Timberwolf; in certain cases an encore will not cock if the stock mounting bolt is too long, remove the bolt and add a thin washer. This may solve your issue
I believe so, not sure what rifle you are using but 150gr Volume, is generally considered the MAXIMUM amount. I would try 2 pellets and see how accurately it shoots. I imagine your shoulder will thank you.
I think your best bet sticking with pellets would be the White Hots. Seems like they get brought up the most. I quit shooting pellets years ago and haven't looked back, but that's for a different discussion
I have considered painting one of the crosshairs white for dark timber/ low light situations. Not sure which paint I would use, but you may be on to something with the Birchwood Casey
I think that pretty much covers it. I have read about some issues with SOME of the mrx. The truth is you could buy two Omegas for the price of one mrx.
Tc Omega, shooting BH209, leave loaded as long as there has been no moisture introduced. Solid, simple, affordable. (Not the BH209, certainly not affordable).
