Rifle Scopes-Selection, Mounting & Sighting In

Posted by on October 6, 2011

I have published a new book entitled “Rifle Scopes-Selection, Mounting & Sighting In.”    As an ex gunsmith, I saw a lot of badly chosen and badly fitted scopes.  Some seemed more suitable for artillery pieces than dainty little sporters.   Some were so big that they cleared the barrel only with the highest rings, and even then some lens caps fouled the metallic sight.

I saw every imaginable example of poor fitting.   Holes drilled and tapped out of line, badly fitted bases, whether mismatched, skew or out of position in some way or other, one base higher than the other, and even the wrong bases for the rifle.   If they had been occasional examples it might not be so bad, but it was not unusual, as I saw such faults often.

But even when the bases are the right ones for the rifle, and are properly fitted, manufacturing tolerances in rifles and mounts guarantee that the rings will always be out of alignment until they are lapped.   Of the many I have fitted, I have not found a pair that was not out to some extent.   The amount is usually too small to see, but one or two thousandths is all it takes to allow scope slippage, because the rings don’t grip the scope securely.    I have seen the finish scraped off by the sharp edges of the rings, and scopes dented by over-tightening misaligned rings.

The good news is that scopes can be properly fitted by rifle owners.   This book, and others I have written and plan to write, is characterised by the sort of detail missing from most published work, and is aimed at the independent, self reliant, hands-on guys who like to do things themselves, and do them well.

It is not a big book at 82 pages, but with 29000 words and 92 illustrations, it is packed with “how to” detail.   It explains the effects of size and magnification, field of view, the importance of exit pupil, how to fit various base and ring types, precision lapping for perfect alignment, workshop sighting-in, range sighting-in, and the point blank principle with trajectory charts.   Also, for added interest, how to tilt a scope to extend its range.   

It is a E book, available direct from me, boothroyd@polka.co.za, and will be sent by e mail.   I will gladly send sample pages to those who want to see the quality of content before buying.

Price is $25.   Payment will be credit card via www.gunownerssa.org.   Payment instructions will be sent with the book.
