is there any benefit to a barrel over 16" ?
No, just no, and I'm sure I've had to correct this misstatement before. Anschutz made the 1990s BR50 with the 2013 50cm barrel (19.7in not 18.5in), but at the time the round-action 1913 and 1907 rifles had standard 26in and 27.2in barrels. Current BR models are standard match barrels in BR stocks.Anschutz makes all their BR gins with a barrel length of 18 1/2" long for a reason. They found it to be the most accurate with match ammo.
With the exception of the longer sight radius the rest of this is just not true. I mean you may get a tiny bit faster velocity but not enough that would have any affect on the way it shoots.Longer sight radius, faster velocity, better-stabilized spin on the round as it exits the barrel.Tighter shot groups.is there any benefit to a barrel over 16" ?
What is it exactly that makes one brand of ammunition more accurate than another in a particular firearm?ammo, quality barrel & shooter means more in the end
Just thinking out loud here, but do you think you could buy, say a box of bulk cartridges, disassemble them into their component parts (primed case, powder, bullet) and then reassemble them after weighing and sizing the bullets into something with actual quality control?What is it exactly that makes one brand of ammunition more accurate than another in a particular firearm?
Wishful thinking?

In reality, ammo quality is what y'er chasing, not brand.
The best made cartridges with the tightest mv's, is what is necessary for consistent accuracy.
Not bantering for heated debate here, but I sure wish Bill would have gone into more detail over his above statement.A 16 inch, 22 rimfire barrel's accuracy, all else being equal, is totally dependent on the uniformity of the ammo.....since the peak pressure of the 22 long rifle cartridge occurs roughly at about this length.....
A 26 inch, 22 rimfire barrel, since the exit of the crown is several inches down stream from the peak pressure of the 22 long rifle cartridge, allows the quality of the barrel, itself, to play a role in the barrel's accuracy.

Bill Calfee, Quote.....There is absolutely no difference in the ultimate accuracy "potential" between a 16 inch barrel and a 26 inch barrel....
