Agree. I have not shot Tac class, only LG/HG. One advantage I see for having this class is that guys just starting out can usually compete much quicker with something they might already have within these rules.
The forend rules generally prohibit larger than 2 1/2" stocks and sometimes a smaller part of the stock that is actually flat and has a radius of some sort. There is a performance difference compared to the flat 3" and wider stocks. Most of the time they also need to have a magazine attached.
For some of the "purists" I would remind them that this sport does not grow quickly, we are loosing too many good people every year, and it is expensive and time consuming. It is no less than one year, on average, to have a new LG or HG built and that is if you can find a Smith to do it. Yes they can buy something used by why should they possibly handicap themselves when investing so much in the first place?
We need to keep the ranks of shooters healthy. If they can bring their factory or PRS rigs in and compete with front rests, etc, then I say welcome.
I also know guys who started in Factory, then went to Tactical, and then LG.
