I decided to have a rifle made rather than rebarrel my 7mmEclipse.
About a year and a half ago, I had Nate at SSG build one of his 7mm 300WSM LRH Rifles for me. I have been using it for beanfield whitetail deer hunting here in Georgia. It has performed excellently using Berger 180 VLD's at about 2800 fps. There are are additional barrel vibration nodes at higher velocities but the 2800 fps node gives me both good hunting and targeting shooting results. Hopefully, at the lower velocities, my barrel should last a lot longer.
I have killed a few whitetails with it and the 180 VLD took care of business out to 460 yards, my longest kill shot.
I have been using it for long range target practice on the Silhouette Range out to 500 meters and on the 600 yard HP Rifle Ranges learning how to shoot at longer distances.
Just this past Monday I shot at a 1000 yard range for the first time. With winds at 2 to 8 MPH, 95F, 32% Humidity, 30.23inHg and elevation of 850 feet measured by my Kestrel, I was happy to see that the calculated range dope for elevation gave me near center vertical impact on the F-Class Targets I was using. The picture below is of my best group of about 0.25 MOA at 1000 yards using the initial MOA elevation setting given by my Ballistics Calculator. Working on getting 5 shots like this.
The gusting wind during the session was another story. I have plenty of room for improvement in reading wind.
This has given me a lot more confidence in my Chrono, scope, rifle and cartridige ballistics. Really looking forward hunting season this year.
In regard to the 7mm Rifles, I have been very happy with both my 7mm Eclipse and with my SSG Custom 7mm 300WSM rifles. They are both more than adequate for my needs.
I agree with much that I have read here on the forum by a large collection of very experienced Long Range Hunters that up to 1000 yards the 7mm should do the job on whitetails. For shots on Elk, Bear and the larger northern whitetail deer beyond 1000 yards, I would use a larger caliber rifle.
