Finally got a load worked up for my new Sendero 7 RUM. Since i had loaded my limited supply of brass several times the primer pockets have started to get loose. I decided to order new brass to replace it but had problems finding any. I finally found some Remington brass at Natchez Shooters Supply but they wouldn't sell it to me because they supply retail stores in my state. I got a store in my area to order it for me. I went to pick it up today and they got Nosler Custom Brass by mistake. I've been wanting to try Nosler brass but couldn't justify the $2 per case. They knocked off some on the price so I decided to give it a try. Here's my question. My load is within .4 grains of maximum for my rifle. I'm loading 105 gr. of US869 under a Swift 150 gr. Scirocco II. I really don't want to put any more unnecessary rounds through this gun if I can avoid it. I've alteady got 250 rounds through the tube working up a good load. Should I load the new brass with my load or drop down on the powder charge and work back up. I think I know the answer but I wanted to get some opinions.
