What is thw rate of twist in your barrel? Years ago i read that the 10 twist 7mm bore was the only one capable of putting all bullet weights into the end of a juice can at 100yds. My 10 twist 7mms an ackley imp. and a IHSMA bear that out. All my loads retain the same point of impact. My 7/08 9 1/2 twist Remington varmint wont. 168 horniday match probably best bullet. 160 gr.Rcbs sil. probably best cast. I dont have a favorite powder. A 7/57 military mauser was my first centerfire and remains a favorite. I remember when $10 would buy a 93 short rifle and a box of Remington UMC amo. Still have some of the boxes.
