300 wsm powders, what’s good?

[hunting1]

I've been reloading for the 300wsm for close to 10 years now. only caliber I've owned.
H4350 has worked in all 3 of my 300wsm for 178gr eldx and 180gr nosler AB doing around 3000fps with a 24" barrel. My current custom 300wsm with a 20" barrel is doing 2950fps with 178gr eldx.
H4831sc also worked really good with 180gr nosler AB but was only going around 2890fps very accurate though.
H4831SC works good with190gr nosler ABLR doing 2865fps
H4831SC also worked good with 200gr eldx doing 2820fps if i remember correctly.
H100V was also another good powder for 190gr nosler AB and 200gr eldx

As said above I am using H4831sc with 180 AB for great accuracy , around 2850 so good enough for me.

I’ve had good luck with imr 4451 and Berger 185 vld. Testing it with the Berger 205 elites right now

I've used IMR 4350 and am using Hybrid 100V right now. I like both.

These are first ten with Staball

Of those you have on hand and using the 200gr AB, I’d say the RL23. I have never tried H1000 but seeing how well my 6.5SAUM does with it that mat work. All you can do is a ladder and see how the velocity and pressure does.

I’ve been messing with StaBALL 6.5 for a year now in my .300WSM Tikka T3. I am not getting the accuracy I expected from it either. I’m about to start testing RL-16 and H4350 in it real soon.

My 300WSM prefers H4350 but will shoot IMR 4350 well also. Out of your available powders you should have good luck with the RL16, the RL23 may also works well depending on your guns preference. I have found that H1000 is a bit slow and I have no experience with Ramshot.

I've had great luck with RL17

Anyone use rl26 with good results?

 

[BjornF16]

Been using IMR 4451 with 168 TTSX and H4831SC with 195 TMK with good results

 

[MHWASH]

Hopefully it will like H-4831, I just picked up 9#s for a screaming deal.

300 wsm, 200 grain pills, and h4831 go together like peas and carrots. Wont be the fastest and you might get pretty compressed but it should shoot well! My go to load for a while has been 4831sc behind a 200 eldx.

Yup RL26 is amazing in the 300wsm. I’m getting 2963ft/s shooting Berger 215’s using RL26.

That's the answer I was hoping for. Now if I could only find some berger 215s

26” but others here with a 24” aren’t far off.

I'm working on a load now with h4350 and cutting edge 165 mtu. Will let you know how it does.

Is this with a short action ,? Just curious as some with long action can seat further out

Yeah a short with the extended wyatt box

My new Tikka should be here next week along with some once fired brass. Everything else I have on hand including 200gr ABs, ELDx and Sierras.

The powders I have on hand are;
RL 23
RL 16
H1000
Ramshot Magnum
And just a touch of H4831 probably just enough for load developing.

I heard of people using H1000, but have yet to see load data.

H1000 is a really good powder for that.
