Re: A bunch of simple questions.
Suggest you call and talk to Bruce Baer in PA about the 300 Wthby and some of the laminated hunting/LR stocks he makes. Think a Wthby or improved case would be ideal for what you want. Good quality and relatively inexpensive brass. Will not beat you to death with 14 lb gun but will easily reach well over 1000 with either 210s or 240 depending on throat. The weatherby case will shoot like a house a fire in minimum saami chamber. Last one I built is still shooting top notch scores and tight as heck groups. 1st Nationals it was shot in, shot 5.0" and 100 score. Nothing unusual just minimum saami and tight neck .336.
IBS Jr shooter of year Barak Robinson (11 yrs old)shoots 300 wthby and has shot several sub 4" groups to include a 3.1" perfect 50 with it.
