Cold Bore Challenge Q&A Thread

[Megalodon]

Just have some probably dumb qualifying questions. I've read the whole thread, but was following along as it went, so maybe don't remember.

Shots have to be taken after 8:00 MTN June 3rd? So I can't shoot the afternoon of June 1st or 2nd and post that June 3rd.

What qualifies as "practice?" Any shooting at all? So if I want to shoot the NRL Hunter match in UT June 16/17/18 I need to be complete with the CBC before that?

You can start shooting as early as you like on June 3rd and post the first shot that day after 8:00 am.

Practice is any rifle shooting, so you would need to complete the challenge before the match or start after the match.

Save it, print it, no remembering required

We decided to include a minimum range of 400 yards. That has been added to the official rules.

Cool, except the rules don't specifically answer my questions. That's why I called them clarifying questions. And acknowledged they were probably dumb because I could've guessed at the answers. Just wanted to make double sure.

Thanks for condensing the rules! Going to get out and practice some more this week

Ruhroh @KickinNDishin better dust her off!

Can I do 350 with a wood stocked 7-08?

Makes sense for the long range hunting subforum

 

[Lawnboi]

Might have found a 500 yard range. If I can get on I’ll be shoot the 3006

 

[Jimbee]

I have a 10" plate at 630ish yards and I can probably hit it if the wind isn't blowing.

 

[Brandon.miller.4]

Got some practice in last night, 1 cold bore at 610 inside the 10" circle then went to true at 795, 8 shots on a 12" plate. Excited for this challenge. That wind will get a guy on cold bore.

 

[BRTreedogs]

I hope it doesn't fill up and I miss out.
I work thru Monday.

Had my confidence destroyed and my ass absolutely kicked by the wind today. Missed a 10inch plate at 630 yds my first 12 attempts with a 6cm. Dirt flying all around the plate. Variable wind around 16mph at a 45ish degree angle.

Been there!

Ryan Lampers AKA StHealthy Hunter just committed to sponsoring the Cold Bore Challenge.

He is giving one lucky winner a StHealthy Glassing Pad and two Kit Sacks.

My current target layout. Probably hard to see targets but they seemed to be glowing this morning with the sun hitting them, white dots. Close to far is 370, 515, 670 and 907.

Didn’t fire a lot of rounds this morning but reaffirmed that calling wind does matter. My 907 target is an 18” plate with a 10” circle painted. Cold bore hit steel but not 10”, just out. Wind was light, 3 mph tops, left to right. Had to hold .6 mil for a center hit.

OK, I got out this morning for my first Cold Bore prep.

Equipment:
Christensen Arms Summit Ti in 270WSM
Swarovski Z5
Ammo is Unknown Munnitions, Bertrand Brass, 140 Berger Classic Hunter ontop of 63.5 gr R19 cooking at 3249fps on the chrono

The farthest I’ve ever killed a deer at is 450, so I was going to choose 500 MER (don’t want Sam breathing down my neck lol).

From the bench, I checked zero at 200 (my center hash) from last fall. Shoot sub-MOA at 1.75” for 3 shots but found I was about 3 clicks high at 200 so I adjusted.

Then moved to 500 and switched to 2-shot groups, first two groups from bench, then went to prone using my pack, and a rear bag, (same gear I’ll use for the official CBC) for the rest of the session.

But even in light winds (5-10 measured) this morning, and not cold bore, I was only 50% keeping in the 10” vital.

So I pulled up the target to 450 and put 3 out of 4 in over (2) 2-shot groups shot 20 minutes apart.
Noted that my group sized continued to shrink the more I shot.

My thoughts:

Like Cold Bow, the practice shots after a cold bore do make a difference, you get better, even if it’s slightly

I’m not ready for 500 MER. Need to do a few more true Cold Bore sessions at 450 and if I hit 100%, I’ll think about 500.

MIght have to wait for opening day of CBC to decide becuase if winds are high that even 450 isn’t doable, I’d need to pass that day. I can’t win anything so that doesn’t really matter, but a member would be in a pickle in the even the challenge is filling up. We deal with this in the Cold Bow on windy days and I’ve had to skip days as per the rules, you can’t shrink your MER due to wind so you gotta wait.

In all, super exctied to do this after this morning, although it showed in CBC fashion that it’s gonna be harder than many of us imagine.

Pics below. Top one is from last year at same range/same gun becuase I forgot to snap a pic this morning.




Here is the target. Tapes cover holes and are noted which group. Confusing but the more I shot the smaller my 2-shot groups got, and there are 3 different yadages on that target: 200, 500, 450. The black circle was added digitally as it was too hard to see my 10” ballpoint pen circle. Ignore the black dots and the muzzleloader hole in the 3” bull—recycled target

Even 400 is a long poke.

Was your 450yd deer one shot, or multiple?

1-shot. And then when I got down there, he tried to get up so I shot him a couple times a close range.

 

[mcr-85]

A general question for most folks here....Are you going to push your MER just passed what you have successfully killed animals at?

I have killed a bull at 748 and a buck at 710 (buck was the 2nd shot, I shot a touch over him the first shot) . I shot a lot more rounds back then. I don't know if I could make those shots now.
