I have had wonderful success with these Stevens rifles using quality barrels. Yes, I have shot a number of groups that would be considered screamers but that is with rifles that don't conform to any BR classes.

Nor shot under match conditions - which is how most BR shooters define true performance. So take it or leave it.... no matter.

Ok Jerry. That is a fair and well stated response. I thought I was going to get a "my gun does groups like that all day long" kind of response and I was preparing for the whiplash of my BS flag going up as fast as it could. But you admitted it was kind of a fluke type of happening and I can agree.
Find it
Range it
Click it
Pull it
Dump it

If it's not far, it's boring.

Len, it is all in the rifle set up. Once the load/rifle is proven to be accurate with no vertical or fliers, you just need to shoot and observe what it does relative to conditions.

A 'driveable' rig is easy to figure out. Easy to adjust for.

What I find with many situations is the rifle shoots a few smoking groups. That becomes the accepted norm. Go further and all the gremlins start to pop up dissappointing the shooter.

Been there - maybe write another article.

I am honest with what my rifle can and cannot do. Some barrels shoot. Others don't. Sometimes you need to go through a few pipes before you find one that is accurate. This is pipe Number 3 from this manufacturer but the first of the super match line. The other two were from a lesser grade and boy, did it show.

Sticking to a top line maker sure helps reduce the number of installs. But does not guarantee success as I am painfully finding out right now. $$$$$ Ouch.

Unless there is something grossly wrong during the shot, we have to count ALL shots. Especially, those flyers. Best 4 out of 5 doesn't cut it. It's that flyer that will definitely nip you in the field.

It's the average of your LARGEST groups that determines the accuracy of your rifle. Not your smallest

I can honestly say that this rifle is EASY to shoot as shown by the other shooters who did what I did and had never shot that rifle before. Lionel hit the sub MOA rock at 1 mile on his first shot - the BUM!. They trusted that whatever adjustment I told them to make, the rifle delivered.

Need 8" of windage, aim over 8", HIT. None of this a little high, a little low, a smidge left then right. Chasing the target around like it is a scared rabbit.

If the target is sized for the accuracy of the rifle, the bullets should land on target 100% of the time when you figure out what the conditions are doing - REGARDLESS OF DISTANCE (unless your bullet starts to tumble).

Otherwise, your accuracy is not what you had expected.

Pity you aren't closer, cause I would love to take you out and put you on a 1 mile rock.

It is way too much fun and you can watch your own trace right to the target. Big reason most of my boomers have been sold off. Just don't see the point for busting rocks.

Re: Shooting a 223 to a Mile Accurately By Jerry Teo

So is there something innately different about specific bullets and calibers that let them travel well subsonically? I ask out of curiousity because I have always heard they start to wobble if they are not supersonic. I know lost river filed a patent to increase the gyroscopic stability of their 408 round but your article seems to imply that other bullets exhibit this without the explicit goal of shooting a 223 to a mile. Would it be logical to think that with the proper setup that you could launch a 338 to 2 miles?

Re: Shooting a 223 to a Mile Accurately By Jerry Teo

As I said in my article, I am only refering to those with far more engineering skills and tools to monitor this situation. Their conclusion is that a bullet does not slam into anything when it goes subsonic and that spin stability as offered by the barrel INCREASES as the velocity decreases.

What does happen is the aerodynamic ballance of a bullet changes. This can make some bullet designs unstable. If that occurs, there is nothing you can do to change this.

So, the only way I know is to launch a bullet at the horizon and see what happens. If the bullet makes it subsonic by a comfy margin, it will stay stable until it hits the ground.

If you could dope the wind and have enough elevation, the 80gr Amax could go 2 miles!

A bullets limiting factor will be drag and angle of fire. At some point, aiming it higher makes it fall shorter. I think this happens above 43deg above level.

So all projectiles will have a physical limit to how far they can be shot on level ground relative to muzzle velocity.

A 300gr 338 can go 2 miles IF it stays stable. I have seen these bullets get to a mile very impressively and I think they are subsonic at that range. That would mean they can go much further if you have enough up.

I was shooting a 139gr 6.5mm Lapua Scenar no problem at 2400yds. Ran out of up to go further but have no doubt that going to 3000yds is plausible. You just need so much up that it becomes impractical.

Thanks for the reply, it's really an amazing article. I'm sure it's encouraged a lot of us to go out and experiment instead of taking conventional wisdom for granted.
