A new cartridge (for me anyway) to load; the 300 RUM. The proud owner would like to start with Barnes 180 gr. MRX's & 165 gr. TSX's.

Any suggestions would be welcome, suitable powders, best bullets, expereinces & potential watch-outs (like Sissy-Bags for the Bench).

It's a Remington action in a McMillan stock with a 28" barrel made up into a Fly-Weight Sporter! Whew!

lets see pics

ewww, that's going to hurt. You have fun now, ya hear.

I have not done intensive tests with my 300 RUM, 28" bbl b/c the first bullet I tried was a gem.

Re25 under a 200 AB, Remington or Federal brass, WLRM or Fed215 primer.

However, I can assure you that H1000, WC872, and Retumbo are definitely powders to try.

the only suggestion
i can even think of is to cut the case in half
and neck down to 308.

And have a turd?

If it is a new rifle as well as being new to you I would not use Barnes bullets for the break-in period.....the softer copper won't smooth the barrel as well.

I second the 200g Accubond suggestion...

Cheers,

Dan

I use Remington brass, Winchester
Mag primers, 96.5gr of Retumbo, 180gr Accubonds. It has plenty of punch. Seating depth is what the magazine will accept.

I's a great cartridge Gerry..........the best of the 300 magnums............

With 168 TSX Match my rifle liked 94

of RE-25 and shot.3

It also liked H1000, 96 grains shot into .6 with the 168 Nosler CC

My rifle seems to prefer the 200's over the 180's ; 88 of Re-25 and the 200 Swift is a cracker as is the 200 Lapua Naturalis and 93 of N570......shoots beautifully.

With the 200's a brake helps

Hey Guys,

Thanks to everyone for the advice so far.

It's not my rifle so I'll have to ask if I can take some photos & post them.

It is a VERY nice looking, VERY light rifle. When my Buddy handed it to me the first time I thought I was handling a rimfire or .22 Hornet - it's that light. I'm begining to think I'd rather be the Gun Bearer here than the load testing Guy!

I have the Dies, his once-fired Federal cases (actually they look like minature Vases) and we're pondering the "How do we get this project going issue" as he's tired of paying @ $130.00 for a box of 20 Federal cartridges here in The Fatherland.

I'm concerning myself with two issue at the moment; the powder and how many sand bags I can get between my shoulder and Buttstock.

Gerry,

Fill a sissy bag with # 6 lead shot; that will take the bite out of the bitch for you

Blair,

Thx Pal.

I've already got three bags of various sizes made out of old Blue Jeans legs (w/ Glad Bag inserts) that I filled compliments of a local Golf Course with very clean, nice, white sand.

Used one of them on a friends Blaser R93 (very light) .416 Remington with great satisfaction but if your prediction si true I've got 200 lbs. of shot in the basement if #6 is required.

Gerry,

Welcome mate
