    So I recently came into a Savage 99 in .300 savage.

    I cut and formed 50 pieces of brass from old 308 brass. I have 200 150 grain Hornady 300sav canalure projectiles.

    I would like to use RL17 or RL15 as I have 5 pounds of each.

    Any insight on this! Thanks!

    1. I use Hornady's 150gr inter lock bullets in my savage 99 . Seem to get a fairly average of 1.25 " - 1.5" @ 100yds . That's with two different loads of either Varget or IMR 8208 XBR . I'm leaning toward 8208 but really not much difference between them . May someday try to work up better load but I'm happy with what I got . Savage 99 is a very good working lever action that probably was ahead of it time .
    2. I am using Hornady brass .

    Okay, awesome insight. I believe varget is relatively comparable to RL15. I’ll have to look for that load data.
    Thank you

    My 1950 procution 99 likes flat base bullets. I stumbled into a bunch of flat base 150 gr CoreLokts and it likes them with Varget. I used the same starting load as Sierra shows for the pro-hunter. I tried Game-Kings, Pro-Hunters and some old flat base Hornadys. It really likes the core-lokt factory load as well.

    I reload for a 300 and a 250-3000. For what it's worth I rented head space gauges just to be safe and they both checked out fine. For years I heard about head space problems with old 99 Savages, either I got lucky or it's not a big problem.

    Enjoy your 99!

    If you tell me which 150 gr Hornady bullets you have, I can run Quickload for you.

    Hornady has the following 150 gr bullets...

    BTSP
    SP
    Interbond
    GMX
    RN
    SST

    QL default MAX chamber pressure for the 300 Savage is just 52,939 psi

    Highlighted in bold is predicted MAX.

    102 % case fill
    43 gr Charge weight
    2,710 fps Velocity
    2,447 ft-lbs Energy
    51,080 PSI chamber pressure
    8,004 psi muzzle pressure
    95.6 % powder burned
    1.109 barrel time milliseconds
    ============================

    Just to add....

    Both Speer and Alliant show MAX 44 gr RL-15 with 165 grainers.

    Lyman 50th shows 42.5 gr RL-15 MAX with 150 grainers.

    So that's quite the discrepancy.

    Hence why we start lower and work up.

    RL-17 might be a tad slow (burning) for this combination,.. but QL thinks it should work, as the MAX predicted charge weight is not too heavily compressed, but slightly compressed nevertheless....

    Both Re-15, 17 are a tad slow for this bullet/cartridge/pressure combination. How funny it is when we realize that working with an older rifle and cartridge that one of the best powders is IMR-3031. I've worked on these loads for quite a few Savage 99s and the old standby powder works extremely well. The other powder to consider is VVN-135.

    My 300 savage, built on a Mauser, loved 3031. 4320 was only fair. You'll be hard pressed to get 47gns of RL17 in the case! Of your choices, RL15 is the most likely based on my experience.

    300 savage is an amazing cartridge. Superior to the 308 in my eyes for pure accuracy.

    3031 and 130gr Speer HP's work well in my brothers 99, 300 Savage. Barlow
