TexasMacCase Wall Uniformity Matters in a "Tight Chamber"
I though some of you may be interested in an article addressing a chambering issue I encountered in a Shiloh Sharps 40-65. The article was just published in the Dec. 2020 Edition of The Single Shot Exchange Magazine & can be accessed at
http://www.texas-mac.com/Case_...a_Tight_Chamber.html. After the article was published by the magazine I made an edit to the title & some additional edits to clarify my comments on the Shiloh Sharps chamber dimensions. The changes are included in the above link. BTW, the problem I ran into is not due to a problem with the Shiloh chamber and may “crop up” and any rifle with a “tight chamber”.

bpesteveThis is often the 'case' with older rifles in .40-65 - I've had several Marlin 1881s chambered in .40-60 Marlin (later co-opted by Winchester as the .40-65 WCF), and all of them required thinning the necks of modern brass in order to hold bullets large enough for the groove diameter. Brass back in the day was considerably thinner than modern made.

RJM.@Jax.FLWayne,
Absolutely great info, thanks
Your insights and generosity of your time to post same are appreciated.
I have two barrels with tight tolerance chambers.
CPA Stevens 44 1/2 / 38-55 and a 35-40 Maynard.
Dave at Pacific Tool and Die made the reamers to 'my specs'
I outside neck turn to .011 as well.
Your paper on 'tight Chambers' provided me with
some new info I had not considered.
Thanks again
Bob
