.308 Ruger M77 Mk2 Stutzen.
Without going back into the 'Stutzen accuracy' thread, I wonder if some of you can help me out here? Rifle basic trigger fitted- simplicity itself and a big improvement.
I don't want to get into home loading and am trying various factory loads. Geco 170Gn seems OK, producing just better than 2" c to c at 100yds with a traditional hold ie prone, supported, with one hand gripping the fore end which seems to be he most effective grip.
I'm thinking I would like better, but I'm shooting at a 1" circle with a 6x42 fixed mag scope (I don't want anything else on this rifle) and with that set up there is also the potential for placement error. I do notice that the vertical error in the groups is minimal (zero to 3/4" depending on the group) but lateral spread is 2" to 2 1/2". What could be the cause of this? Worst with S&B 150gn SPCE rounds which were in a 2 1/2" straight horizontal line!
I'm waiting 3 mins between shots with the bolt open and 5 mins between gps to let the barrel cool- is that enough?
Any thoughts guys, especially from the Stutzen gurus (although that may not be relevant!). What could be causing the lateral spread?
Any other recommended factory ammo I could try?
p.s does anyone know how to take out the front sight bead? There is a little push down detente, but perhaps it needs a sharp tap forwards as well?
Thanks for any input.
