Re: Anyone own a 7mm 300 Win Mag?

Got my 7mm-300 WM back a few weeks ago. Been meaning to post pics and tell about it but got busy, so here it is.

28" Match Grade Stainless Steel Barrel
-Sendero contour turned down to .780 at the muzzle
-Hand Lapped
-Fluted and threaded for a break
-Custom Muzzle Break

180 VLDs
76.8 GRN H-1000
Rem Brass
CCI 250
3174 AVG

162 AMAX
79 GRN H-1000
Rem Brass
CCI 250
3340 AVG FPS










Here is my 2010 Antelope. It was the first animal taken with this gun. Shot him at 515 yards with a 162 AMAX. Wind was crazy that day, gusting 20 mph.

    Sid.. Awesome rifle!! Looks like you are getting the same velocity we are.

    Nice stick!

    Sid, your youtube videos are funny. I love the one where you said, "and we ain't even shootin a husss kee maawwwww."

    So, what is the ballistic difference in a 7-300 v. a 7mm Dakota, 7STW?

    I think that they are pretty comparable. I just opted for the 7-300 because of the lower amount of powder that it burns compared to the Dakota, STW, or Ultra Mag. I didnt want all the powder consumption and most of all I wanted to keep recoil to a minimum. Even though I was planning to put a muzzle brake on whatever I built, I really like low recoil, it seems to make me personally shoot much better.

    How did u know it was me in the Youtube vid?

    How close to max are those loaded? I would think they could be going much faster.

    Pretty much maxed out. The bolt was heavy at 77.0 of h-1000

    Sid, from what I have learned with the one I did, you must be using RP or WW brass? I just want to say if you ever go to RWS brass back her off to close to 70 grains and work up again. The lower case volume of the RWS sends the pressure up... way up! I think when we changed from RP to RWS we dropped like 4 grains and still had he same velocity as we did with 4 gr more in RP brass. The RWS weighs 48 gr more per case and is some very tough brass. After fireformed it really helped us with lowering our run out.

    I have seen my buddies son (12) poke an antelope in the heart at 650 yards with the 7mm/300 win. and the 180 Berger bullet preformance was great. I cant wait to see how it does on their Elk and Muley's this year.
