Need help with new 300 ultra mag
I just bought a 300 ultra mag and I reload my own ammo. I would like some advice for some proven loads to start with. I am going to be shooting 180's out of it, only I don't know what bullets I am going use. I have shot seirra all my life in my other rifle's, but would like to try something differant with this new gun. I will be hunting black bear in Pa. and elk out west. I would be greatful for opinions on bullets and loads. Thanks, Tim

I shoot 180 gr Nosler Accubonds with 93 gr of H1000, seat bullet to just clear your magazine, should be in the 3.59-3.61 range. I got most of my info from Bigcountry or Stubblejumper, they are the guys on here to listen to. If I can be any help pm me Id be glad to help you out. One note, higher velocities in these guns (3500-3600) have been known to reduce barrel/throat life, I try to keep mine in the 3200-3400 range.

My Uncle is currently using 180gr Hornady Interbonds with his Ultra Mag.
Although (I think) all he has done is punched holes in paper so far,
he is very impressed with the overall accuracy from 100yrds outword towards 500yrds.He also says there is 100 bullets/box and the the price of them is lower compared to similar makes in different brands.

the AA 8700 will increase barrel life over the other powders.

Have you actually tested identical, barrels cut with identical reamers

Actually my point was that different reamers are made with different throat lengths which can have a great effect on throat erosion and therefore accurate barrel life.
