They must be pretty decent, they seem to be sold out everywhere I've checked. May have to get a youth model if you're going to re-stock it anyways. I don't think youth models come in a heavy barrel though.
I have the 7XVH in .223. Shoots TINY HOLES. Best group so far was .226 for a 5 shot group. I quit at Turkey and Deer season last fall so dont know how good it will get.
My youngest gradson has the 7X Youth Model in .308. It has the tapered barrel. I worked up a load for my Rem 700 Heavy barrel for Deer Season that shot .397 with hunting loads. The same load only shot .600+ from the Youth Marlin. But again I quit because of deer season. The same load shot .700+ from my other grandsons Savage .308. Dont think its the guns, its the load. Both the Savage and Marlin shoot .500 and better with Rem Core-Loks. The accu-trigger adjusted down to about 2.4 on the .308. On the .223 it went down to 2.1.
