Anyone shooting a Austin Halleck 320? I need a good starting load.

Hard to say without some definition on what bullets or powder you like.

I notice you buy a good bullet for that Omega.... ie... 220 DC's.

So why not go a little different with this one --- say perhaps 245 gr. Barnes Spit-Fire or 200 gr. Barnes XPB... both easier loaders like your Precisions & this time you are trying copper hollow-points that perform as well as your leadDCs.

No matter what powder you choose, always start with70 grains & either stay there (or) move up in 10-grain increments until shot groups spread -- then back-down 5 grains. I never exceed 110 gr. loose or 130 grains pellets using my 777 FFF loosein my Omega. Stay real close to what A & H recommends -- especially using 777 FFF loose.

Like Triple Se7en I usually always start my inlines with 80 grains of powder and work all loads upward from there. It not only gives me a good base of information of how the projectile will react, it also lets me tune the rifle the only way I know how.

I just adjusted/edited that post to read 70 grains. I think I will do that from now on - because of no mention of what powder the thread-starter uses. 70 grains 777 is like most 80 grain loads using most other brands.

Better-yet, this is the last time I will answer a thread that contains absolutely no clue what the poster wants to shoot - or the powder they intend to use.

Too darn complicated this way! I'm done guessing!

Thanx guys, was looking at the Barnes Spit-Fires, have heard a lot of good things about them. More than likely shoot 777 since that is all I use in my Omega and Knight's. Always seem to end up right at 100 grs. load no matter the bullet or the rifle. I tried 3 pyro pellets in an old disc rifle I had with the Barnes Expanders and it shot around an inch but the recoil was a hell of alot more than I was comfortable with.Did kill my first Bull with that load though.

I shoot a 320, have for 4-5 years now. Everything I dhoot in it I have been shooting @ 100 grains t7. It will shoot just about anything you want to shoot sabot/projectile wise. I hope it shoots as well as mine has. It is an extruded barrel so the may be places in the barrel that the sabot slides down easier than others - but it has zero effect on perfromance for me.

Is your a new(er) one from Provo, UT or an older one from Weston, MO.
The two that I have are from Weston.

Iwas out last weekend with it and put the information here. But you will notice I did switch to 110 grains for this shoot.

The accuracy of this gun has been really good with all the combinations of bullets I have shot from it. I normally hunt elk with a .458 300 grain Nosler Partition and deer with a 260 grain Nosler. But recently I have been shooting a lot of Speer Gold Dots and I am pretty sure I am going to use them on deer. We can not use the 200 grain projectile in Idaho from a ML but that really might be an interesting bullet if you can use it.

Ignition with a 209 is much more reliable than ignition from a #11, not sure what might be legal for you. An you might want to fashion yourself a weather shroud (the bakealite shroud they give you will not last long before it is burnt up up) it can blow back a lot of material, up and out under your scope if you are using a scope. If you are using a #11 and no scope it really is not a problem.

Here is a thread....

Thanx sabotloader, I PM'd ya on Modern Muzzleloading so disregard that. Mine is the newer one from Utah.

Which by all accounts has a more reliable receiver & bolt - (the Provo model).

I have a lot of other ballistics and/or projectile information if you need more.

You will probably need the MMP HPH-24, Harvester, TC mag express type sabot - the bore is probably right at .505/.506... That is something you will have to check for your self though.
