Re: 270 Weatherby Question
150 HDY SPILs Flat Base, 71.5 grns R22, Weatherby Brass, Fed 215 GMM Primers. 3265fps at 12' and sub MOA at 200 yds.
Will flat out hammer Whitetails in the 150-230lb class.
Had descent results w/ the IMR 7828 powder but, groups weren't as tight and SD was much greater. Some really like 7828 in the 270 wby. I've had good luck w/ 7828 in the 7 wby.
And on Brass, Yep works like a charm. I just run the 7 wby brass through the 270 FL die and it chambers and shoots great.
If you try that load above start alittle below and work up, it's alittle warm in this rifle.
