Like many guys, I have been loading the 30WCF for many years...
Early on I discovered the accuracy of Winchesters 748 powder. I have used it in many guns, three different single shot actions, Contender, H&R and Savage 219.
In the beginning I shot Speer and Hornady 170g FP/RN bullets. Shot a pile of deer with them. Then the Contender came along and the 30-30 was now a pistol round... I loaded a 130 SSP and a 125 Nosler BT with the same WW748 powder. In my H&R and Savage I have shot a couple deer with the 150g Nosler BT bullet. Later still the 160FTX was avalible to loaders form Hornady. I have two deer with this bullet and the same load I used in the 170g bullets. As a rule I prefer heavy for caliber bullets, so if I had to have one, it would be the 170g Hornady RN bullet.
Almost all these bullets have shot this same load very well. (the 130/125 and 150BT used more powder. )I will not post the load, because altho, its proven 100% safe in my firearms, it is a couple grains over posted maximums. If you research this powder you will see that thru the years the suggested maximums have come way down... If you go with this powder, PLEASE follow suggested loads listed in manuels, stopping when you get pressure signs, or the vel and accuracy suits your needs.
Good luck the 30-30 is a great caliber to load for for so many reasons!!
