NickP,
I posed this question in the Rifle Silhouette forum a couple of months back:
http://www.graybeardoutdoors.com/phpbb2/viewtopic.php?t=41721&highlight=I would give it a good read. I also have been given a lot of info from the guys who shoot the Air Rifle silhouette game competitively.
I wouldn't recommend a pump or a high powered springer. The pump is just too time consuming with the ultimate goal to become a better shot. On the other hand, the high power springers are best left for hunting purposes. The high power springers shred scopes, and have a recoil that is not beneficial to learning follow through. They are also way to powerful for shooting at 10 meters in your basement. :wink: Just ask someone who knows :roll:
Lawdog gives you good advice that if you are going to get a springer to plan on getting a side lever, under level type rifle. The break barrel's don't have the accuracy. In all reality, to get a gun that will shoot and help you succeed in smallbore silhouette you need to spend some money. The 100 dollar walmart special won't cut it. If you want the best get a compressed air rifle. No recoil and the most accuracte.
Remember that there are three types of airguns:
10 meter rifles (low velocity, used for competition)
hunting rifles (rifles that shoot at or over the 1000 fps)
everything else ( walmart stuff)
As far as guns that I would recommend:
Guns to get for practice and
Competition:Anschutz 2002 SSP (single stroke pnuematic)
Anschutz 2002 CA (compressed air)
FWB 601 SSP
Steyr LG100
Walther 300XGT
Guns I would get for Practice Alone
EL Gamo 126 (harder to find, super accurate possibly compete with it. It will shoot with the $1000 guns, but can be bought around $200-$300)
FWB300
Diana 75
Air Arms TX200
HW97
Air Arms S410
FX 2000
Tau 200
Beeman R7,R9
Chris Winstead the father of Cathy Winstead has been coaching juniors for silhouette shooting. This juniors cleaned house on Nationals this year. Rumor has it that they were training with Daisy air guns. These are the cheapest route you can go, and seem to be pretty dang good:
Daisy Legend 853 .177 Match Rifle
Daisy Avanti Elite 753 Competition Air Rifle
Daisy Avanti Valiant XS 40 Match Rifle
On top of the issue of buying the air rifle you are also compounded with the fact that you have to buy a decent airgun scope and good mounting system. Many of these airguns are not made for scopes and you have to buy specially made mounts for the rifle.
Keep in mind that most of these setups are going to be almost double what you have into that CZ. It may not be time for you to invest into the airguns yet.
I think that the cheapest way for you to get good at shooting silhouette is either to dry fire your rimfire silhouette rifle. Or shoot at the 50ft targets in your home or backyard. These can keep you busy during the winter months. Here is a link to them:
http://cc.usu.edu/~chunter/animals.pdfI also run an online league, for shooting silhouettes at the 50ft mark. If you are interested email me, for that matter if you get an airgun there is also online airgun silhouette leagues
NickP, where are you located? I imagine we can find somebody in your area that can show you some more of the ropes of airgun and smallbore silhouette shooting.
Sorry for such a long post, but this is not a easy fix/answer to your question. One shooter told me that "airguns are mechanical nightmares" when you compare them to a rimfire. Oh well, good luck and keep us informed on your decision. Also think about posting more questions in the Rifle silhouette forum, there are a lot of master class shooters posting in there.
