I have seen some marlins that are scary accurate..heck I drove myself nuts trying to get a tricked out 22 to shoot as accurate as my stock $90 marlin from k-mart!
That said... They are not silhouette rifles. I don't think you will find the triggers adequate and there are VERY limited number of shooters shooting them (I have yet to see one). The CZ for the same $ as you mentioned is another story all together. Tons of people shoot them. People have web sites selling mods for them (
www.452.com I think) very cheap. Triggers are easily adj and can be modified very easy. People can help you out with issuies like ammo preference and the like. Mutiple different rifle with drasticly different feels for NRA silhouette. Silhouette model is synthitic stocked very tapered bbl, Amer is wood stocked, little heaver than the silhouette model, the varmit is short but has a tapered "bull" bbl that is legal in both classes, and the lux, trainer, basic, style, etc. all in the $200-$300USD price range.
Both my silhouette SB rifles are Anschutz, I however started with a CZ and had NO problems finding a new shooter that was looking for a segway into our sport and snatched it up quickly. Not bashing marlin, but I doubt I would have been able to get my $300usd back out of it.
Hope this helps,
George
