Im having a rifle built with a Manners T4 stock and will be using it in 600 yd BR comps at our local range. Question is, who would use a Bi-Pod with a rabbit ear bag or a BR rest like a Bald eagle "Slingshot", which I have? Would also like to get into F-Class shooting at the Lodi range next year, now there Id like to use the Bi-pod only with rear bag.
