.300 Win Mag Loads

Just wondering what others are using for .300 Win Mag, especially in reloads. I am shooting a 180g Remington Core Lokt factory bullet but want to get a die for my Tika. Thanks in advance!

Re: .300 Win Mag Loads

Look no further than Reloader 22 for the powder. I'm using CCI LRM primers, 180 gr. Hornadys and 76.0 gr. RL-22. Accuracy is excellent and the velocity is just over 3000 fps 10' from the muzzle.

I believe that 75-77 grains of RL-22 is where most people end up but, as always, WORK UP LOADS CAREFULLY FOR YOUR RIFLE.

Re: .300 Win Mag Loads

I load 73 gr of IMR 4350 behind a 165 Hornady or Sierra boat tails in WW or RP cases. This is a stiff load so approach carefully. Have used this load for quite a few years in 3 different Model 700's with no excess pressure signs.

Re: .300 Win Mag Loads

I've been using a book max charge of IMR-4350 under a 180 gr. Speer Grand Slam for a good many years. Same load shoots 1 1/4" or less in 3 different rifles and stomps stuff, but good.

Re: .300 Win Mag Loads

That's a lot of slow burning powder for a standard primer....

Re: .300 Win Mag Loads

winchesterbob I was thinking this also when I was working up this load with H 1000. In hodgdon reloading manual that's the primer (LR) they used. I called Hodgdon and talled to a teck and was told they will work fine. I have no problems using LR primers.
