.300 WSM WOW!

[6MMsteve]

seems like N555 would be a good powder for this case, just thinking don't even have a 300 wsm

I was lucky enough to get some RL23 recently and shot a coarse ladder test at 1K with 203gr Vapor Trail heavies

Sub 2 inch groups at 1k wow...!!

Did anyone tried N160 with 215gr in 300WSM?

 

[LVLAaron]

I'm about to try N560.

Shot some 200 hybrids with H4350. 2920FPS. I think 160 would work fine, according to quickload and GRT

 

[LVLAaron]

Where are the F-Class fellas running the 215's?

I've gathered
2800-2850
2900 +- a little
I've had some guys tell me 3000! (Absolute MOAB)

With RL23 I was able to push the 215s at 2920 and they definitely shoot up there. With 2213sc (H4831sc), the 220s seem happy around 2800-2820fps, considerably slower than the 215s but there's just no way I can see the 220s shooting near 2900fps without severely trashing your brass.

 

[antunRC]

With H4831SC, I'm shooting it around 2885-2910fps (215gr Berger)

 

[LVLAaron]

Cool. I've had some people reach out privately here and on facebook. Seems like 2900 give or take is a pretty common spot.

Is that a truck axle by chance? Very nice. How about the whole rig when it's ready?!?

I requested 300WSM / N555 load data from Berger and recieved several load for several bullets… it took awhile before I recieved the e-mail from them… yes.. I found it to work very well with 180GR. Ive found N555 works for 6.5 Creedmore, 22 Creedmore 7PRCW also..

 

[LVLAaron]

I've been told 555 is the right powder. Someone I trust said N560 that I'm going to try will work well, but it doesn't travel well to other ranges. Forum being slow and can't post a picture. Will try later.

BEHOLD: THE RIZZLER

The 300 wism can easily shoot over 2900 fps with the 215 Berger hybrids. The problem I have found is that is a "skinny" node and hard to stay in over 20 plus shots in a match.
There is another much wider "node" around 2850 fps that is just as accurate (in many barrels), easier to stay in 0ver a long string, and easier on the brass.
N555 works great....not sure about N560 or N565.

 

[Ranger188]

Do the 215's like to be jumped or jammed, how much?

What is a good starting point with N555, if you would please?

They are not finicky about jump or jam. Usually jump them from 20k off to 60k off

I started at 63g of N555 and got 2780 ish and worked up to 64.8 and got 2860 That's in a 30 inch barrel.

Both. .020 in and .015-.020 off are normalish. Theres bigger jumps too.
