Ruger Scout feed problem
The Ruger Scout is a push feed with a Mauser type extactor with a fixed blade ejector. A different duck, but it still quacks. This might be due to Ruger's choice for a single stack magazine..well more single stack than not, so a functionally siingle stack mag.
With this Ruger the heavy, wide extractor is supposed to grab the case rim on closing the bolt, so hand loading into the chamber is not a problem. The big extractor grabs a large section of rim for positive extraction. The standing blade ejector will roll the case out to your hand if the bolt is brought back slowly, but eject wide if the bolt is brought back smartly.
True Mauser controlled feed actions should not be hand fed to chamber, or so my papa's knuckle rap taught me. The hard steel of the extractor could chip or break. Some Rugers are controlled feed. The Scout is not. In fact, page 16 of the owner's manual provides instructions on how to load rounds singley into the chamber without a magazine. Check the instructions there and follow precisely. Safety first, during and last. If your copy of the manual is mislaid, Google Ruger Scout Manual for the PDF.
As to the feed problem mentioned, check carefully and closely for barrel or bore obstructions, dirt, grit, grease etc. Clean it well. Check for any dirt or metal filing between the extractor and the bolt face. Is the firing pin fully withdrawn into the bolt face? Check the ammo or snap cap you are using for damage or deformation. If using discount Russian or Chinese (shiver) ammo, try a major North American Brand.
Examine the feeding cycle carefully. Does the fresh cartridge slide cleanly and straight from the magazine, or does it run out at a slight sideways angle? Are the feed lips on the steel magazine bent? Even a little can cause a jam.
Is the rifle new, with you as being the first owner? Is it a second (or third..) hand rifle that may have been amateur modified..ie. damaged?
I apologise, but check to see if the ammunition is the proper calibre. I know, but you might be surprised at what I have seen sometimes.
If all else fails, contact Ruger's Canadian service depot. Find their contact on Ruger's web site in customer support. I have used them once with good result.
Please, do not attempt to repair or modify any part of the bolt and extractor assembly unless by a qualified gunsmith. If it is a new rifle, let Ruger take care of it.
I enjoy my Scout with no problems after 500 plus rounds. Some of this has been with the supplied metal magazine but most with the much better poly magazines.
Stay safe and I hope it works out.
