Not all firearms are created equal, and such is the case of the '99. A lot of the older guns do
have headspace issues and have to fire fairly mild to midrange rounds. In fact, I have a couple buddies that neck size only and use mild loads because of head space issues. The game they have taken don't know the difference. I do not own a chronograph, therefore speed is not a concern for me. Accuracy is.
Of all the firearms I own, I only load my .243 near top end, and still under max published loads. I have found that loads in midrange/upper midrange are far
more accurate in my guns and they don't beat the heck out of the gun or me. Not to mention with the cost of reloading supplies going up, I can "stretch" my dollar a bit more.
I will usually start my loads at 5 to 10% above minimum
published loads and increase charges by .2 grain(s) until I find the load that groups well and I stop. I shoot a lot of reformed military brass. Thicker casings equal higher pressures. This is my procedure with all my guns/calibers.
For my '99EG loads, I use IMR4895, Remington 9 1/2 primers and either 150 grain Speer Spire Points or Hornady Accubonds. Both with flat bases. Depending on the brass, I run 40 to 41 grains of powder. IMR4895, in my opinion is almost the perfect powder for the .300 Savage. With the mentioned charge(s), my cases are nearly full, and I have almost zero chance of over charging without a mess on my bench. This powder is used in many of the calibers I load with very good results.
My "go to" manual: Lyman's 47th edition, and I don't pay a lot of attention to the submitted loads of which there are thousands and thousands on the internet.
You've heard this before and for good reason. Start low and work up.
Good luck, be safe and have fun!
