There is an answer to all the questions you ask. All you have to do is become a member of the ASSRA and you will start receiving the Single Shot Journal. This is the official magazine published for all members of the American Single Shot Rifle Association and it is a very Hi-grade publication!. The magazine is full of adds for all types of supplies and information about our shoots then, there is the association library listing which has more information about shooting in ASSRA matches and History about the ASSRA than you can imagine.
So yes, everything is out there, all you need to do is, get your membership.

Here is a link to events;

Thanks for this information.

This is helpful to me, and I appreciate it.

I'm just wondering why, if were a society to preserve a shooting sport, then why are we not making every effort possible to let people know "How".

I'm not putting anyone down, or this Organization by any means.
I'm glad I was told about ASSRA, I'm glad to be here, I'm glad to be a supporting Member.

I'm just pointing this out from my perspective of wanting to learn, wanting to gather information as anyone that is new, we want to know, we want to learn.

Teach early, give information readily.

Don't make it where you need to wait for the publication to come out, or ask 20 questions, when it's clear that we came here, because we want to know.

I think at this point on a marketing level if nothing else, give them (Newbies "Everything they want to know.
But not by having to search for it, in areas we don't know where to look yet.

Guy's I think you're missing the point here.
It's not look this up, or that up, or go to this part of the forum or another.
Go to an event.

I appreciate what you're telling Me"

But I'm referring to anyone coming onto the home page
to be able to see what were about, how to get involved
without searching every aspect of the site, that still doesn't tell someone how to start off.
Or asking 20 questions in 45 different spots in the forum, and having no clue where to start asking, on what part of the forum.

I'm again just pointing out, "it would be nice to have a general over all introduction on how to become a supporting member and a shooter at any upcoming event.

So "Not" about me as an individual, but again for anyone new who stumbles upon this site.

Thanks Scott I would love to talk to someone about this, if possible.

The current issue has results from recent medium and long range shoots with the rifle each shooter used, the caliber, the barrel with twist and length, the load, the bullet, the lube, the cleaning method, etc. 10 Minutes of reading would answer almost all the questions you have been asking and would show you why there is no one easy set of answers to your questions. By the way, it will also show that few of the shooters are using rolling blocks;-) There is also a long article by a very good shooter about how he loads and tests. Join the ASSRA and ask to be sent this latest issue.
