Cold Bore Challenge

Just watched your first video. Nice shooting. Just wondering... Are you doing any follow up shots to see if you have a cold bore variation or your dope is off? Just a thought...
I'd love to do this if I could get to a range more often then every couple of weeks.

Keep it up!

Have not done any follow up shots.
 
I think follow-up shots are irrelevant to what you are doing or trying to accomplish. It moves away from what the original intent of the "cold bore" shot per day is. Just my .02 cents

Unless your data is off and you keep missing. But I see the value in what you are doing. Make the first shot count!
 
Man this sounds offly familiar to a challenge that I gave a few board members on a different site that was talking crap. Hundred bucks an all. I called it the "Coffee Can Challenge" But it was basically the same thing, 600 or more yards on a typical day, no calm wind bs. A typcal 5-15mph wind day as if you were out calling coyotes. It had to be a cold bore shot not a walk on target bs. It was one round per day per target. I'd set a coffee can out on a 4" piece of 1x2 pounded into the groud a foot leaving the coffee can flipped over the top of the 1x2 bottom up so it could also bobble with the wind. I have done this twice. The first time it was 635 odd yards, cant remember any more. One round, one hit. The send time i did it was just to make sure i wasn't lucky so i made it a tad further at 665yds or so and pounded another hole through the can. You know i never did get that hundred bucks!

This is a fun test to see what your rifle and what you can do with the right equipment.

Have fun guys.

Here is the 665yd can.

Actually, if he would shoot a 5 shoot group in succession and in the same time frame (so as to eliminate wind variables as much as possible) while holding the same point of aim it could be of quite a bit of use. But having s camera at the target might be necessary to make sure he catches the cold bore shot.
 
It's so addicting going out and shooting a new load, finding out it doesn't shoot, and then having to reload and go back to reshoot until it's perfect. Good luck with your Reloader 15 and those VLD's!
 
Wow. In the video it looks like you missed it by 4 feet. Guess you hit it though...
Where is your kestral when you're testing wind? It looks like you are shooting across a valley every time. Might want to hold it up higher, to account for the wind where the bullets trajectory is.
 
Thanks for sharing your outings with us. I need to get out and try some distance beyond 200 yds. Hopefully in the next few weeks.
 
Great videos, at our matches we don't get sighters so that first shot has to count. You're getting similar results that we see with our elevations usually always near perfect but it's really hard to get that wind call right especially shooting across valleys, tree lines, streams and fields and no way of judging it other than things floating across your field of view in the scope or the mirage.

Like these types of videos, great job. Getting a first round hit when dealing with Mother Nature in non-perfect conditions is tough.

Good luck with your testing

The last 2 days I have been shooting Berger 168 VLD's With RL-15 powder. And that is a load I have NO experience with. I am not blaming the results on that. But check this out

Here are some groups I shot after the Cold Bore shot with my original load with a 168gr SMK with Varget powder and the VLD RL-15


SMK< 5 shots each >VLD






Day #6 is uploading now
 
Are the better groups coming from Varget, or the RL15. I couldn't differentiate which was which group.
 
Nice shooting man! Told you those 168 VLD's are a bitch to figure out.:thumbup::D

Someone pointed out my case of Dyslexia, I said 8.5 mll and I dialed 9.5 mil.
Just went and checked my ballistic chart. and I should have dialed 9.5 mil. Guess I was thinking one thing and talking about another. haha
 
Nice shooting! All your impacts are to the right of center, you might have your trigger lightened a bit. Either that or turn around and shoot the other way...
 
I think he means put the gun where your target is and target where your gun is to see if it is you under correcting for wind or you tugging on the trigger wrong.
 
I think it was just the ammo and you pulling the shot. I shoot with you all the time usually you are spot on. Forget about the camera and relax just shoot like we normally do. Maybe try what bodywerks suggests to eliminate any doubt. Its worth a try. Wish I was closer then I could help by observing what you are doing like you always do to me. :D

I assume you are using a ballistics program? I assume it is set up to account for spin drift? I only ask because it is about how much off center you are and it is in the direction of the drift.
 
Switching powder and jacket material I've found isn't the greatest for finding best load with Bergers. Berger VLDs are really not a hard bullet to make work and work VERY well. Jump'em 0.040 to 0.060, start with a clean barrel (no SMK jacket material in bore) and find sweet spot. Might want to look at H4895 with the Berger 168 VLD, something a touch quicker in burn rate will probably tighten up the Bergers. YMMV and worth what you paid for it.
 
Very, very cool thread.

I should try it on my 250 yd, and 3" steel. Except my range almost never has any wind at all.\
 
I am using a kestrel with ballistic program built in.

Your right Biggerhammer50, Just need to relax and make it a good shot!

Another thing you can do is compare its input to that of another ballistics program. Its a useful experiment.
Also, use the g7 BC if possible, and apply different BC's for the changing velocity to get a more accurate trajectory.
 
BC affects wind drift just as it does drop. If the projected time of flight for the bullet isn't accurate the estimated wind drift will be off.
But you're right that wind will always be your nemesis. Its everyone's...
 
Man, I cant wait to start my own. Of course I dont have a place like that to shoot. My 600 yard range is mostly closed in from trees and a hill so only a small part at 500-600 gets a little bit of wind. you might have said this up top somewhere, but are you shooting cold-dirty barrel or do you clean after a day, or somewhere in the middle?
 
Yeah, In one of the videos, I out lined what im shooting,

The rifle is shot cold - dirty, pushing 900 rounds since it has been cleaned at all.
