Don't seel the 162gr Interloch short. It's heavy enought to hold together in the 7mm mag. I'd bought 140gr Nosler Part's to hunt with in my 6.5x06 and broke it in with 140gr Interlocks. Still have never killed any animal with a Partition but have killed two elk with two shot's with that 140gr Interlock.

I hear you Don, I wouldn't feel bad packing the Interlocks, but since I purchased the 154 gr Interbonds I'm going to give em a try and see if they shoot to satisfaction. I'm using RL 22 (should have gotten RL 25 as the max load is about 100 fps faster) Win brass and both CCI and Rem Mag primers to begin with. If'n I can't get a satisfactory load I may go back to the Interlocks due to the accuracy or try the Accubonds in 160.

Final hunting loads determined and shot at extended ranges

Well, I finally settled on my hunting loads for my 7 Mag and 30-06. Took a little trial and tribulation but I'm pretty confident with the loads I've picked.

Regarding the 7 Mag as I mentioned in another thread I had tried 154b gr Interbonds, 160 gr Accubonds, and 162 gr Interlocks. With these loads using RL22 and IMR 4831 I couldn't get better then 1 1/2 inch to 2 inch groups at a hundred. I would've used one of em if it consistently gave 1 and 1/2 inch groups but all groups varied to 2 or more inches and I wasn't satisfied at all. I was wondering about my Mag which shot 175 gr bonded bear claws (factory) very well, but none of my reloads. As all of the bullets I tried were boattails my gunsmith advised me to try a flat base bullet. He explained that the cut of the crown on my barrel might be affecting the flight of the boattails due to how the gas escapes when the bullet leaves the barrel. He said I could either get the crown recut for a different angle or try shooting some flat base bullets. I opted to try some 175 gr Interlocks and used the Nosler recipe for their 175 Partition and went up to their maximum load of 62.5 grs if RL22 listed at a 2970 fps muzzle velocity. This was giving my consistent 3 shot inch groups at 100. This week I made up some more to take back out sight in and shoot again. After sight in my groups were to my liking. Here's a five shot group at 100.

300 yard group

I then took the target out to 300 and shot two groups. One of which I will post here. I've always pushed the use of a premium bonded type bullet but after taking what Don said about the Interlocks and elk in this thread and seeing that the 175 gr has a BC of .462 and SD of .310 and reading about many hunters readily taking elk and moose with this bullet I feel confident using it. That big 175 gr bullet with that long shank traveling at those speeds should give a good whomp on a bull if'n I do my part. Here's one of the 300 yard groups.

Regarding the -06

On the recommendation of my Dad I tried the 168 gr Berger VLD Hunting bullet using RL22 and going up to 62 grs as a max load. This should be pushing that bullet around 2900 to 2950 (I'd like to chrono them to know for sure). This load does make that -06 kick hard, however no undue or hazardous pressure signs on cases and no stickiness in the action. This gave me consistent inch groups at 100 yards so I took it out to 300 and was really impressed with how tight the groups stood. With both the 7 Mag and the -06 I went with a 3 inch high sight in at 100 which is putting me on the money at 300. Here's one of the 300 yards groups. The -06 will be used on a Sep. private property tag cow elk hunt and for my buck antelope tag in Oct.

400 yards

I then shot both rifles at 400 yards each a four shot group for both. Wasn't under the best conditions as I shot after walking the 800 yards, 400 of them up hill, and back under a 98 deg sun. I was sweating up a storm and didn't really rest long enough to get my heart rate and breathing down. But, I still managed about 8 to 10 inch groups which would've hit the shoulder of a deer or elk. In this pic the 400 yard targets are on the far hill the rifles pointed at.

Feels good.

To find a good load and bullet to have confidence in and shoot them at extended ranges to see where they hit. A great confidence booster. I may shoot at 3 and 4 hundred yards a couple more times clean em firing a fowling shot and then be ready when season opens. If any one has experience with the bullets I'm using I'd be glad to hear your thoughts on them.
