Re: looking for load data for the 300 rem ultra mag and 130gr barnes
this is not from experience, but, when I contacted Nosler for load data for the 125 BT, they told me that at the 300 RUM velocity the bullet would act more like a varmint load and just blow apart. If anyone has had good results with this bullet/cartridge combo I would definitely start load work ups. I have always had good luck with accuracy using the BT. and the price is right.
300 RUM and a 458 win mag...what more can a man want!
