New .300 RUM bullet weight

[win.308stealth]

Don't know if this should be posted in the reloading section , but here it goes.
I am getting a rifle built built on a Rem 700 with a McMillan A5 stock with a Krieger 30 in. 1-10 twist medium varmint contour barrel. Rifle will be used to shoot paper to 1k meters, and maybe used for long range hunting if I get good enough to shoot that distance.
Just wonderig what peoples thought on what bullet weight I should start loading for it.

I would start at the 208 AMAX, try the 210 and 230 Bergers. 225 OTM, and 240's as well

The 200gr Accubonds and Retumbo or H1000 is a match made in heaven for .300 RUMs. Start at around 91-92gr of Retumbo and work up to around 95gr until you find your barrels sweet spot. My .300 RUM shot .4's with the Accubonds. Might also try the 210gr VLD's. Shoot that barrel out (1200 rounds of you're very easy on it) and then rechamber it to a .338 Edge.

Rechamber to .338 Edge. Now your talking. My preferred choice for this build was the .338 Edge but I am getting this rifle in this rifle in a trade, and the gunsmith had a .308 barrel on hand. I have some 210 Bergerac on hand, so I will be trying those out over Retumbo.

New 210 grain Nosler Long Range Accubond BC in .7s expansion on game down to 1300fps.

The Berger 230's will be the ticket for your 10 twist.

 

[win.308stealth]

Do you know if the 230's will be ok for hunting? Let's say, whitetails and antelope?

 

[xXlojackXx]

230's are overkill by about 100gr's for antelope and whitetails. But id rather have too much KE than not enough!

If he's not going to shoot the heavies, there is no reason for the 10 twist.

In which case theres no reason to going with a RUM.

 

[win.308stealth]

I have a .260 Rem for antelope and whitetails, I just want to use the .300 for some long range shots. 600 plus meters.

My 300 RUM, 1:10 twist loves the 200 gr Barnes LRX for a hunting bullet.... elk hate it.

 

[lhouston78]

230 bergers had two 300 rum's that both shot in the .3 moa range, both were 18 lbs.
