I’ll be using a hunting rifle which is fairly heavy, over 25-30lbs. I’m undecided which stock to purchase, 50cal LBR or Tooley MBR stock. (It may not work for sporter stocks) Do you recommend adding two grooves at the bottom of the forearm and sitting on the guide rail? Is it better for the rifle to slide? What about the soft bags that will hold the rifle and has a lot of friction under it? Will it affect accuracy due to uneven friction? I noticed DC added 2 grooves under the stock. Please share your experiences with the guide rail.
