First of all, it is a 6ppc and I have been shooting benchrest for years. However, getting a new rifle a few years ago it took be some time to figure out what it liked. And the main difference is the loads it likes.
Starting with the old rifle it often liked the medium to hotter loads, in colder temperatures +30 gr N133 was not uncommon, of course depending on where it shot the best. I would say that old rifle normally shot the best in the range 29-30.5 gr N133 depending on barrel bullet and temperature.
Then, when getting the new rifle - which comes from the same producer of action, stock is different - it took my a lot of time to realize that the new rifle would not shoot the hot loads. It shoots the best in the range of 27 - 28, occasionally up to 28.5. Why is that? I mean, I have had barrels that loved those HOT loads on one rifle, but bringing this barrel to the new rifle it starts to spit some bullets now and then, and will not shoot consistently before entering the low loads. And there is shot great! I have won several matches with it.
Is there any common sense to this? The actions are the same (producer), stocks are different, but that is about it really.
On the positive side, except from the fact that the rifle shoots great, is that the brass lasts "forever".
Note that this is not me trying to force the rifle to shoot hot loads, just trying to understand what is going on and if this could be explained.
