Here is a question. I want a accurate, target and hunting bullet.
Here in Norway, the most popular "match" caliber is the 6.5x55 Swede. It's a good caliber in all aspects. But it don't have heavy bullets. Good B.C and but not heavy enough. As far as I have read, a bullet behaves perfect, when it has high B.C, weight that is proportinal to its lenght, so it has downrange energy, and speed.
The 7mm is between the 6.5 and 308. So it has better B.C than 308 and higher weight than the 6.5's. The new Sierra MatchKing has a B.C of 0.8??,Trying to remember) And weighs a 175 grains. And you have the 162 grain A-max. As far as I know, there arnt any heavier bullets. Maybe som 200grains from custom bullet makers.
Now, it has high B.C, and seems to have good weight. I would think that even higher weights might come, or just from custom bullet makers. It has the best from both worlds. Now, what kind of speeds would be needed to give these bullets an edge at the range? Most of what I have read it seems to be, that pepole are trying to get around 850 m/s to retain barrel life, and get a go aerodynamics.
Barrel life is of concern. A .280 Rem, gets the same speed, using same bullet, and same powder as the 7mm Rem.Mag, using 10 grains less powder. 54 grains to 64 grains.,175 grain Nosler Partion, in a book I read).
So Case design plays an important role! How many degrees the shoulder should be, how long a neck, how fat, and how long the case body should be.
And by the way, this is in a Tikka 695 action. But I am defenetly going to be using a Wildcat. So any hints on what I should build, is appriciated. I'm going to buy a book about wildcats, to find my perfect caliber. But please, share some thoughts about this. I don't think I need any magnums, since I have proved it dosnt need to be a magnum to obtain the same speeds as a non-magnum.
What whould be interesting, is if some of you guys, whould share, what kind of case design you think would be perfect for,most likely) the Matchking and A-max?
