    Hey everyone,
    I am reloading 30-30 ammo using Hornady FTX 160 Grain Bullets, IMR 8208 XBR Powder, & CCI 200 Primers.

    Here is my load...
    Case Trim Length-2.029"
    Powder Charge-29.3 Grains

    Here is the loads for the bullet on the 8th edition Hornady Book...

    Case Trim Length-2.029"
    Powder Charge-Min. 28.2 Grains & Max 30.6 Grains

    I have been reading forum's on over pressuring a round by seating the bullet too deep. I currently have 280 rounds of this reloaded to my specs and would hate to have to pull them and redo them.

    This is incorrect information. Seating deeper within normal ranges does not increase pressure in a bottle necked rifle round, straight walled pistol yes.. In fact it decreases pressure. There are plenty of articles on OAL and pressure with actual pressure tested data showing a decrease in pressure with shorted OAL.

    Here is a chart of real Pressure tested data from the Un. of Mich.

    Here is one from an old manual.

    And here are some comments by John Barsness (Mule Deer) a writer for Handloader mag.
