Since you are a 'greenhorn', (your words), you probably do not understand that what the vast majority, (98 percent), of shooters call a LV is in fact a legal NBRSA-IBS Sporter. Why, because, that 98 percent of Rifles are chambered in a caliber larger than .23, most being a 6PPC.
I would not worry about having a HV, 10.5 pound Rifle will shoot just as good, and if it is a Sporter, you can shoot it in all classes.
A good example of what I am talking about is at our first match this year. The format was 10-shot Unlimited and HV. Gene Bukys won both Grand aggs, and the Two Gun, using his Rail Gun in Unlimited and his 10.5 pound Sporter in the HV Class.
At the Nationals, we shoot the Sporter 100 on Wednesday Morning,and the LV 100 Tuesday afternoon. Typically, 99.5 percent of all shooters will just continue with the Sporter in the LV class.........jackie
