I think most of us have suffered from busted scopes ruin an outing at least once.Well I finally got a chance to try out the 300 win mag ammo but my rifle was not too happy with them. I only did two groups of three but both groups were 11/8 inch. I had some Federal 180 grain Trophy Bonded Tip which gave me less than half inch groups. I intend to give them one more try because after I got it sighted in for the Federal, which took some time, I discovered my vertical adjustment was not tracking properly. I removed the scope and sent it in to get repaired.
After I got home from the camp my box of 7mag came in and they were perfect. I also made a trip to Cabelas again and they had the 308 178 grain which I checked and they were also perfect. I guess I was just lucky to get one of the worst boxes of 300 win mag.
If your current mounts and rings are installed properly changing them should not affect your groups.Got the scopes back and one was repaired and the other, a Zeiss they said they could not find anything wrong with it. It was mounted on a Browning X bolt with Weaver bases and Warne rings. I checked the bases and found that they were loose. Apparently my screwdriver was biting into the sides of the holes causing it to feel tight. When I got my torque screwdriver which is straight I found they were a little loose.
The 300 win mag 200 grain averaged about 5/8 inch groups. About half of what I was getting before the scope repair.
The 308 was between 1/2 and 3/4.
The Browning X-bolt has got me puzzled. It is the one with the Zeiss on it. I was strictly going for group size so once I got it on paper I went from there. I put two shots 3/4 inch apart then the 3rd & 4th shot 5/8 inch apart but 2 1/4 inches below the first two with the same aiming point. The fifth shot was back up 2 1/2 inches with the first two shots. What the Hell??? I wrapped that one up and will deal with it later. I was at my hunting camp and on the way home stopped and picked up some Tally light weight mounts for it. Next time I get a chance I will take it out with some already proven ammo plus a spare scope in case it does it to me again.
Looks like the 300 and 308 will be happy with the ELD-X rounds. Now I just have to use up the 100 or so rounds of 308 Nosler Trophy 165 Accubonds.

The factor most likely affecting your group size is the shooter.
The 300wm with 200gr pills has enough recoil to cause most people to flinch especially as the number of shots fired increases.
Believe me WildRose, I know this well. I have cut my nose twice and kissed it several times since I got the 300 mag but the one giving me trouble is the 7 mag. I actually got the best groups with the 300 mag which surprised me a little since I was holding it so tight. I am not a little man, 6'2" and 205 lbs, so I can absorb a little recoil but I also am no "spring chicken" at 58 years old I can only absorb it so much before I have had enough. I have only put about two boxes of shells through it so far and once I get my data for a custom dial I will just confirm it once in a while but practice more with the 308 which is almost an identical rifle and waaaaaay more enjoyable to shoot.
First chance I get I'll get back out with the 7mag with more ammo plus a backup scope to see what happens. If everything is good I'll just have to take it back down to change the stock on it anyway as the rubber on it is breaking down and is sticky as Hell. Would like to put a McMillan Hunter on it which is what I have on the 300 and the 308 is the same design just not a McMillan. It is the stock Sako 75 Finnlight.

I got two boxes of Precision Hunter in 6.5 Creedmoor with the 143s from Midway.
Mainly because they were out of stock on brass, and I thought I could just fire form the factory stuff and get some shooting in. The ammo was in very good shape, and I was amazed with the accuracy I got with it. I hope to duplicate the load, I know where I'll start with the COAL, that's for sure....
