Howdy Cliff!  Welcome to the forum.

First off, you can go to the CMP website and register to get a Competition Number.  This is free and open to anyone.  They will also have a list of local CMP matches that you can attend.  Most are open and do not require you to be a member of the club (for instance, I shoot in a match every month at KRGC in Kalamazoo, MI; although I am not a member there).  When you select a match, call them and inquire.  Go here to get your CMP number:  (You need to Login to view media files and links) .  Also, you can shoot your sporter in most local matchs, although it will not count for CMP score.  You are correct in that you must have an "As-Issued" Krag to shoot at Camp Perry.  If you do attend, you are more than welcome to shoot with me and my friends -  Always room for more!

CMP matches are always shot at 200 yards (or 100 yards using a 200 yard SR-Simulated Range target).  Camp Perry is always 200 yards.  The course of fire is 5 rounds sight-in in any position; 10 rounds single load slow fire in the Prone position; 10 rounds Rapid Fire Prone from standing; and 10 rounds single load slow fire in the Off Hand (standing) position for a total of 35 rounds.  Vintage, Springfield, and Garand matches all use this course of fire.

Vintage matches are open to As-Issued Krags and 1917 Enfield, as well as any mechanically operated foreign rifles (Mosin-Nagant, Mauser, Arisaka, Swiss K31, British Enfield, etc.).  Springfield is for As-Issued 1903, 1903A1, and 1903A3 rifles.  Garand is for As-Issued Garand Rifles.  Also, this year the CMP is starting a Theodore Roosevelt Commemorative Match, which is open to Krags and early 1903s only (no 1903A1 or 1903A3).

Hope this all helps.  Oh, and I'm Paul... very pleased to meet you!

The best advice I can give you is to sight it in before hand.  The five-round sight in is helpful for variances like wind and heat and such... but if you're not hitting the target, five won't get you in the black.  Sight in for 200, but if you don't have a 200 yard range at your disposal, then sight in for 100, and if you shoot at 200, then you'll just have to move your elevation and sight with the five shots.

Also, make up some dummy rounds (10) and practice the rapid fire.  Loading the first five is no problem... but the reload with a Krag is challenging at best, and a downright nightmare at worst.  You will only have 80 seconds to get ten shots off! 

If you need anything else, please don't hesitate to ask.

There are also Cast Bullet Association matches in Puyallup and Vancouver, some of the fellows shoot Krags.
