Hear Brian Pierce has some good 150 gr loads in the new Handloader Magazine,some using 7828....have not seen the article yet.

I used to use 58-58.5 H4831 for over 2900 from a 22" barrel,but have not loaded a 150 in the 270 since the 70's.



The 280 Remington is overbore.

The 7 Rem Mag is over bore.
