CGN Cold-Bore Challenge

Crashman said:
Just because a rifle can hit a little black dot on a first round cold bore shot when it is aimed and fired properly doesn't mean the shooter can it on command. Plus some rifles are not capable of this level of consistent accuracy, bad bedding, inconsistent/heavy trigger pull weight, unstable shooting rest…the list can go on for ever. This tested is meant to show how consistent your rifle will shoot on a day to day basis from a cold bore, the true test of a rifle and shooter's ability.

What I meant specifically (I should have worded it better) is what if any difference is there from the first few shots from a rifle to subsequent ones as long as the rifle is zeroed properly?

I realize anyone can mess up and pull a shot (I'm great at that) but discounting shooter induced error, I have not seen any difference whether my rifle is cold or not. Even temp has not made a difference at only 100 yards (further out yes).
 
Why not try F class shooting?

2 convertible sighters then you are on for score. Alot of sighters are converted. 5 ring is MOA, V bull is 1/2min. Various distances mean you must dial your scope often. Play from 300m to 1000yds

All of the fun and a ton of great shooting.

Wish'n i had me a digital camera, or, knew of how to use one of those newfangled 'beam me up scotty' type of hy-tec devices all you youngsters thumb away at on a regular basis.
Will have to lean on me younger CGN cohorts to snap us sum photos of our future (hopefully occasionally on gong) CCB's, to feed this thread.

Can say this though, Last time out three weeks ago, both Flattbed's Oberndorf '98 HB 308, and my 1913 CG Tradeex M38 arsenal re-barreled 6.5 Swede ... they each went 3 for 3 from CCB into .7 moa on gong at 950.There are pics of this admitted anomoly.
We cased 'em up right quick after that so we did ... 'n headed back to camp to celebrate fireside, till the wee small hours. lol!.

I think this would be a fun challenge just a couple of question, what type of front rest do you have to use and what type of shooting position prone or off a bench? I'm looking forward to trying this when I get home.

Not up to me to decide but I think this would be really neat challenge if it were from field positions only (ie:bipod + rear bag) Not fancy 50lb bench rest but either way I guess...
 
I will try this for sure!

Maybe a month ago our local range was having a precision / CQB shoot and I was late for the precision shoot. I plopped my rifle down (bipod and rear bag) and nailed 6 steel targets in a row at 300m from a cold bore. I'd say the target were 3MOA but still, there is a lot to be said about a rifle that is properly zeroed with a known load. Scopes with a zero stop help too.

Yup.
That, is not such an easy feat in the real world.
When ccb does occasionally connect that far out tho ... I do me a gatehouse .. :dancingbanana::dancingbanana::dancingbanana:, and then promptly recase the 'ol king 6.5. ;)

I fired a CCB 3 weeks ago at a 12 inch wide gong at 1530m with my .300 Lapua Magnum. Going off my ballistic kestrel it called for 15.1 mils of elevation. Released the shot and missed the right edge by no more than 1 inch. Dead center for elevation. Me and my spotter couldn't believe it. So close yet a complete miss :(

Pfft! 7" off on your wind call at 1530 meters. Better start praticing!
 
The black dot is 1" when printed. This seems like an easy challenge but it is not easy to be consistent on your first shots 5 different range trips. Can you get into position the same each time? Did you reset your scope properly? Is last nights burito not agreeing with you? It is amazing how hard it is to be consistent in your shooting.

It is also different hitting a 1 moa dot rather than shooting a 1 moa group. You can shoot a 1/2" group but if it is off centre it can throw a shot or two out of a 1" circle and with it being your first shots there is no pre-group adjustment time. Have you ever tried a dot drill?

I like the idea of limiting it to bipod and rear bag to keep it even.

If most are in agreement with that I will change the op.

I like it. Shooting a tight group is one thing...actually hitting what you are aiming at is another. Especially if using .1 Milrad clicks. It never lines up perfectly on your POA at 100m. I always find myself holding off a few mm or so.
 
I think of a bypod is a great idea and an even better one would be shooting it off of your back pack like you would do if you were in a real field position like the military would do if it came down to it I think it would give all these want to be sharp shooters and tactical guys a real idea what it's all about to do something like this in the real world not of a comfy bench and seat.it would be more interesting to if you had to do it with a factory rifle no customs or 16 pound rifles.

Just my 2cents that is

Ya I know right!
And there wasn't much more than a 5km\h wind from the 2 o'clock. That was using ammo i'd never even tried before. Just chronied a few the day before at 100m. Shot about .65MOA.
It was Lapua 220gr scenar L's from mister Peter Dobson!

Well our Military Sniper rifles are Custom and weigh at least 16lbs so you'll have to roll with that!
 
And then there are those of us who precision shoot for the pleasure of it. No competition...no "tacti-cool"...just the enjoyment of trying to better your skills and learning.

Me... in a nutshell.
 
693 .... I doubt that trying to "keep it even" is going to be easy. Advantages are likely to go to the heavy barrels with lower recoil and a smaller bullet diameter. If the challenge is to keep inside the dots, does it really matter how...

Thanks for elaborating on this, makes sense now. Bipod and rear bag is a good rule.
I shoot at those 1" SH targets all the time, the wife came out with me last time and shot a very nice opening group dead center (first shots out of the rifle that day). I showed her this thread and she wants to come out again.

I don't think it makes a big difference for 3 shots on rifle weight, barrel profile or bullet diameter that it will skew results. I think a mechanical bench rest removes alot of the shooter involvement from a good shot and since this is an accuracy challenge and not about small groups most modern bolt guns with good ammo can accomplish this with a good driver.

Since some clubs only allow bench shooting there is no reason to limit that out as there is no need to exclude anyone and I know I am less consistent off a bench than prone.

J996 - nice rifle and that is awesome that your wife shoots with you and shoots well.!

I am updating the op with the new rule.
