Terminology for new guys

I have been lurking for the most part and some of the terms used here are a little unfamiliar to me. Bump, short chamber, etc. as an example.
Just wondering if there is a ( treatise ) or a good book to bring me up to date.

It has been about 30 yrs since my last reloading/smithing.

two great sources:
Mike Ratigan's book
and The Benchrest Shooting primer - precision shooting publication (also a great resource if you haven't subscribed before).

You can also do a search on the different boards here, and using key words you will most likely find your definitions.

I only have a vague idea of a short chamber, but I can tell you that "bumping" is referencing shoulder bumping and is used when, after a few firings, you brass becomes difficult to chamber (assuming this is NOT due to an over-pressure load). Your full length sizing die can be (very precisely) screwed down to push the shoulder down say .0005 to 0.001 to allow smooth chambering and extraction. There are bump dies which do not support the rest of the brass while sizing, and in general not recommended as they can create further case runout. Some shooters will bump after every firing, some will after 3-5 and some never use their brass long enough to get to that point (competition PPC shooters).

Hope this helps, and gets you started in the right direction.

Les,

You have done one thing right.:)

You have found one of the best sites on the internet to learn from. The best accuracy shooters in the world visit this site from time to time. These riflemen usually are free with what they know. There is much to be learned here.

Hello Les,

Welcome to the forum. Mike gave you a good description of 'Bump' (shoulder bump). I think it need be noted that this works well with custom dies or dies that match the chamber closely. Assuming minimum SAMMI chamber and die dimensions! Mike, I would guess assumes if you are into BR you have that already. You on the other hand after a 30 year hiatus may not be there just yet.

What Mike said is good stuff. I have read TBSP twice. And I got Ratigan's book a couple weeks ago.
And they are both great.
I am sorta new. Just starting Benchrest with a Capitol B.
Benchrest with a small b. 2 yrs shooting at my local club.
The info is free.
Call Sinclair for any questions and the books. Great people and they are all shooters.

Great people. :)
 
Glen Zediker has a book, Handloading for Competition, that is very detailed and complete. Because of the author's writing style, it can be hard to read. However, it is worth the effort. It's available from Sinclair and from Zediker:

Welcome Les,


One thing please if I may.

If you ask a question here about terminology please make it SPECIFIC. :)


Every now and then some guy comes on with "would someone please explain Precision Reloading??" or somesuch...... I mean where do you go with this???

You've done a wise thing asking for a book, but books will invariably spawn NEW questions, as they SHOULD. If you will take the time to ask specific questions then you will find this board to be an incredible resource.


If you ask stuff like "What's the bast Barrel for my Remmy?" or Which primer should I use for my 6X.284?" then you will probably be displeased with your responses. For good reason.


I mention this only because you DID ask a good question, I'm taking opportunity to put the word out for others ;)


In partial answer to your OP, if you hear the term "bump die" walk away. "Bump dies" made with your chambering reamer DO NOT WORK although you'll still find the occasional dinosaur promoting them.


To "short chamber" generally means to chamber your rifle so short that you must re-set or push back the shoulder on all of your brass before it will chamber. Factory brass WILL NOT FIT in a proper "short chamber".....

Hello to pineapple country. If you have a chance to go to a Benchrest shoot by all means go. I went to my first one last year and I met the nicest bunch of gentlemen I have ever been around. They will bend over backwards to give you information and these are the guys who know. They will even lend you their gun and coach you on shooting. To me "one picture is worth a thousand words". Go to a shoot an enjoy....
 
Glenn Newicks book, The Utimate in Rifle Accuracy" has a whole glossary on benchrest terminology in the back. A great description of "our language". And it's still cheaper than Rattigan's book I believe.
