Bullet for 7mm Ultra Mag

[kodiak338]

I purchased a 7mm Ultra Mag a couple years ago and started reloading for it. I use this gun for Deer and Antelope only. The best load I have come up with is a 150gr Swift Scirocco with 89.5 gr of H1000. This combo shoots .429 avg. groups at 100 yards. I took my Antelope last year at 445 yards, my longest shot to date. I found the Swift bullet works great but very expensive. I was thinking of going to a Hornady bonded bullet and was wondering if anybody has their reloading manual and could suggest the best bullet weight for the 7mm Ultra Mag. Thanks in advance Kodiak338.
