I was in at cabelas and picked up a box of Browning labelled ammo - 2 3/4 inch 1 3/8 oz lead @1500 fps.
Browning ammo (according to the internet) is made by Winchester aka Olin.
It's pricey - 34.99 for a box of 25, but cheaper than similar products from Winchester (also 1 3/8 oz, but slower) or Kent FastLead ( 1 1/4 oz and slower).
If it really is what is labelled on the box, why can't the other manufacturers do this.
