All of the above was clearly speculation... so perhaps coincidental but not irrelevant.
Of course. It's simply just not relevant to this thread about the Anschutz Trainer, which has nothing to do with Running Boar rifles.
It is completely relevant given that the concepts of the running boar design will be evident, at least in theory, in the flared design of this rifle, regardless of the design intention and purpose.
But thanks for your diligent policing of what is and what is not relevant.
I apologize if I offended your sensibilities. My observations were not meant to cause peevishness or give you the feeling that I was policing anyone's comments or looking over your shoulder. I was only saying that the "running boar design" that the barrel's "flared" end is claimed to represent is not relevant here because the rifle is not a running boar rifle, the barrel is not designed as a running boar barrel, and that any similarities are not intended to give the impression that it is inspired by or is a representation of a running boar rifle/barrel. The characteristics loosely defined in post #13 are not unique to RB barrels. Indeed Anschutz bench rest rifles have "flared" muzzle areas that in no way are related to "spritely handling" of such rifles.
Glen (Grauhanen) is right about the swelling of the Anschutz barrel at the muzzle. The barrels on all the Anschutz match rifles are contoured this way, and on many, this swollen 4" or so at the muzzle is not grooved for front sights. You'll find this barrel contour on the older silhouette Anschutzes like the 54.18 as well, which are strictly scope-sighted. As I understand it, this is to impart some choke at the muzzle. I haven't encountered the term "rebound choke" before, but hoytcanon has captured the concept in his comments. When the rest of the barrel is turned down, this very slightly enlarges the bore from the chamber to the muzzle section, leaving it slightly tighter at the muzzle (where it has been turned down less). Bill Calfee, in a somewhat similar vein, has stated that he prefers straight barrels (no taper from receiver to muzzle) because he believes the taper results in slight enlargement towards the muzzle. This is also why you see reverse-taper barrels (like the Benchmark) on a lot of benchrest rigs--to instill slight choke through the length of the barrel.I'm curious how the flared muzzle produces a choke? When one follows the barrel making process -> Drill -> contour -> ream -> rifle -> lap, a bore with consistent dimensions is the product. Pending the lapping technique, a slight gradual tightening of the bore will be present from breech to muzzle, but no sudden, abrubt "choke" near the muzzle.
If any maker contours as a final step to make a "choke, I do not want their barrel as it is liable to have great inconsistencies through it's length.

It's hard to see this barrel swell--and choke effect--on the many Anschutz match rifles as in any way disadvantageous. These match rifles have excelled in international rimfire matches for decades....
very low .300's and mid to high .200's. These rifles are so accurate that the shooter is by far the limiting factor . These are not bench rest rifles . Anyone that thinks that the rifle is holding them back , is dreaming . Just my opinion .
I have an Anschutz MP R set up as a "tactical" trainer . The muzzle is flared and is grooved to accept a competition front sight . Even though my rifle is scoped , the added weight at the muzzle is a benefit as I believe it helps with barrel harmonics and reduces the tendency for vertical stringing . As a tactical trainer ( Mil reticle , mil turrets ) , the shooter can very quickly engage targets from 25 yards out well past 200 yards with extreme precision and is meant to be shot off a bipod . I believe the new rifle will accomplish this very nicely . My MP R shoots 5 shot groups at 50 yards off a bipod in the very low .300's and mid to high .200's . I suspect the new rifle will be similar . These rifles are so accurate that the shooter is by far the limiting factor . These are not bench rest rifles . Anyone that thinks that the rifle is holding them back , is dreaming . Just my opinion .
So... a non-benchrest rifle shoots .2's and .3's, but this physical accuracy limit of the equipment does not hold back a shooter? Couldn't the shooter be nailing .1's and .2's, if only their rifle was more accurate? Maybe I'm just dreaming![]()
