I have both of the rifles mentioned and was curious what you guys are using. Now I have a 4-12 Vortex with the BDC on the 22-250 and a 4-15 Nikon Buck whatever from Nikon on the 243. Read quite a bit, but there isn't anything that really stands out. I have had a Leupold recommended maybe with a 6-24 or something with a max of 24 power on the scope. Probably variable. Probably a 50 mm with a 30mm tube. 22 is a Rem Varmint and the 243 is a Stevens LA with a varmint aftermarket barrel. 22 is loaded with a 55 gr Vmax and the 243 probably a 105 Amax for now as i have a box to load.

Thanks in advance to all advice.
