300 WSM Powder

[GJ12]

63.7 grains of h4350 out of my tikka shoots well at 2950.

This is with 180 nosler ballistic tips. Forgot to put that on there.

 

[Sykes]

RL16 worked well in mine, but I was shooting the 152 hammer hunter, really fast

 

[buddtc]

64gr H4350 with 178gr ELDX.

What kind of velocity are you getting with that recipe?

 

[MountainSide]

H4350 and 175 LRX have worked well form me, and has been easy to find on the shelves, here in Alaska at least.

 

[Pwb199]

66 grains of H4350 gives me 3120 with 165 grain Tipped Game Kings. Lots of success, all the way out to 697 yards with this combo.

Awesome!

It's looking like 4350 is winning this opinion. If it works for you in Alaska, should do the trick here in Wyoming!

It worked on this moose two days ago…that and a couple 175 lrx

What kind of velocity are you getting with that recipe?

2920fps in a 20" proof barrel
my Christensen was getting 3015 with a 24" barrel.

 

[goathunter]

Curious if anyone has used both RL17 and RL16 in the 300 WSM and could speak to velocity and accuracy differences? This would be helpful to OP's original question

 

[hunting1]

I am a big fan of H4831 in mine. Great accuracy in all of my rifles and the extreme spread is single digits.

 

[wind gypsy]

H4350 or RL16. Neither will get you RL17 velocity but both will be more temp stable.

All the records are set with 4350....and that's what I use. fwiw.

At least before RL16 and RL23 came around.

 

[Longleaf]

I use superformance, 180AB @ 2930 20” bbl, loaded below max charge

 

[doverpack12]

I did some below zero velocity testing with my 200.20x Berger load. Factory tikka 24” barrel. Zeroed for Norma 180 Bondstrike.

H4350 with the 200.20x had a 7 fps velocity increase going from between 57-59 degrees in July (average of 3 range sessions) to -7 degrees. The change per degree is small enough across that temp range to call it zero change.

 

[OpenCountry]

Pretty much what I use with 180 accubonds. Think I'm getting 2950 or so out of my 20" proof.

What brass are you running?

 

[Rieckman]

What brass are you running?

Nosler

RL 16 with accubond 180 at 2950 in tikka factory

 

[Shadow Illude]

H4350 with 200.20x works well for me.

Ive only used RL 16 with good results with 180 accubonds at 2950. Curious about RL 17 tho… anybody have luck with RL 17?
