accuracy question
#21
The charge, bullet and sabot were identical with all six of those sabots. The three that have the torn bases, passed through the muzzle brake (normal), where the 3 that bases are just expanded, were shot without the brake (normal). With the base expanded as it goes through the radial brake, the brake tears the edges of the sabot.

I've done this hundreds of times. It just makes no difference. This was really popular many years ago. Just no justification at all in a lot of ML'S. But if it gives you confidence do it. That simple!!

Went out shooting yesterday and noticed that where I lined up my sabot made a difference in accuracy. If I lined up the gap between petals with the front sight my groups were tighter and more centered. Is this just my gun or a characteristic of muzzleloaders? It is something else I will have to keep in mind when I load up for hunting.
I tried doing a trajectory chart for my 290gr Barnes TEZ bullets because I plan using them during hunting season. Setting the scope crosshairs on the bulls eye the shot at 25yds was 3" low. At 50yds it was 1' low and 100yds it was 1" high. I am still learning how to use trajectory programs so I need some feedback. Is this in the normal trajectory range for a 290gr bullet being pushed by 100gr of Blackhorn?

Follows is a calculation using the information you provided about your load.
Note the chart indicate your 25 yard impact shouldn't be 3" low, if it is 1" high at 100 yard. The 25 yard impact should be about 1/4" high. The calculator shown here, has been very reliable for me, and all my shooting; i trust it.

The original poster stated and asked the question about indexing sabots in the same spot everytime when loading. Ive done this hundreds of times in Knight Extremes, Knight Elites, Encores, Triumphs, and even the Savage shooting smokeless and there was no difference. Now there is a chance he just has the perfect scenario and everything is just working perfect. The sabot/bullet combination is obturating very fast and he does see a difference. And if thats the case i would do it everytime. Being consistent reloading anything is always good if it works better or not.
Semisane brought up another good point about possible bullet slipping. Lehigh actually puts slits on the side of the bullet to help keep bullet slippage to a minimum. Again, it doesnt matter if the sabot slips, or the bullet slips in the sabot, to me its slippage either way you look at it.
When you take a look at the good long range ML shooters. I mean the guys that compete shooting paper. I dont think its by accident they mostly use 45 cal or smaller ML'S. I think its all about getting the bullet to bump/obturate to lock into the rifling. The faster this happens the more accurate the bullet will shoot.
Not to get off the subject, but im a hunter. I dont care about 95% of this stuff when hunting. My hunting range is between 5 yards and 200 yards. I tested weighing Bh209 against volume measuring. The difference if any is not worth the time. If i shoot a one inch group at 100 yards volume measuring, or a 3/4 inch group weighing whats the difference?? I can assure you whatever im shooting wont know the difference. Just like at 200 yards i can shoot 2 inch groups volume measuring. I might be able to shoot 1 1/2 weighing. Is the game im shooting gonna know that 1/2 difference at 200 yards?? NOPE!!
I feel the same about bullets and shot placement. Lots of guys say you gotta hit them in the right place. Well thats true, but not reality for me. I get excited when i hunt and im not shooting off a bench or even a rest. So i prefer to use the best bullet possible cause im not going to make the perfect shot. I might be an inch or two off from the guys that do everything perfect. Nothing is ever perfect for me, thats why i use the best bullet possible. Here again, my way is probably not the best by any means but its reality for me right or wrong.

Personally I a line mine so that two rifling are showing on each petal of the sabot and none are in the space between. This takes a bit of doing, but I believe it has cut the amount of fliers down till I know who is responsible for any I get.

I think i would full form sabots if i was as critical as you. People do this with sabotless bullets a lot. They run the bullets down the barrel or a cut off piece of the barrel to engrave the rifling into the bullet. Then they align the bullet engraving with the rifling and load there ML. You could do the same thing with a sabot using a tight bullet and just push them right down the barrel with the breech plug removed. Ive never done this but i think im gonna try it and see how it works. But i think flyers are from inconsistent diameter sabots. When a sabot all of a sudden loads really easy in comparison to the other bullets you already fired its almost a guaranteed flyer. When i was shooting for groups when this happened i would fire that load down range not at the target i was shooting at.
