300WSM - 20in bbl.

Any one running a 300WSM with 20in bbl? What pills/powder did you settle on & what speed & performance are you getting?
Got a Weatherby WSM that came as 24in factory stock. Thinking I might chop to 22 or 20in. Would like to run 180 Bergers or 178 or 195 ELDMs.

My old Sako 300wsm was running a 19" barrel, I settled on 178gn eldm's and 2209....I'll dig out load details tomorrow if ya like ?

Absolutely 18-20” and that weight class never heard a better idea Superformance may be your friend their

Here's my old build thread and load development....18" and I think 2782fps with 178gn eldm's

Thanks Danny :thumbsup:

200Eld x @2740fps or more recently 168 Maker @ 3068
in mine Either shoots great and so does the Hornady 200gn ELDX Superperformance factory load

Lol, it's possible none of the answerers own those rifles now(or use them as their go to cannon) . A short barrel in the magnum category is 24 inches min, I've only been shooting forever and learnered a thing or two.

20" 178 eldm at around 2960fps Tikka and Hodgdon Superperformance

This 20" is still owned by the same guy as his long range rifle and has had it for around 6 years.
I load the same bullet and powder in 3 x 300wsm 2 x Tikka s and 1 Sako 1 20" and 2 x 22" they all are around 2950 to 2970fps

Ive had a 20" 300saum Sako A7 20" for at least 10 years. Its had a good wring out and I'm totally happy with it shooting the 168NBT doing 3.1k. Out to a long way for me. Wouldn't go back to a 24".

Yip I run a 20” 7saum 168s at 2930 175s at 2975 and 180s at 2930 I long for not a mm more barrel

Superformance is your friend with the 300WSM. My 20" Tikka shoots 178gr eldms at 3k. Around 2880 for the same bullet with 2209

Been using this set up for years.Shot hundreds of deer with it.
Tikka 20bbl 178gr eldx pill,RL17 powder,2960fps

My 1-10 twist shoots the 208 eldm fine

I was at 20” getting the same results as Monk, went shorter again to 18” and now shooting 168 AMAX and Re17. 2840fps Love it. Just use it for everything big or small.
