Re: 300 Rum Sendero2 starting out loading info?

My 300 RUM CDL likes the 180 gr accubonds and ballistic tips seated over 96 gr. of Retumbo or the 180 gr. interbond seated over 95 gr retumbo. I got good groups and less velocity with rl22, but it cost more for no improvement ove the retumbo.

The foctory remington ammo with spire points is too hot for my rifle, but the federals with the moly tip shoot very well if I loose my ammo in transit.

This would be a good starting point for you. Also try RL25 and H1000. As others have said, the 200 gr AB would be a great bullet choice for the 300 RUM. This bullet will open up on deer size game both near and far.

Re: 300 Rum Sendero2 starting out loading info?

Yes sounds like a great starting point. Have you ever reloaded before? I'd probably start off around 92 grains and work my way up to the 97 grains area using a ladder method... anything above that people seem to have pressure issues. (even though a local guy loads all the RUM's around here with 98 or 99, I haven't seen the point virtually little gain for way increased pressue not a good trade off to me!)

Re: 300 Rum Sendero2 starting out loading info?

I would stock up on and try the following for 180 grain bullets.
IMR 7828
For 200's add
H1000, RamShot Magnum, RL-25 and Retumbo to the list

The 7828 is going to fly with those 180's. The other 3 powders are for when you done playing with super speed and move on up to the 200 grain Accubond. I fixing to try the Magnum in my 300Wby with the 200's. I'm currently doing pretty good with 7828 but I know there is more potential as it has no muzzle flash of any kind so I know the powder is all done before 26" is up. I will be watching over a 300RUM in a Sendero here shortly. It's got an appointment with Darrel Holland next week for a brake first though. This will keep this rifle fun to shoot for the kids.

I've been shooting only 180's so far in my older Sendero, but after reading your post I would like to try some 200gr. Accubonds using retumbo or IMR 7828. what powder charges are you guys using?

Re: 300 Rum Sendero2 starting out loading info?

I used 95g Retumbo with the 200g AB in a friends sendero and got 3225fps. I was using fed 215match, OAL was 3.660". Got 3/4 group at 200 yards, then I shot a 3.5" group at 525 yards with it. It is warm, so start a couple grains lower.
