I have always thought that the 513-T was one of the most ignored, underated of the smallbore rifles.
IMHO, it is a very good smallbore rifle for the begining or club shooter, or someone like me too old to benefit from an Anschutz 1903, 1907 or whatever, and it has the benefit of being quite affordable.
Plus, since I do not compete I love them 6 round mags!
The rifle is far more accurate than I can shoot it as long as I stick to subsonic, target ammo.
I would not part with mine for three times what I paid for it last month.
