i love to shoot but i do not enjoy cleaning a barrel. the original formula reduced my cleaning time, the latest is not as good.

Several years ago I applied it to a very woren 22-250. Well wore out is wore out and metal can.t be replaced. I also at that time applied it to my 22-250AI that was fairly new and was a 1/4 inch rifle. After the bore coat application it was then an 1 1/4 inch gun. A trip across the crony showed I had lost aprox 150 fps with what \i would think was now a smoother bore. Bumping up the powder chargep until I got back the original speed then brought accuaracy back but not to the original. I only use it now to coat the first 1 inch of my throats on new guns,and re-coat every 1000 rds. My tests so far(very limited) seem to indicate that it does slow the throat wear down cosiderably.

a long term followup: i spoke with mr burch yesterday re the failure of the dyna tek bore coating. he told me the formula change was a mistake...done to reduce cost. the product is now the older formula, so i will give it a try. my guns coated with the original still clean with minimal effort while my newer guns still require a bronze brushing to get out the baked on carbon. we shall see.

Where do you get the stuff? I shoot cast lead in my revolver and maybe this is the ticket.

Lprd, I tried it I a factory 243 and it did nothing. Do you think it would do any good to call the owner and see if I got the changed formula and possible if he would exchange it for the good stuff he is now selling again and what I thought I was getting.

brownell's has the product in stock...#100-006-145 Dyna-Bore Coat Kit at $44.99. i can only hope the current product is the old formula. when i spoke with mr burch he assured i was getting the "old" formula. the test will be to soak a patch and let it dry. the patch becomes stiff whereas the "improved" formula left the patch as soft as if not used. this mr burch is a nice person and listened to me as i described my experience. you can certainly call him and relate your problem...his direct number is 1-816-444-1255, ext 110.

The first shot fliers? Are they every first shot from a cold bore? Or are they simply the first shot after the initial application?

I want to do a couple hunting rifles, where first shot fliers make them into good tomatoe stakes.

 

[snowpro440]

Can you post pictures of your targets as a before and after treatment with the cold bore Flyer on your next few rifles listing the details ?

 

[butchlambert]

I have a few thousand targets. I can go through them and tell you whatever I want you to believe. ;D

John Barsness wrote an article analyzing Ultra Bore Coating (the original 'old' formula) in the June 2007 issue of HANDLOADER magazine.

High praise.
