Where is a ballistic chart for Triple Seven powder loads?

Northslope Nimrod · September 7, 2009, 06:31 PM

My dad is muzzle loading this year for the first time. He is shooting 300 grain sabots with Triple Seven pellets. I need a ballistic table to assist in sighting this rifle in. He was told to use three pellets of powder.

NN,

Go here: http://www.hodgdon.com/ml-warning.html for Hodgdon T7 load data. Check the box that says "I have read...........information below", then click the Get Muzzleloading Data. That will take you to the 20 page file that lists loading data for T7 Pellets, loose powder and Pyrodex.

Did you try Hodgdon's web site: http://www.hodgdon.com/index.html. It contains a downloadable .pdf file with loading data for 777. Click on Products, then Muzzleloading, then Triple Seven. The click on the Data tag on the left side of the page just below the words Loading Notes (NOT the word Data in the line near the top of the page).

Damn. Fingers beat me again. That's what I get for proof reading.

Thanks. However, I can't see any trajectory tables in that PDF. Where are they?

Trajectories depend on the ballistic coefficient of the projectile; Hodgdon's doesn't make projectiles. You need to calculate the trajectory for your projectile choice(s) using Hodgdon's energy/velocity data. There are several ballistic trajectory calculators available on the internet.

Here's a short chart from Traditions which lists the trajectory for 1 sample load of 150 grains of powder with a 300 grain saboted bullet.

Darn. This shouldn't be so hard. I can't find the Ballistic Coefficient for my sabots on TC's web site.

I am shooting two 50 gr pellets of Triple Seven...covered with a 300 grain sabot from Thompson Center.

I want to sight it in at 25 yards. I would like to be about 1 inch high at 100 yards. So, can someone tell me where I should sight in at 25 yards?

OR can someone tell me the BC of my sabot and point me to a calculator where I can figure it out?

Long range hunting with a ML takes a lot of practice. According to "The BlackPowder Journal" vol.2 number 5, Oct.-Dec. 1997, sabots weighing .270gr will rise 2"-3"@ 75yrds., and drop below line of sight 2.5" to 3.5"@ 150yrds. A 10mph cross wind can move a bullet 9" to 17". Most hunters in a test had a difficult time making a kill shot past 150 yrds. For a .270gr sabot they recommend sighting in to hit dead on @ 125yrds., enabling a shooter to hold dead on out to 150yrds. This was with 90gr. (most accurate load in that rifle) of powder. Hope this helps.

I would NEVER attempt to hunt deer with any rifle that was sighted in only on a 25 yd range. You owe it to your quary to get to a decent range and do a true 100yd sight-in.

You are incorrectly assuming that you can actually see 100 yards in the woods you hunt. Such is not the case here, and fifty yards is virtually all the farther you can ever see here.
