New to reloading 300wsm

When I was planning retirement 2004, Kimber came out with the Montana in 300 WSM. I loved my 700 Rem Stainless 338 WM with H&S stock. Little heavy for a mountain rifle. I bought a Kimber Montana 300 WSM.
My first loads was Win. Brass, Win. Primer (Original primer for reg. or mag) IMR. 4350 powder, Sierra,150 gr. 1 3/4" group at 100 yd. 165gr. 1 1/4", 180 gr. .560" group, Near 3000 fps. Used 180gr. Hornady interlock for deer, Nosler 180gr. partition, Caribou, Elk and Moose load. With the Montana magazine anything over 180gr., Seats to deep in the case.
With a 2.5X8 Leopold scope, nylon sling and 4 shells 7 1/4 lb. weight. Makes a great all weather high country rifle. Its the "Old Man".
 
I've got a Blaser in 300WM. The load I use is:

H1000 75 grains
Hornady 200 grain ELDX
Primers are CCI BR2
Stats - Average 2982.19
Stats - Highest 3002.42
Stats - Lowest 2962.12
Stats - Ext. Spread 40.3
Stats - Std. Dev 10.36
Energy 3921

Groups 1/2" at 100yards

Just qualified on our new 400 yard range easily hitting the 4" steel plates.

 
In my 300 wsm, 200 ELDX is about 65gr at 2900ish, 178 ELDX is about 68gr at 3100ish. Both loaded to mag length. I worked off of the hornady book for the charge. Both were WAY faster than described in the book
