What if.... A remedy for the "cold shot".

Most long range shooters will agree the first shot at long range, or a "cold shot" say over 650-700 yards or even further can be less than accurate compared to the same shot two or three rounds later. At a target it's one thing, At a game animal it's a whole different matter. Complete misses or worse, a poor placement can occur. What if a guy had an answer for this? I have developed a prototype product that can eliminate this issue in the field and before I go through the layers of red tape in patenting it...what are folks thoughts on whether it would or could be marketable? How many out there would buy this? I'm about 90% ready, but researching patent laws, etc. I want to get a feel for if it's even worth the trouble.

I really don't believe such a device can be built but if it can you'd certainly have a big market for it.

There are lots of things that can be done to improve cold bore accuracy but nothing can totally eliminate changes that occur in the chamber and tube due to heat. Reduce them? Yes, eliminate them? No. Not until a new metal can be created that does not change dimensions with heating and which cannot be fouled.

Re: What if.... A remedy for the "cold shot".

I've been testing this device in the spring as of late. Early mornings with temps around 35-45 degrees. It's getting warmer now but I would set right up with the rifle staying locked in my winterized travel trailer overnight. I kept it in a cold environmment in a scabbard in the back of the truck while driving out of town. One morning I shoot at a 600 yd. Target, 4ft. By 4ft. Cardboard painted flor orange with a black circle 8" wide. Next morning I would return, device on and inside the barrell heating it (its really crude looking right now, but functionality is what matters right now.) Straight up one shot at the same target and compare. The previous day cold shot, lets just say its a good thing the target is as big as it is. The "heated shot" is much better, actually inside the blackened area most times. I have compared this scenario on 6 different cold mornings and the shot aided by the device is always better.
Granted, this is not a $5000.00 custom rifle, but an off the shelf browning A bolt with some trigger and bedding modifications and a personal load that has taken alot of research. That being that, I find this device to substantially increase the accuracy of that moment in the cold fall when a game animal isn't going to give you a few warm up shots. Lol.
The trick is to 1, heat the barrel evenly from the inside and all along the bore. 2, heat a slightly fouled barrel, not a spit shined clean one, and 3, the "device" cannot be made of metal itself as metal expantsionn would prevent easy removal at the moment of truth. So yes, the device must be removed prior to shooting, but at ranges that far, a little setup, ranging etc. Has to be done anyhow so one more step in your setup is not that big a deal.
But so far, this thing appears to make a difference!

There are THREE THINGS that make a huge difference!

1. Accurate zeros

2. Accurate Data Book

3. Accurate zeros at varying temps!!

too many variables for consistent first shot accuracy in my opinion. Great concept but what happens when you travel to hunt and have a springtime bear 700 yards away and it's 80 degrees on June 1st and you use the same rifle at -10 in WY for a giant mulie at 875 yards and the wind is blowing which reduces heat?

First.....how does "wind blowing ...reduces heat"? Ten below is ten below. 80 above is 80 above. Wind hase NOTHING to due with ANYTHING. Now, once the tube is heated up the wind aids in cooling the BBL, but that is a matter of convection.

As far as the OP...I don't have a problem with the first "cold bore" shot. I test my hunting zeros with cold bores..at least 1/2 hour between shots. And even if I didn't, if I had a bore that changed zero enough to matter due to heat I would convert it into a FF tube, a plinking tube, or a tomato stake.

Never take a clean gun into the field.....mine all have at least 10 shots down the tube before I hit the field.

Well you ARE WRONG. WIND BLOWING ON WARM METAL COOLS IT.
