Well, ill step in. Up front, I have not used Hawk bullets since they were in Lakewood CO and then, it was for a 405 Win and a 45-90. That said, if they are made the same way they were then, i wouldn't hesitate to use them again. The soft copper jackets and lead are perfect for older cartridges and mushroom beautifully. Ask what jacket thickness they recommend for the 303S and try some. I have a 303S and have thought that i would look at Hawk but it keeps getting pushed back on the list of priorities so i have just been content to shoot cast loads. If you go with them, i would love to hear about your experience.
