I sighted in yesterday at the range with some ammo I purchased from Double Tap. It is 270gr TSX.
Some considerations:
1. love it. Never owned a big bore. I enjoy shooting it.... for about 10 shots.

2. I am going to have to file down the inside edge on my bolt knob. It scraped the skin off my trigger finger just below the knuckle. lol.

3. 20 shots sitting down sighting in, even over a period of time, tends to not be as fun toward the end. lol.

4. It is more fun to shoot standing up.

I debated on what zero to use. I settled on 2 inches high at 100 yards for a 200 yard zero. I don't intend shooting that far, but like knowing that I can shoot to 250 pretty much level hold.
