SIG_220 ,
Proving your point is meaningless.
All that matters is if YOU know you can hit what you want to with it
dependably with your set up.
Some arguments you can't win.
I think you know what I think.
The NRA rates the PTR-91 KP (short barreled folding stock variant)
OFFICIALLY as a 2 MOA rifle.
I do not know their official rating of the standard PTR-91 ,
but that same report stated that the expected the full length
rifles to shoot even better.
(I'm not sure if this is the report mentioned below)
Go to the JLD PTR homepage ,and click on their link to
one of their articles on the PTR.
This article is from the NRA, not JLD.
Also ,about the PTR barrels.
JLD purchased the equipment to make hammer forged barrels with the
special polygonal bore that was an extra for HK-91 imports.
After their first run ,they found the chambers didn't work well for
surplus military ammo.They tested it on Match and civilian ammo only.
As a result they started over and made their own barrel.
It has a different number of flutes,thicker demension ,
and it's my understanding it is NOT hammer forged.
I can't remember what the other method is called ,
button ground ?
At any rate ,it's generally considered more accurate.
Hammer forged process-length of steel with a hole in it is heated
and a center piece is inserted.The machinery hammers it to
the form,then the form is removed.
That's how HK's barrels are made.
Button ? (other method) -The riflings and complete bore are
ground/cut from a solid piece.
Both have their advantages ,but many believe the second method
produces more accurate barrels.
I'm sure someone will come along any minute to point out the
error of my ways.
It's the Arfcom way.
The gereal consensus among PTR owners,is the full length shoots
around 1.5 MOA ,and the Kurtz around 2 MOA.
A trigger job tends to improve this quite a bit for most.
I wouldn't care about what others think,your confidence in your own weapon
is far more important than what others think.
