I have been fortunate enough to get to know Richard Graves pretty well over the last year or so. He has been an integral part in the success of my family of wildcat rounds, 257 Allen Mag, 6.5 Allen Mag, 270 Allen Mag and the soon to be released 7mm Allen Mag.
I was so impressed with his bullets that I asked if he would be willing to build bullets especially for the Allen Mags and since then we have been acheiving ballistic performance that is simply unheard of in all of these caliber families.
I use his bullets exclusively in these wildcats and the custom rifles
I build for them and have total confidence putting my name on a rifle shooting his bullets.
As far as the B.C. of his bullets, Richard does not have the time to ballistically test all the bullets he offers for sale. As such, he recommends that you test the bullets out of your rifle, in your conditions as this is the only true way to get accurate B.C. numbers.
I will tell you that they will produce higher B.C. values then nearly any other bullet in same weights offered by anyone else.
I have range tested the Wildcat Bullets used in my Allen Magnums extensively and will tell you that you will not be disappointed with the B.C. his bullets produce.
Are they magic bullets, no. But they are extreme quality, high B.C. bullets that generally shoot extremely well in most rifles.
I understand many Canadian BR shooters are getting excellent results with his bullets in matches already.
As Matt has correctly stated, Richard is taking a few weeks to get his fields seeded and ready for the growing season.
Send him an e-mail, generally he will respond very quickly but during this time of year he may be a bit slower in replying. Be patient, he is a wealth of knowledge and a great guy to talk and work with.
If his bullets did not shoot very well in your 6mm I would be suprised!
