The 7mm/300 Win Mag is fully up and running now! And she's a beaut! I did some initial load testing last week and worked on more load work up this week with the Berger 195 grain EOL. The caliber is a 300 Win Mag case necked down to 7mm to shoot the new Berger 195 EOL. The load I ran this morning was running 3013 fps average. We shot at 932 yards last night, and got some great results. Today, we went out to our 1 mile target, but could only get to 1715 yards with the heavy vegetation right now (we need to do some chain sawing!) We got set up and lasered the target to 1715 yards. At the 3013 fps I'm running, this bullet is supersonic to right at 2000 yards. We had a bad switching wind that would change from a 2 o'clock wind, then no wind and mirage would boil straight up, then switch from the 10-11 o'clock wind value. Once we got our wind call, we could make repeatable hits. I used to play with the 300 WM with the 225 BTHP and this 7mm bullet makes things a lot easier! Anyway, here's some pictures of our set up and shooting platform.

VERY nice!

What are you thoughts on the 7/300wm vs the 28nosler?

We debated a lot about going 28 vs 7/300wm. We looked at several factors.

1- brass cost and availability. 28 nosler is expensive at about $3 a piece. Norma 300 wm brass is about $1.10.

2- case volume. The nosler holds about 79-81 grains of powder for the 195 grain. The 300 wm holds about 75-78 grains of powder with the same 195 grain bullet. The case volume is very similar.

3- 7/300 wm chambering. Both rifles in the picture were chambered with the new PTG bore rider technology reamer that has a double stepped throat for better bullet alignment. This also allows for an increase in powder capacity and longer bullet seating, which closes the gap between the two.

4- loading and sizing brass. Since I already load for the 300 wm with high end match grade dies, I have all the FL, neck sizing, and bushing dies. The sizing of 7/300 wm brass is as easy as installing the proper neck bushing to size for 7mm, about a $15 cost.

Comparing all factors, the 7/300 was very attractive. I'm running the 195 at 3020 fps, and got it up to 3098 fps, but with some pressure signs. The 28 nosler is about 3050 to 3100 also, maybe 3150 with the right powder and barrel length.

It was a debated topic, for sure. I have been impressed with the 28 nosler, just not the higher cost.
