An appleseed sounds like a great thing, problem for me is incorrect equipment.
The closest thing I have is an older yugo K98 clone or the Mosin M44, neither with any optics.
Though I would be willing to try with either of those, as the last time I had the M44 out I was able to hit a 8.5x11 paper 6/9 at 100 yds off a bench. (old milsurp ammo).
I would love to learn better technique.
Our usual maxim is "we run what you brung". You bring whatever rifle you want and we'll teach you the techniques we know work.
The original premise to which we still hold is that we will teach you how to pick up any rack-grade rifle with surplus ammo and iron sights and hit a 4MOA target out to ~ 500 yards, aka the "Rifleman's quarter mile".
The course of fire is modeled on the M1 Garand with it's 8 rd. en-bloc clip.
There is also the posting about the $99.99 rifle... Cabela's or Dick's, I forget which, has for sale. IIRC, I think it's a Marlin 795.
If worst comes to worst, let us know and many of the instructors have a rifle available for loan; usually a 10/22 "Liberty Training Rifle"
Blessings,
