Re: predator rifle
Depending on what range you plan on shooting the 75 grain nosler varmint bullets are deadly accurate in my 243's and very fast and flat shooting. Out to 500 yards they do well. The wind jerks then around pretty good when the range gets long, recoil is insignificant. With a brake you could easily watch your hits. If you go heavier than the 75 I wouldn't bet on it. I shoot the 107 matchkings a good bit and recoil will take you off target much more than the 75's in a light rifle. If your shooting over 500 though you may have to go with the matchkings. They shoot extremely well at 1000 yard targets.
Predictions are difficult, especially when they involve the future
