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

That's interesting and goes to show how different two rifles with the same chambering can be. I've got a .300 WM with a tight chambered 26" Lilja barrel. I hesitate going past 75 grs. of RL22 with a 165 gr. bullet. When I first started loading for it I used a published max of 78 grs with a 168 gr. TSX andwas getting velocities just shy of 3400 fps and hard bolt lift to go with it. So far I haven't tried RL22 with a 180 gr. bullet, but if I did I probably couldn't go past 72-73 grs. in my rifle.

.300 Win. mag.
Load that has worked well for me in more than (1) factory .300 Win. Mag. rifle is 76.0 gr. RL22 Fed. 215 primer in a Winchester brass case (not nickel) using a Nosler 180 gr. Partition. RL22 can vary lot-to-lot and I would start at 72.0 gr. and work up. Some people I know have exceeded 76.0 gr. with certain lots of RL22 but you will only know by trial and error and using it in your particular rifle. My success was tight groups and over 3,000 fps in a 26" barreled Browning A-Bolt & a 24" barreled Remington 700. Both rifles shot under 1 MOA & the Remington was closer to 1/2 MOA consistently. I've also used the same load using Norma MRP when I could find it.
