looking for load data for the 300 rem ultra mag and 130gr barnes

Dr. John · #1 03-12-2005, 05:23 PM

I am currently looking for load data for my 300 RUM and the Barnes triple X 130gr bullet. I currenly use H-1000 powder for all my ultra mag loads but am open to any new suggestions. thanks

I don't use an ultra mag, but looking at the nosler loading manual it states "We (Nosler) were suprised by the near bench-rest accuracy when using 4350 with lighter bullets". Well, there you go. I would try H4350 and H4831. What does the newest barnes manual show as the accuracy powders with 130 grain bullets?

Barnes says to use data for their normal boattails but you might be able to go a tad higher. In their load manual they actually show H1000 as a preferred accuracy powder and they list 97.0 as a start and 102.0 as a max. They also list RL25 at 98.0 start and 103.0 max. And lastly H4831 with a start of 87.0 and a max of 92.0. These are the preferred powders. That H1000 load is supposed to top out at 3701fps. The RL25 at 3860fps. and the H4831 load at 3693. Let us know how it works. I'm interested in seeing how it does in my 30-378!! I would say if you've worked with any 125's or seen data for the gun it would be pretty much interchangeable data escpecially if you start about midway between min and max loads. These are my opinions and your mileage may vary.

Why A 130 gr in such a big case?Is for a varmit shoot?

I currently shoot 190 & 220gr matchkings. I am just looking for the flattest possible shooter out to about 400 yards. the 130gr should do it and I could also use it for hunting anything up to whitetail if needed. I have always loved the ballistic tip, however the 125gr is not designed for anything except for varmint, especially at that speed.

How big are your whitetails? A big one around here is 175 lbs. I used the 125 grain Nosler BT out of a 300 RUM to hunt them this year. I shot one @ 450 yards and the bullet passed through easily. The deer only ran about 40 yards and fell over dead. I didn't get a chance to try them @ close range but I doubt if it would exit anywhere this side of 100 yards. It really shoudn't matter though. If you dump that much energy into a 150 lb deer I don't think there will be any tracking.

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.
