Just wanted to ask and see what everyone's experience is with this caliber and bullet combination regarding whether it likes to jump into the lands or if they do better right in the lands. I tried it in my rifle with IMR4064 loaded at 2.800 as the hornady manual says and the best it did was about 1.5-2 inch group at 100 yards. Now I am trying the famous pharmseller load with this bullet along with big game powder and large rifle magnum primers. I did back mine of a couple grains at 44.0 grains to start off with and plan to go to 46.0 and see what the groups do just not sure what to seat them. About the longest I can fit in the magazine of my model 70 is 2.850 maybe just a tad longer but not much. Any advice would be greatly appreciated because this rifle is about to drive me crazy trying to find a load that it'll shoot good. Thanks
More info on the rifle is really needed here. Is it properly glass bedded? Are you using solid mounts and rings and proven scope? All mechanicals good? Does it shoot other loads and bullets well? All questions that need asking before I'd proceed. You can send it to pharmy like he's suggesting, but unless he knows model 70's like the back of his hand, you'll be chit out of luck.
It would also be nice to know where your lands are at, so you have a place to start that bullet. I personally run .020" off on my hunting rifles and then work up to optimum charge weight (OCW). You should be able to find a great load without too much fuss, if the rifle is solid mechanically.
