Working with a new 300 wm rifle. initial shots with factory ammo. 200 eldx 2- ten shot groups. Both similar, 5 touching the other 5 within 2 inches at 100 yds. Either cartridge or my technique. Need to test further.
This thread is helpful as I am in the process of planning a new rifle. Could start with model 70 wsm or a custom action. Trying to decide on 6.5, 7 or to 308 bullet firstly.

2) Have you shot anything beside the 150 Long range accu bond...
