7mm wsm

so i am wanting to handload some rounds for the 7mmwsm win model 70 black shadow. i would like one specific load to work for mule deer and elk. what do you brianiac reloaders suggest? i'm thinkin a 150 ish grain bullet would be suffienct for both? i dont have a lot of money so the cheaper the better ( i cant afford barnes bullets). hoping something a little cheaper that will get the jobs done. i usually archery hunt but when i do out of state hunts id prefer the rifle. ive got pretty good odds of drawing a mule eder nm tag this year so thats my main focus. i'd mostly like to just stick to one load just for ease not a elk load and a seperate deer load. anyway i think you get what i am getting at so any help would be great just something strong enough to hold together for elk yet not sso well that it wont get good expansion on deer.
thanks in advance for any suggestions. im open for anything that would work on a budget thanks!

We all know it is the shot placement that matters most of all.
Good luck!
that 7mm wsm is a dang cool cartridge! easy to load for too!
Good luck, let us know what you end up with.
I just finished developping a load for my Savage
I use the 150 gr scirocco and 67 gr imr 7828 at 2.920" coal
Gives me 3145 fps average and .75" 5 shot groups
Forget rl17 for the 7mmwsm, although it's perfect for the other 2 wsm
It tops on pressure before getting to the min of 90% case capacity as predicted by quickload

Rl 25 gave good result too, with same accuracy and velocity close to 3100
I think it would great with heavier bullets.
i also haad great accuracy with h4350 but velocity was slow at around 2950 but extreme spread in the single digit.
Good luck!
