The 7mm 154g Hornady Sp is one of the very best kept secrets in the reloading world. They are extremely accurate out of every 7 Mag that I have shot them in.
In the Browning A-Bolts, Win 70's, and Rem 700's, two loads are supurb on deer, elk, and hogs:
63.0g of IMR 4350, Rem Case,9 1/2 primer, bullet seated to touch
the lands at 3050-3100 fps
73.0g of R#25, Rem case; WLR-Mag primer; bullet seated to touch
the lands at 3200 fps
We have killed many elk with both of these loads. The 63.0g load will shoot a hole through both shoulders of a 250 lb hog.
The Interlock on the base of this flat base bullet really works as seen from the bullets that I have recovered.
