Loads for 300 win mag

I just purchased a Savage 116 300 win mag and was curious if anyone could share with me their "pet loads" with 180 gr. bullets.

I havent loaded any 180gr bullets for my 300 mag. My main load is 165grnosler accubond with 77grs of RL22 with mangums primers for deer hunting.

Best load I've worked up:

Winchester Case
70.0 gr IMR 4831
180 Grain Nosler Accubond or Ballistic Tip
Fed 215 Primer
3.332 OAL

This produced consistent sub MOA groups out of a Winchester Model 70 Classic. Best three shot group I've shot at 100 yards is .424".

Another load I like that gives consistent MOA performance:

Winchester Case
71.5 Gr Reloader 22
180 Grain Nosler Accubond or Ballistic Tip
Fed 215 Primer
3.332 OAL

I am still amazed how how much perfermance you can get with a 300win mag. I like 77-78gr of RL22 with 180gr bullistic tips, and getting darn close to 3100fps. And thats with a 24" barrel

When I had one a while back, I believe I was loading 72 gr of IMR4350 under a Sierra 180 gr Game King.

I have never used reloader 22 or any Alliant powder. I will try some.

This loadis from theold IMR reloading guide: It isa maximum load.

ARemington 180 grain Core-Lokt bullet:
A Winchester case:
A Winchester magnum primer:
75.5 grains (compressed) of IMR 4831:

That load makes sub moa groups when fired from the 28" barrel of my Mathieu. It also groups well when fired from my Ruger 77.

I may have to buy some factory ammo for now. I cannot find any magnum primers.
