30-06 on Moose
As mentioned by many before this post, try heavier bullets and maybe different brands. The 150 grain bullets in 30-06 are lighter jacketed, and more designed for Deer. The 180 has a heavier bullet jacket construction for Moose and Elk. The 165 is a compromise between the two, and work well on game. I shot 165 grain Speer Hot Core and 165 Hornady Interlock on a lot of Elk, and had no problem with them. Usually one shot was enough.
The 1600 Series Husqvarna is one of the best of the 98 type Mauser rifles for hunting. You might make a shim from an old business card, about 1 1/2 inches long, and put it under the barrel about 2 inches from the fore end tip, and then try shooting the rifle. This will put a slight upward pressure on the barrel, and a lot of sporting rifles of this design have a small wood pressure pad at that location. Also, the recoil lug on the front of the receiver MUST bear evenly on the wood to absorb the recoil. This is one area where a small bit of glass bedding is a great help. If the back side of the recoil lug does not touch the wood or only a part of the wood, the rifle will not be accurate.
For a Hunting rifle, a three shot group is a measure of accuracy. The first one out of a cold barrel, and two more. The biggest thing is where the first round will land on the target. If you are shooting five round groups for accuracy, then this is a bit of an excess. On a Varmint rifle, yes, but a Hunting rifle is carried more than shot. Usually only one or two shots a day are normal, with maybe a follow up shot needed. If you have done a lot of hunting, you will know that most game is shot well under 200 yards, and the biggest percentage is under 100 yards. You have enough accuracy for that right now, but try some heavier bullets.
If you look at some of the bullets used for 30-06 for shooting targets, they are in the 165, 169, 172 grain weight. If the target shooters thought the 150 grain bullets were more accurate, they would use them more. The original 30-03 and 30-06 loads were 220 grain bullets, then 172 grain for the Military.
There is nothing wrong with the 30-06 for Moose Hunting.....just needs a bit of tweaking on your part.
