Re: Data for ALL Cals Ackley Imp

27.5 gr of Benchmark, CCI 450 primer, RP case, 50/52/55 gr bullets at 0.020" off the lands - provides 3550 with nekid bullets out of a factory Remington 26" varmint barrel.

I did not provide OAL or COAL because it will be different for every rifle.

Re: Data for ALL Cals Ackley Imp

Jan 2000 I buy Keunhausen's scatter brained book on Mausers.
Feb 2000 I buy a VZ24 surplus rifle from BIG5 for $70.
Mar 2002 I buy a Lothar Walther .257 light varmint barrel $145

I get .257 Roberts Ackley Improved reamer from Dave Manson.
I build an action wrench.
I build a barrel vise.
I make an action truing mandrel.
I make a lug truing cartridge.
I make an inner C ring lapping tool.
I do a trigger job on the military trigger to control take up, force, and overtravel. Pull is down to 1 pound.
The bolt is bent with an Acetylene torch and sledge hammer.
I buy a Wheeler Eng drill and tap fixture and drill and tap.
Weaver #45 and #46 steel mounts are glass bedded to the receiver.
The barrel is dialed in on both ends of the lathe to within .0001".
Threads and chamber are cut.
The chamber measures still concentric on the lathe to with in .0010".
Stock is sporterized and glass bedded to the barrelled action.
A 40X Leupold scope is installed.
Barrel is cleaned and burnished with moly bore cream.
Winchester Brass is fire formed with 10 gr pistol powder and back filled with Cream of Wheat.
Case mouths are chamfered inside and out.
Forster dies are used on a Rockchucker.
Bullets are 75 gr Vmax moly coated for me by Russ Hayden.
Powder is surplus bulk military pull down IMR4895 that act more like H322.
Bullets are seated long to jam into the lands.

Late 2002:
1) 48.3 gr. gives 3757 fps and the extractor groove grows .0005"

2) 47.2 gr. gives 3736 fps and no extractor groove growth

3) 45 gr. gives 3674, 3621, 3630, 3614, and 3630 fps


A) All 5 shot 100m groups over last 6 years with 75 and 72 gr bullets average .87".

Can consistently shoot less that .5" when there is no wind at all.


B) With Hornady 100 gr soft point blem bullets, and 8.5x25x50 Mark IV scope, groups are less than 1" with 42 gr surplus bulk IMR4895 3220 fps

CCI BR4
64gr R-22
139gr SST

This load shoots to about an inch at 200 yards. It is pretty hot as the Nosler manual says it yields 3290 ft/s. I get a little cratering on the primers when the brass is a little older and neck tension goes up, so work up to it in your rifle.

Super Duece (222 Magnum AI)

27" 1:8 twist Shilen stainless select match, 204 Ruger brass necked up/previously fireformed, and 80 gr Amax at 3100 did rather well at 1100 yards today. Shooter who was rookie to this rifle had no problems with five consecutive hits on steel.
