Wow, what a wealth of information. Thank you Bart! Thank you Erik for doing these interviews. There is a lifetime of wandering around ranges asking questions in these interviews.
Talked to Bart several years ago at the Supershoot! He was very kind and invited me into his trailer while he was prepping and reloading for his next match. I was just a spectator but he took the time to talk to me! I do use his bullets in my PPC and BR. I’d like to hear more from him! Thanks
Thanks Erik for another great interview with a knowledgeable shooter. Also thanks Bart for allowing Erik to interview you. I have 1k of Barts 105’s that I hope I’m able to load and shoot them at 600yds to their full potential.
Really great interview, EC. I liked the style in this one. Bart, great to hear from you. As an F class guy it's really interesting to hear about the BR world.
Bart pretty much told us everything that is needed to be successful in short or long range shooting. But from starting the journey to making the BR Hall of fame is a lot of work and a HUGE amount of dedication. I am very happy to have met Bart and can call him a friend. Joe Hynes
@Bart Sauter Thank you for sharing some of your wealth of information. My 6BRA loves your 105 Hammers! Where do you get the targets you showed Erik that you use for your seating depth tests?
If I'm correct I think the measurement separating 1st 2nd 3rd was only .003 or so. . I started benchrest shooting last year. it's definitely a challenge to stay consistent from relay to relay.. CONGRATS BART.
I think most of the "don't clean" (technically don't strip copper) mentality can be traced back to the Magpul Dynamics Precision Rifle DVD's and Todd Hodnett telling people he doesn't strip copper fouling because of how unpredictable it makes your clean/cold bore shots. I stopped stripping copper out of my barrels after I saw that and since I really don't enjoy cleaning I happily believed that its actually better to not strip copper with chemicals and a brush and that running a few oiled patches down the barrel until they come out clean was the best "cleaning method" And I think the unpredictability of clean cold/bore shots really boils down to the fact that you are not actually getting all of your copper/carbon fouling out of the barrel. The unpredictability comes from the fact that the places that you are missing while cleaning changes every time, fouling left on the top of your barrel will behave differently than fouling on the side ect. And I will further suppose that the longer it takes for your gun to "settle down" after cleaning is the indicator that shows how much fouling you are leaving in the bore.
My factory browning 300 WM barrel was 3010ft/s for the first 300-400 rounds. One year I abused it a little (90 degree day) probably 15-20 rounds without much rest and it was hitting really high next range trip. It sped up to 3125 and required a 2g powder reduction to return to the prior node. Then it was all good. Maybe the needs mores just need a long string to speed them up. Factory barrels are not lapped to a 1/2 broke-in state(?)
@@SigmaBallistics Good call. I now have a borescope and I’ll check it out. I suspect your correct. I looked at some of the old primers and they were really flat…
@@patrick6087 you probably have a hardcore carbon ring in the end of the chamber/throat. Use a good carbon solvent (like boretech c4) with a nylon brush. if that doesn’t get it out just pick up some iosso abrasive (not the bore brite) and that will definitely get it out
@@SigmaBallistics well it had a lot of copper in it. I had cleaned it without the borescope and thought it was good. The borescope was about a year ago purchase. The barrel is pretty dang clean now, used Iosso and Barnes copper remover. Man it’s fire cracked… I’ll shoot it and see if things are better. Thanks for the input.
It would make sense to me that the perfectly clean bore may allow some gas to squeeze by the bullet causing a slow shot and then as powder fouling coats the bore it may seal better and cause a velocity increase
Just saw this, don’t know if I can get an answer but, when fire forming/ speed sorting brass, what rifle or barrel do you use? Can you explain? Is it a fresh barrel that this also serves to break in or an old barrel that has the same chamber as your competition rifle? This is a very expensive way to sort but it seems like the best by far.
Eric, has firelapping a new barrel and then molycoating your bullets fallen totally out of vogue? (NECO) Or been proven not to matter with the quality of barrels you use? Lockease is graphite, not as slick as moly, yes?
I just Watch this recently and found it verry intresting, Bart said he did not neck turn I wonder if he do neck sorting? Also I wonder the size of the bigger groups during 3 gun competition.
Erik you sure get way down in the weeds when interviewing Benchrest guys! Great insight to a world of anal thinking. I’m surprised the issue of lubing necks and bullets didn’t come up. Something I have been playing with graphite and Neolube2. Love all of your interviews, keep them coming and keep em small!
@@jakebrand9532 the thing is if they shoot for me the 100 that he could see me would turn it to 1000’s but hey not worried about selling me a 100 I can buy elsewhere vapor trails work fine
Example with toothpaste does not stack up as teeth enamel is actually regenerating over time. If this was not the case, toothpaste would do unbelievable damage as an abrasive. That is not to say that I think Ioso is damaging to barrel steel, just pointing out the 'apples and oranges'. Also your first shot is slow mainly due to barrel temperature. Cold steel contracts and there is more rifling pressure on the bullet for the same propelling force. Lockies allows extra lubrication in the bore until temperature raises (rapidly) and dimensions change (in micro amounts). Barrel contraction and expansion is something many people fail to take into account. Barrel being rough and speeding up through build up of pressure is just nonsense. Gas and fluid dynamics simply don't work that way
No. Once optimum barrel temperature is reached (max. reasonable expansion) and the biggest difference in temperature (between cold to reasonably hot) is bridged, the speed remains constant given the same consistent powder charge. Assuming of course fouling is not excessive. If you drastically overheat the barrel, speed will again change a small amount (lower). Try it with a good chrono. Steel expands at different rates at different temperature.
Tooth enamel does not regenerate. If it did, dentists would not have to fill cavities.Toothpaste is abrasive but the abrasives used are very mild. Over the life of a person the amount of enamel removed is inconsequential with normal brushing.
Process of remineralization is ongoing throughout a persons life. This is what I meant when I said 'regeneration'. Take a piece of shiny metal and use toothpaste on it twice per day as a polishing action, see what happens over time. Without remineralization, toothpaste would eat through enamel within a year, possibly even faster.

Holy s*** what an interview! I'm gonna have to go back and listen to this 12 or 13 times

Great interview Erik! Thank you Bart for sharing your incredible wealth of information.
Some of the most informative videos out there, luv'em!

That was a learning experience, excellent vid.

CONGRATS BART.
I wish this channel was on Apple Podcasts
Great interview.....I know all about that caddy business!! 🤣🤣
😂

did you borescope it? sounds like it needs a good clean

@@patrick6087 let me know if you shoot it soon
Great time , love it.

Good episode with Bart Chowder.

I’m surprise team Lapua doesn’t have a pit crew at these matches. What kind of small operation are you apart of Erik?
Making custom bullets ?
Eric, has firelapping a new barrel and then molycoating your bullets fallen totally out of vogue? (NECO) Or been proven not to matter with the quality of barrels you use? Lockease is graphite, not as slick as moly, yes?
Moly is no longer a thing.
On the topic of cleaning, what about using a 7mm in a 6mn bbl?
I just Watch this recently and found it verry intresting, Bart said he did not neck turn I wonder if he do neck sorting? Also I wonder the size of the bigger groups during 3 gun competition.
Please interview Sam hall , he is mr consistent for very long time
One of the most interesting interviews you have done keep them coming.
Love all your videos ....... some like pullin teeth ...LOL
In 3 years, I've never seen the flags where I shoot be in synch. They simply refuse.
Erik you sure get way down in the weeds when interviewing Benchrest guys! Great insight to a world of anal thinking. I’m surprised the issue of lubing necks and bullets didn’t come up.

I wanna try his 105 bullets but I can’t get them to answer my question on selling me a 100 to test with
He's 6 months behind with orders of full boxes. Not a real driver to sell smaller lots. Check on forums; they pop up from time to time.
@@jakebrand9532 the thing is if they shoot for me the 100 that he could see me would turn it to 1000’s but hey not worried about selling me a 100 I can buy elsewhere vapor trails work fine

So one shot gets barrel up to optimum heat in a matter of seconds? 🤔
