Went again yesterday afternoon. Ranged out a full 100yards. I tried 90-120 grains of Triple 7 with both TC Maxi-Hunters(435 gr.) and Maxi-balls(430gr.). Ended up being the 90 gr. loads were the most consistent and both bullets had essentially the same POI. I was able to keep the shots inside a 4" group at 100yards with both. Not overly impressive groups but adequate for elk. The concern I have is that 90 gr. only produces 1260 FPS and 1540 Ft. Lbs at the muzzle.
Does this seem a little light for elk or does the mass of the bullet make up the difference. I am thinking it will still shoot completely through on a broadside shot out to 150 yds or so.
Anyone have experience with comparable loads?
Would Pyrodex possibly shoot tighter groups?
Thanks for your input.
Lead bullets kill better than there paper ballisitcs would indicate. Judging most BP arms by the energy criteria alone is a mistake. The bullet diameter increases effectiveness even at what would be very low levels for a modern bullet with a pointed nose and a copper jacket. These HAVE to have velocity to work. The large diameter bullet simply needs adequate penetration.
One must remember that the 1/2 ounce trade ball was the standard big game projectile in the Western US from before Lewis & Clark till about 1870. It was used much longer than that in Canada by the natives if my information is correct.
It has become popular to denigrate the round ball as a hunting projectile. Just like the advent of the various magnums has supposedly killed off the 30-06. Its largely hype generated in order to sell products for companies advertising in magazines or funding people to use their rifle/caliber/sabot/bullet etc. If the RB is good enough you don't need what they make. Thus the RB is bad, deficient, will not penetrate, etc etc.
Used within its range, 80-100 yards a .530 rb WILL kill elk easily. With good shooting and good luck it will kill farther but bullet drop from line of sight and wind drift becomes a problem.
Hunters will have "problems" with any firearm they hunt with regardless of projectile if the shot is poorly placed. Failure to kill quickly or disable is ALWAYS related to poor shot placement or using to light a bullet in something like a 243 or 25-06.
Animals can cover a LOT of ground in just a few seconds. Thus a deer or elk that can stay on its feet for 10 seconds, may go 100-200 yards even though its dead in 10 seconds. Thus a good kill shot can result in the animal making tracks if the spine, brain or pelvis is not struck.
I did base of the throat shot on a mule deer doe with a 16 bore rb at 50 yards taking out the heart and she still ran 50 yards. Not very well but she *was* running.
I have seen them run much farther shot in the chest with 7mm mags, and live a lot longer shot in the guts with it.
My concerns are over the slow twist, if you have such a barrel, is that even a perfectly placed shot may miss the vitals. I had this experience twice last year with 45-70 commercial ammo (the "new" bullet design stinks) on mule deer and can tell you it WILL interfere with clean kills or at best turn a good lung shot into a green mess at field dressing.
