I put together a Savage Axis in 223. I did put in an after market trigger, but is stock other than that. I mounted a Simmons 6 X 18 Pro Hunter (cost $60, trying to keep the cost down) with mounts that came on the rifle and a couple of rings that were in my extras box. I loaded up 4 different loadings to try and was waiting on a decent day to try them out. Today was about 45 degrees and just a slight breeze. I tried all 4 loads. Three of them did not impress, but were not real bad, in the 1/2" - 3/4" range taht would be in the 1" to 1.5" at 100 yards. The fourth load worked very well. I shot 2 - 3 shot groups at 50 yards. I shot at 50 yards, because I was set up for it and I had to sight in the scope and did not have time to move back to 100 yards. I feel confident that the groups would have carried about 2X group size at 100 yards because the 75 Grain bullets fly well out of a 9" twist barrel. The first one was very good and the second one was not too bad. I got some 55 grain SPSX on back order, but may not use them. The 75 grain BTHP shoots so well in this rifle and I have 500+ of them to carry me through the panic.
The rifle...
First Group and load data.
Second Group...
May have been my fault, that the group opened up a little. I had to single feed the cartridges in. They fit the magazine, but did not want to cooperate feeding out of the magazine to the barrel. Some of the others I had loaded up, fed OK. The OAL of the 75 grain bullets is 2.380" and were about .020" off of the lands.
One thing I also like about this rifle, besides the accuracy, is the weight... light, just 6.8 pounds with empty magazine and scope. Now that is what I call a walking varmint rifle.
Good Shooting and Good Luck
