9.3 bullet test started. pics posted in #1

thank you Johnn for the IMR 4064 load. seems i will use something like that for the test or very close.

For basically one of the first;) 'kicks at the cat', it's a load that has worked well on paper. That being said, IF the '.366 Wagner' got the call for a field trip tomorrow, that's likely the load I'd go with.
 
I have some experience at testing ammo.

Results to us hunters should relate to the distances we hit game at. In an ideal world, you would shoot your mud (or whatever) at 50, 100 and 200 yards. That would could cover 90% of our actual hunting shots.

I suggest you move your 20 yard test to 50 yards. (1) It is a more realistic "hunting" distance. (2) bullet yaw at 50 won't be as big and yaw can really screw up bullet performance tests.

If you can hit your target medium at 100 yards, that is much better, since yaw will be gone.

Make ammo in two powers. Full power and a reduced powder charge so that the 100 yard velocity is more like a 200 yard velocity. This way you can give us a 100 and a 200 yard performance. The POI would not shift more than an inch.

For the reduced power load (the 200 yd simulation) just reduce the powder charge by 4 grains for all bullets. That will be close enough for our purposes.

I would look to the 50 yard test to make sure the bullet does not blow up and the 200 yard test to make sure there is still some expansion.

Some good suggestions there: It seems to be taking "forever" to get this under way in actual shooting tests. I've only used the 286 Hornady and 286 Nos Part. on game so far, but expect to give the 250 AB a workout this year.

The sectioned bullet pics actually give a pretty good idea of what can/cannot be expected.

I've tested bullets in dry glossy magazines at close range (10 to 20 yds) and I expect that's much like hitting heavy bone. Penetration is only about 8" regardless of caliber or premium bullet. But it does give an idea of one compared to another.

These old 9.3 guys, I'll probably have my .375 test before them....;) And that's going to be with a .375 Ruger! (that should motivate them! lol)
 
I think the plan is to test them on game animals, so they're waiting for the season to open. I think they are also keeping a low profile because they're not sure if they are going to
get enough tags. All I can say is that you better start making room in your freezer, because come December they'll be giving it away. :)
 
While we are waiting for the test has anybody ever tried to improve the 9.3x62 like an Ackley improved? I wonder if a 40 degree shoulder would make a difference ?
