Archery season here in Montana has been a blur and September is almost gone. As I look at the calendar rifle antelope looms and will be here quickly. October 6th is the opener and I plan on being there and ready. So yesterday I decided to go put some more trigger time in behind the Weatherby and try to find out which bullet it would shoot best. Often a gun will shoot one type of bullet or even one weight of bullet much better than others. With 3 new boxes of ammo, each a different bullet style, I set out to go attempt to shoot some 200 yard groups.
Now shooting groups is actually a fairly difficult thing in my opinion. It’s very results oriented and one bad squeeze messes up the group. Eliminating the human error is all but impossible. I tend to shoot better at longer distances so I like to shoot groups at 200 yards if possible. This day I had three rounds to test out. A) 180 grain Accubond B) 180 grain Norma Spitzer & C) 180 grain Nosler Partition
I started out by cleaning my rifle as it’s only had about 40 rounds through it and I’m trying to help break in the barrel even though it is hand lapped. I shot a round to clear the barrel of oil and then started in on my 200 yard groups. Each group I’d shoot 3-4 rounds. Sometimes you know when you made a bad shot and I like to eliminate that shot and shoot a fourth so that I don’t have to restart on a new group and burn through more ammo. I shot a group with each different ammo and then cleaned my rifle once it had cooled down. I also made sure to let the barrel cool down some before continuing through my groups. I shot my first round off the concrete bench but found out it had a little wobble in it. I was wondering why my reticle was moving left to right on me and that was it haha. For the second round I laid prone off my bipod.
From my first round the 180 grain Nosler Partition was the easy winner. I didn’t take an official measurement but it was well within the 1 MOA standard and close to a 1/2 MOA group. Plenty good for a rifle that I’ll rarely push past 5-600 yards in a hunting scenario. Now between groups I’d been shooting my other rifle, a 300WSM at distance trying to dial in my ballistics through my Kestrel, so by the time I got into round 2 of my groups my shoulder was getting a touch sore and my shooting seemed to go downhill a bit. I still put some good rounds downrange but had more flyers it seemed. The Spitzer and the Nosler Partition were close and the Accubond just didn’t perform. To end my session I took two of the Nosler partitions and took shots at metal gongs at 458 and at 620 yards and got hits on both. I’ll be shooting another round here in the next week or so to pick between the Partition and the Spitzer and then from there zero in and start extending the distance. With antelope coming and general rifle just around the corner I’ve got my work cut out for me but things are looking promising given I get a few more quality days in at the range. Setting up and getting acquainted with a new rifle is a process but doing it right from the beginning makes all the difference and helps you develop a level of confidence with your rifle that will translate to more one shot kills in the field.
