Bedding Anschutz Silhouette Rifle

When a used Anschutz model 1803 silhouette rifle fell short of its target accuracy capability, it was time to check its history. The previous owner had purchased the new barreled action and done the final inletting on a machine-duplicated stock. The outside finish was acceptable, but inside inspection revealed smaller than normal surfaces for action-to-stock contact both at the front and rear guard screws, which were also insufficiently tight.

Try Pillar Bedding

What is pillar bedding? Total pillar bedding amounts to having both front and rear guard screws being able to cinch up the action onto a solid pillar of glass which surfaces on the stock's under side even with the wood, thus permitting the screw heads to tighten up against the glass. The Anschutz M-permits 1803 use of a 5/8" drill to open the front guard screw hole all the way through the stock. The glass epoxy mix you use for this adheres permanently to the wood, A new guard screw hole must be carefully drilled through your new glass pillar.

There is a room-limitation on the rear guard screw action bedding. This takes more care but can be worked out. Once the glass pillars or areas are in place and totally cure-hardened, the wood surrounding these pillars must be carefully scraped away eliminating action to wood contact in the bedding area so that no wood expansion or shrinkage can influence the guard screws' tension. Don't expect uniformity if you leave wood-to-action contacts.

Target Accuracy Required

Silhouette competition with the .22 rifle requires target accuracy, yet a 101/2 lb. weight limitation. The photo shows its sophisticated adjustable trigger. Its barrel, just behind the front sight enlargement station, is .872". Beeman's Feinwerkbau Ultra Olympic type .22 target rifle measures 859" at the corresponding point. That .013" is immaterial. Those three and four position rifles do have a more massive receiver and action size does influence accuracy, as the bench rest shooters have proven.

The silhouette rules have required certain concessions in order to meet the weight criteria. The barrel channel was deeply milled out, as was some of the under-the-receiver wood. While fitting this stock the previous owner repeatedly weighed the rifle as he worked. With the barrel channel and action skeletonized it was not necessary to remove wood from inside the butt stock. If using a heavier, more dense wood, this might be necessary.

After-work Accuracy Tests

Shooting this M-1803 Anschutz silhouette rifle over the bench for accuracy after weeks of tinkering, was gratifying. On quiet days I got almost .30 caliber jagged holes at 50 yards with quality match ammunition such as Eley 10-X and black box. RWS R-50 seemed to especially please this rifle. Grouping of all other standard velocity ammunitions tightened from previous performances. Winchester's Super Silhouette .22 L.R. ammo performed outstandingly with ample velocity to knock-down the silhouettes.

Glass-patch Bedding

In lieu of the total glass pillar bedding, a substitute glass patch bedding can often be used very beneficially. Part of the wood can be removed to a depth of perhaps 1/4" or more if the area allows, and replaced with glass. Brownell's ACRAGLAS[trade mark], ACRA-GLAS GEL [trade mark] or the ACRA-WELD[trade mark] kits will handle all types of epoxy-glass bedding and patching jobs. Don't forget the release agent. Otherwise you might end up with a nearly inseparable action and stock.

.243 Rockchuckers Still in Use

Our shop still occassionally fits a .243 RC barrel. This original .243 wildcat member was originally built on .257 Roberts cases, sized to 6mm and the Roberts case shoulder crushed in very slightly at the back of the neck base for a holding headspace to allow the case to fireform to the new sharper-shouldered, straighter-bodied wildcat.

Its a great cartridge. I used the two I'd built for myself for many years before any other factory 6mm's, 243's etc., were available. One remarkable feature was the fact that the sharp-shouldered cartridge case held stretching to an absolute minimum. I'm still using a few of the .257 Roberts cases that were first loaded in 1969. Present .243 Rockchuckers are built using the factory 6mm case, sharpshouldered and body-straightened.
