Hopefully I don't sound too preachy, but I love silhouette so here is my 2 cents.
To answer your questions: There are two categories: Hunter and Standard. Hunter is a rifle that weighs 8.5lbs or less with a trigger pull of 2lbs or more and the scope bottom? can't be more than 1.5" above the top of the receiver, and the barrel must taper. Standard rifle can be 10lbs 2oz with any weight of trigger pull as long as it's safe ie safety can be engaged and if you hit the buttstock hard it won't go off, scope can be 2" above the receiver, and any barrel including bull. A hunter rifle can be used in standard, so a lot of people these days like to use just one rifle for both.
I believe your Savage barrel doesn't taper so it would instantly be a standard rifle only hopefully your match directly will let you shoot hunter just for fun to get the xp
Also the cheek piece can't be above the center of the bore; yours might just barely be passing. Also I believe if you have an adjustable stock it must be taped over etc since you're not allowed to adjust it during a match i know, strange rules
...again local shouldn't really care. Keep in mind you can't have a buttstock that casts to the left or right or dips lower than the normal buttstock *ie you can can't slide an adjustable piece down.
For a 40rnd match
Hunter: B: 0-14 A: 15-19 AA: 20-25 AAA: 26-31 Master: 32-40
Standard: B: 0-14 A: 15-20 AA: 21-27 AAA: 28-33 Master: 34-40
If it was an official match and since it was your first unranked
you are now B class for standard, you are still unranked in Hunter. To get out of B you will need to shoot 3 A scores during the season, doesn't have to be in a row. If you shoot two above your class you BREAK OUT! so if you shot a AA score once as a B class, you instantly become A class. Great job shooting 10, yes that's great for your first time out! Silhouette is incredibly relaxing as it is challenging, 99% of it is in your head once you get the basic motions down.
Most people use 20x or 25x+ I highly recommend starting at a minimum of 10 or 12x and working your way up to 16x on your scope when you are comfortable. Never change your magnification based on shooting a different animal.
Some tips... hmmmm. Dry fire a lot! print out some targets ie 10m in your home and get 10m air rifle print outs. Work on your stance, don't overextend your body...do what is most stable FOR YOU ie some like to put their thumb on the bottom of the trigger guard others like to rest the trigger guard in their palm. Over time you will naturally know how to position your body so when you raise the rifle you aren't "searching" for your target. Work on natural point of aim...there is a great video on here that describes it that I will try to find later. Keep your front foot always planted, your rear leg moves either back and forward to adjust height or slightly move it left or right to better "rest" on the animal. Closing your eyes to find your natural point of aim for 5 seconds then looking helps to realize how to adjust.
STRUGL hit it spot on...one match is 40 matches! Don't let your last shot dictate your current shot...bad shots aren't worth remembering. Also, it's not fun being around negative shooters wither it be them being frustrated or telling you how bad they are doing because now you have that in your head. Silhouette community is great and people have a ton of fun! You will do your best shooting when you're not even thinking about it and having fun.
Great job on rams being your best, if you can find out what ammo groups best with your rifle at 100m or yards if that's what your club uses. Make sure to bring bags/rests every match and know your elevation for each animal and don't 2nd guess it during the match! You used a rest, it's correct. I second guess WAY to much and it gets in my head and it's down hill. Also when done with a animal change your elevation for the next animal before removing your gun from the line. Be careful, when you end up shooting both Hunter and Standard you usually shoot the same animal on the next relay depending on how your club runs things so you don't want to Shoot standard chickens, then when you shoot Hunter chickens you accidentally already set it to pigs.
Edit: Also never add up your totals until the very end! When you tell someone your scores just say whatever your got..."chickens, 1 and 3" Don't think or write down 4 on the side because then for pigs you will be like oh 2 and 2 another 4 that's a total of 8 and i have 2 animals left so I now need 7 more hits for an A score and it will get in your head, especially in the end. Just shoot your game one target at a time.
Some helpful tools to bring...bags/rest, a little timer I set mine for 2:45 and press play when they shout READY
You get 15 seconds between the ready and fire command and 2:30 to shoot. Always take your time on each shot, you have 30 seconds per shot. A small clipboard for your score card so it doesn't blow away and a pen...people will take your pen so keep it close! Having 2-3 mags preloaded takes some stress out. Bring a light snack that is easy to digest and plenty of water. A vest helps you with making sure you're place the rifle in the same spot every time...consistency is key in this sport!
I think that's about it....
Check out Erich Mietenkorte's youtube channel: He is one of the best shooters out there. If you ever encounter top shooter just know they are some of the friendliest people and to pick their brain.
Ridgway, PA is the holy grail for us. The Lapua Super Shoot is at the end of this month...it's like the endurance racing of silhouette. It might be intense, but you will learn A TON by shooting so much! Facebook is big on info for silhouette... there is Metallic Silhouette Shooters Society which is a private group and usually has the most announcements / updates. there is also Metallic Silhouette Shooting and also some lever action groups + more.
If you're on the boarder of WV near NOVA, send me a PM if you ever want to come out for a match!
Also, here are the most current rules.
