I have the Heavy Sporter in 22-250 on my Axis that I use for shooting sage rats... It will put 5 in a nickel @ 100 yards. It does heat up and will move the POI a little bit... I also have a Varmint Contoured CBI on my 260... I feel that the heavy sporter is just as accurate as the Varmint contour... You just have to be more aware of how many rounds in a row you shoot.

When I'm in the PD field depending on temps... I just keep shooting as long as I have a target... I've shot 250 rounds in about 4 hours through it on occasion....

I always thought, that the Lite varmint and the Heavy sporter had the same contour....??? where/what is the difference in those 2 contours??
