Informal Cold Bore Challenge

[YaakRiver]

Winter has finally settled in up here in Yaak, MT. In an effort to maintain/improve my shooting skills, I resolved to try to shoot as many days in 2026 as I possibly can, including a daily cold bore challenge.

I thought some other fellas would be interested in doing the same and keeping tabs on/encouraging each other. If you decide to participate, just know that there’s nothing to win - I have zero sponsors (owners). It’d be great if you include the rifle, ammo and filming setup, along with environmentals. Here’s a shot of my setup

- Rifle: Factory Tikka action and barrel chambered in .223; cerakoted, cut to 20” and threaded by Corey at Selkirk Mountain Arms. Factory trigger with Unknown Munitions trigger spring.
- Stock: KRG Echo
- Scope: Maven RS1.2 in Unknown Munitions rings
- Ammo: AAC 5.56x45 75 gr BTHP
- Bipod: Spartan Javelin
- Spotter: Kowa TSN-553 with a Wiser Precision Nighthawk on a SLIK 634 PRO CF
- Phone/Adadapter: iPhone with Kapture Gear

I started on Jan 1 so I’m 2 days in. Jan 1 shot was 473 yards, Temp was 20°, 2 mph 4 o’clock wind, 3140’ elevation. Today was 655 yards, Temp 30°, 3 o’clock 1 mph wind

Good call, I’ll bite.

I should be in - my new rifle should be in hand here next week - its my ability to film that worries me. I can film either the shooting or the target but not both. Private range right outside of my front door goes to ~700 yards so no worries there.

Cartridge?

Cartridge?

I’m shooting AAC 5.56x45 75 gr BTHP ammo but all cartridges are welcome.

No need to film both. This is just for practice and fun.

First round miss this afternoon. I held left in a swirling wind and to account for a touch of spindrift. Held center on the second and hit. I have a lot to learn about wind.

Did I completely read over that in the op? Lol

No sir. I corrected it thanks to your question! I should’ve mentioned that I’d do that in my response to you. Figured you wouldn’t be the only one to catch that mistake.

I’ll join in as well.

Impact was center left and low on the plate.

I can't video nor post pics ---- but I agree with this thread ----- Too many times people are concerned too much about groups.

1 shot, cold bore, get your heart rate way up, get on the gun and take the shot. Can you hit it? I'm talking the bottom of a soup or tuna can.

Very good post and thread YaakRiver.

I don’t hunt tuna cans very often, but my effective range on them from field positions would probably be 150 yds or less.

Also, does anyone have an anatomical drawing that shows the vitals on a tuna can?

I prefer my cans not have any vitals, I've already eaten the vitals (vittles) out of them.

from my limited experience as a kid, they're like bears, shoot center/center.
