My son has the next step up from the Wolf. His basic Optima has the 26" barrel while yours has the 24. His gun does pretty well out to 200 yards using 100 grains of 777 2F and a 250 Shockwave bullet. The drop at that range is noticable but manageable with practice. If you go with Triple Sevens suggestion of 130gr of pellets it flatens out a bit better.

The only way to find out if the gun will perform at those ranges is to try it. Your results may differ from ours but you should be able to find something that will work. BTW, remember that at that distance the energy of the projectile may be getting near the lower limit for some large game.

Good luck and keep us posted.
