I am using 63 gr. of triple seven. Gun shoots great. But is this enough for whitetails inside 70 yards? i have a 50 cal. huntsman and shoot a 320 gr. REAL bullet.

What cal and projectile?

I would personally say yes, 63 grams of Triple Se7en is enough for Whitetail inside 70 yards. 63 grains of T-7 has about the same power as 70 grains of Pyrodex RS. I have personally shot a deer at just under 50 yards with 70 grains of Pyrodex RS and a .490 patched roundball.

Shot placement is always critical with every hunting situation but remember you're putting almost a half inch hole through vital organs of an animal. That size hole and the tissue damage it will do, will cause the death of that animal. Whitetail deer are thin skinned and not all that hard to poke a hole through.

Back in our country's early days when powder and ball was hard to come by, many times loads such as 50 grains of powder and a roundball were used to harvest deer. There are records of even smaller charges then that being used. These early pioneers were excellent trackers though, and I am sure that was all taken into consideration.

As long as you can place that shot at 70 yards everytime, I do not think you will have a problem harvesting a whitetail deer with that charge. I do not know how much more I would push the distance out of consideration to the animal alone, but for what you're planning, place that projectile and be ready to track if need be....

63g 777 would push a roundball and a small conical at what 1300-1500? If we are talking .50 cal. Maybe a little less. 40g Goex FFF will push the ball out of my Lyman pistol just under or over 1000fps.

I have shot 40 gr of 777 out of my flintlock. Excellent accuracy from 50 to 100 yards. If the shot placement was good it would kill a whitetail IMO. I would still use 80 gr to hunt, personally. Less chance of a squib at higher charges. Just my thoughts, I could be wrong.

I wonder how in the world 63 grains would push a 320 gr slug to lethal velocity? this guy is a bit fishy...check his other posts. I use 100 grains of triple seven and a 295 gr bullet. never would I use less.

There are people shooting much heavier slugs with little more powder then that taking game much further down range then 70 yards. For instance the 460 grain No Excuses are shot with 70-80 grains of Triple Se7en and they are taking large game animals at distances of over 100 yards. I personally think with the right shot placement that 63 grains of T-7 and a 320 grain REAL would do the trick.. Whitetail are considered thin skinned and not all that hard to penetrate. A half an inch hole through the vital organs will bring down most anything.

I commonly shoot 80 grains of Triple Se7en and a 250 grain Barnes Expander to hunt deer with and I will shoot much further then 100 yards with that combination. I also hunt deer with 80 grains of Triple Se7en and a No Excuse conical. I would not even blink if I had a 100 yard shot.

I know people who kill with a traditions inline pistol and 50gr pyrodex and 200gr XTP within 40 yards. Your will be fine. But be accurate and patient.

Yes... just make sure the powder is kept dry because you are at the bottom of the road for bullet speed/energy.

I would like to remind you thou.... what you have is a fast twist ML that's best suited for sabot/bullets. A similar trajectory load would be a 300 grain sabot/bullet with 75 grains.

I shoot patched round balls alot with one 50 grain pyrodex pellet in my 50 cal CVA hunterbolt. thats my small game and plinking load. Not to mention My most accurate load aswell LOL
