How does the overall case length of the bullet affect performance? I am loading .117 gr Sierra's with 52gr H4831 to a length of 3.321 (max 3.325). If I seat the bullet deeper or shallower, what am I gaining? Yes, I am still working on loads and am new to reloading. I also have some .75 gr varmint HP's that I am told will flat out smoke a coyote. Should I keep the OAL the same? I am very confused here and I have read to my brain is mush. Any advice is appreciated. Thanks.
