Does anyone have....

The ballistics for tc shockwave bullets? 250 polymer tip shooting 100 grains of powder. I can't seem to find it on the net anywhere and I am trying to sight my knight muzzleloader in. Thanks in advance.

I happened to see this infromation posted a while back on a ML site. I don't remember the site but I did copy the information.

Am I missing something, doesnt say how much powder the guy was using. Maybe I missed it.

I sited my encore in with these at 100 yrds and at 200 yrds I have a 6" drop
with a 150 grains of powder.

 

[blake]

The load was 100 grain Triple Seven.

 

[Steve-O]

Thanks Blake

100 grains is all that is needed....any more than that you are looking at incomplete burn and essentially wasting of the powder.

 

[gersdorf]

When I was shooting this weekend I was hitting about 1.5" at 50 yards and at 100 yards it was shooting about 4" high. Any suggestions????

Is that true for any muzzy load or the one in question?

Using 120 grains in a .54 Scout with Powerbelt loads and it shoots perfectly...after trying every other load in the book

Never tried it with less powder?

Plug in some numbers here to learn your trajectory. 4" high at 100 sounds good as long as you never go any higher. Some recommend a 4" high trajectory to give you the maximum point blank range on a deer (hold dead on and you will be no more than 4" high until it drops to 4" low at X yardage).

I would almost think a .54 cal would be better suited to handle a little more powder than a .50. With that being said my friend shoots a .54 with 80 grains of loose powder. Seems a bit on the lite side to me, but it seems to do the trick. I have seen it put an elk down. Whatever works. I must agree with Shredder - no point in shooting 150 grains out of a .50 cal in my opinion.

 

[Limb Chicken]

There is no point in shooting 150 grains out of any muzzy pellets or loose. They can't burn the whole charge. 120 grains max in my opinion.

When I zeroed my Encore this year I took the chronograph along for the heck of it and played with powder charges. This is what I came up with using a 250gr Shockwave or Hornady SST (same bullet).

2 T7 pellets
1698 fps

125 gr loose T7
2065
2070
2077
2049
2050

135 gr loose T7
2138
2140
2114

I dont recall exactly but moving from 2 pellets to 125 gr of loose put the bullet about 7"-8" higher at 100 yards. Dead on at 100 yards was approx 3" low at 150 with 125gr. Groups were 1.5"@ 100, 2.5" @ 150. Never tried 150gr. Recoil increases noticably with each increase in powder. I finally settled on 125 grains.
