New 300 win mag

[bates132]

I rescently ordered a Browning 300 win mag, and i am primarily going to shoot whitetail with it. I'm thinking im gonna stick with the 165's or possibly 180's in the accubond or possibly Siroccos. Any reccomendations? Load data? Thanks alot..

I run the 165 ABs with some H4831 in my 300 win and they do a number on Whitetails. I've stuck with the 165s because my 300 is a sporter weight rifle and not my long range rig. If you're going long, try the 180-200s.

I'd like to set it up for about 400yds and in. It's going
To be a 10lb rig, so I'm not concerned with recoil at all. If
I could find a flat shooting load with 180s that would be
Even better.

Try the 178gn A-Max ahead of 72.5gn of IMR 4831 and CCI 250 primer. This load printed .2995" in my rifle and trucks along at 3168fps. I haven't shot a whitetail with it yet. The last time I took it hunting a 80lb doe stepped out at 15 steps, I didn't have the heart!

Another good load; 180gn NBT/75.5gn RL22/CCI BR2. This prints sub 1/2" and cooks along at over 3100fps. This is book max but shows no excessive pressure signs in my rifle.

H4350 shot good in my rifle also. I tried the 165gn NBT. 72.0gn ran 3253fps and averaged .564". The 180gn BT averaged 3095fps and grouped in the .3's with 69.0gn's. I went up to 71.0gn with the 180 and velocity was 3154fps but groups went out to .7675".

Hope this helps. JohnnyK.
