0.8" average with 72 and 75 gr bullets
1.0" average with 100 gr bullets
1.2" average with 115 and 117 gr bullets.

Mine and another are on a surplus VZ24 actions.
Two others are on surplus Turkish Mauser actions.

One of the other guys is getting sub moa with the heavy bullets and not so good with the light bullets.

I don't know why, but I have noticed the heavy bullets group an inch to the left of the light bullet groups.
My rifle is also built on a VZ24 action, they are one of the nicest and strongest of all the military actions available, I replaced the original bottom metal with an aftermarket one with a dropped floor plate and a magazine length of 3.400". It also has an aftermarket trigger and safety, 3 position Model 70 style.

I like the M70 safeties.
I heard of a man stationed in Iraq who's daughter wanted a rifle, so I spent two months and built her a 243 on a Mauser auction. I sent emails with pics every night, it kept me away from the TV at night in May and June 2007. I had a great time, but I slit sawed and milled and drilled and ground until I got a $20 Chapman M70 type safety to fit. Never more, it is $30 Wisner M70 type safeties for me from now on. That extra $10 will mean allot more TV time for me.

I like VZ24s.
BIG5 had 1903 and 1938 Turks on sale often enough in 1999, 2000, 2001 for $50 + $4 WA state sales tax = $54 out the door.
I bought allot of those.
Then BIG5 in 2001 and 2002 had VZ24s on sale for $70 + $6 WA state sales tax = $76 out the door.
I bought allot of those.
Now 2008 Century sometimes has VZ24s on sale for $115 + shipping + FFL.
I have not bought any yet.

I killed 3 deer this year with 130 gr 270 at 400, 400, and 500 yards with Nosler Ballistic tip bullets.

Next year I want to use the 257RAI.
It is every bit as flat shooting, and might make a little less meat damage.

My .257 Ackley Improved is built on a pre-64 Win M70 action and a Douglas Premium barrel. It loves 50 grs. IMR4350 and 100 gr. Nosler Partitions. Typical 3 shot groups at 100 yards measure 1/2" - 3/4". This is an excellent whitetail and antelope load.
