I've got the 300 WM dialed in

[Osprey78]

I took a drive to the range today and was pleasantly surprised.



I'm using 70.5 gr of H4831SC under a 200 gr PT, with CCI 250's and Winchester Brass. I have to it magazine length and was using a bullet comparator.

Interestingly enough, the group measured (when I got home, sorry no pic) at 1.019"

I am not including the very top shot in that group for the simple fact that it was my first shot and something I found interesting was that it was actually at 2.885" where the other 4 are 2.889",2.888", 2.889" and 2.887" (all measured to the Ogive). I remember early last year messing with lengths and such with the comparator and noticing that it doesn't take much for a bullet to stray if it is not within the measurement range of the majority of bullets in that string.

There are 5 shots in total. The top of the triangle group if you will, has 2 shots inside.

I haven't chronoed this load yet, but the book shows it at 2910 fps. I feel pretty confident this will perform when put to the test this hunting season.

That is, indeed, promising. Good show.

Good shooting. Keep working with the COL and you should be golden soon.

I believe you are well on your way to a very good load. The OAL will come and then it will tighten up nicely.
Thank you for the post and photos.

Blessings,

I use that exact load. I think Nosler nailed it in their latest manual (which lists that as most accurate). It does great in my Ruger M77. I have to load to 3.340" due to magazine, but it does awesome!

Looks like you have an awesome load there.. I stick to the 30-06 with 180gr Noslers.. Thanks for the tip on checking base to ogive for consistency. I sill start using a sharpie pen on the case to identify any variances from a norm to see if that helps tighten up my groups.

Nice...I love those Nosler Targets

Yeah, they are quite visible down range.

Have you used the chronograph on yours? Just curious if it is getting near the book velocities.

 

[NWBlacktail]

No, I have a bad habbet of shooting my chrono's (gone through 2 so far ). I just got a new one, but haven't measured this load.

Hahaha! You just reminded me of this jerk that belongs to our Rod and Gun club. He is the local know-it-all, who likes to force his "knowledge" on everyone else.

He borrowed a friends chrony, and shot off on of the support arms. He has yet to even attempt to pay for the part.

Well, if you get it chrono'ed before I can, let me know what your getting just for curiosity sake.

And I just managed to get some more H4831SC yesterday... though I should scoop some up before the eventual shortage...

I wouldn't tell this to the "Jerk"... but I use 5/16" brazing rods as replacement chrony arms and actually prefer them over the OEM jointed ones.. Very cheap replacements... :grin:
