100 grns loose pyrodex,370 grn t/c bullet. works well for me. Good luck!

This year my boyfriend and I both used 110 grains loose powder with Barnes Spitfire TMZ 290 grain with great success; one bull and one cow down with a shot each. Shooting at the range this offseason he's kept the same setup and has been consistantly shooting just around 6 inch groups at 100 yards. I have a TC Black Diamond stainless and he has a Knight MK-85. Both .50 cal.

We've been pretty happy with the setup thus far.

  six inch groups. When we went shooting yesterday we where shooting groups that where closer to about 1.5-2 inches at 100 yards. I think I might be doing some powder adjustments to see if I could tighten that up a bit.

Let me rephrase.. 6 inch groups have been at worst.. and in whatever weather may come on the olympic penninsula. He shoots 5 to call it a "group"... If you call 3 a group he's been consistantly shooting 2-3 inch groups. Also... are you using a scope to adjust powder and bullets? Because his is also keeping it to open sites. If you're getting 1.5-2 inch groups of 5 at 100 yards ... you should be professionally competing.

im shooting 1 inch to 1.5 inch groups at 100 with both my muzzys one open sites one peep site you might be pushing to hot i would back it off a bit

Sorry I wasn't trying to sound like an ass earlier. We are shooting 3 shot groups with 100 grns 777 loose.  300 grn Hornady SST bullets Williams peep sights. With both my Black Diamond and my Knight Big Horn. Also if you didn't notice I live is Shelton. So I would count weather out of the equation.

Out of curiosity, are you cleaning the gun after every shot. every other shot or every group. When we are at the range we clean after every shot or every other shot. I know when you get to much fouling in the barrel your gun will loose accuracy. Also it might not be the powder. It could very well be the gun. I know my Black Diamond hates power belt bullet's. They where all over the place. Couldn't get any kind of grouping. But I hear of people who love them and there gun's love them as well. I'm just wondering if you couldn't get better accuracy with your shooting by switching something up. Besides the sst bullets, I've used the Dead Center bullets with very good accuracy. Just a thought. Take it with a grain of salt.

Generally we clean after each group. Its nice to know what my gun will do a little dirty knowing that my one shot elk this past season isn't necessarily par for the course. Cleaning after each shot would seem slightly excessive to me, just knowing at some point I'll most likely have to shoot more than once.

With open sites as I said.. if you are getting 2 inch groups you are amazing. Especially since TC has no accuracy guarantee at 100 yards, and Knight promises only 2.5 inch groups... and Savage promises 1.5, both with the following assumptions in place:

To continue the accuracy quest, a few things are presumed. It is presumed that you have quality steel bases and rings, a quality scope, current formulation MMP sabots of the same lot number from MMP, you are using powder with the same lot number, and you are sorting your bullets by weight. There are no 'bench rest' 209 shotshell primers, but it is presumed you are using the same brand and the same lot number of 209 primers as well. Many purported 'accuracy issues' have been traced to loose scope bases, or reticle float inside a scope tube. If the reticle in your scope does not return to the exact same spot after recoil, there is very little hope of accurately gauging your progress. A solid rest is also assumed, as well as good range conditions. Gusty winds and large caliber bullets do not mix particularly well. Consistent loading of your sabots is also presumed. Seating pressure affects the burn profile of most any small arms propellant. Using 10 pounds of ramrod pressure then 50 pounds of ramrod pressure for the next shot cannot help promote accuracy.

My black Diamond hated the power belts as well -

I am with Hirshey on the group thing though. I am not sure how you can get a sub 3" group when your sight is taking up atleast 3" of the target at 100 yards

[bobcat]

I'd be very happy with a 5-shot 6 inch group at 100 yards. I just don't shoot that good with open sights.

[Blsum]

When I talk about cleaning every shot. I use one or two patches with bore butter to loosen everything up. Then I use dry patches until most everything is out.  I don't plan on taking the time to clean my gun before reloading, after I've shot at an animal, and I wouldn't expect anyone else to. I want to be ready for a follow up shot. If I need one. 

Like I said before. I'm sorry if I sounded like an ass. That's not what I was trying to get across. All I was implying was that I thought a 6" group was a little big, and was trying to suggest that there where way's to tighten the group up. If your satisfied with your groups then don't change anything.

I understand wanting to know where the second shot will go, without cleaning the gun. But I don't think you will need five shot's to kill an animal. So why not clean after two shots or even three. If you need more shot's than that to cleanly kill an animal with your muzzy, then maybe you should think about putting your muzzy down. just my  take it for what it's worth.

[Dirty Mike]

this is my groups i got at 100 yards when i put my peep site on that's  6 total shots all with out cleaning between as you can see where the 6Th one was, funny thing about that is 5 of the shot were by me at the 6 was my buddy Justin just to see how it did, since then me groups are 1.5 at 100 will my big horn 26 inch barrel 100 gr 777 300 grn sst. my knight wolverine has  2 inch groups at 100 it has a 24 inch barrel using the same charge and bullet, i am no Sharpe shooter by any means i shoot off the hood of my truck using whatever as a rest  .and i personally know 6 people that have under 2.5 inch groups there is no reason why you shouldn't get under 6 inch groups

[Blsum]

  Thanks Mike. This is the exact reason why I said something. Mike, Justin (hilltophustler), and I are always going out shooting, testing and practicing.

Where at on the Oly Pen. is your b.f. If you would like, I would be willing to go out shooting with you and him (or just him if he want's). To see if we can get a little better accuracy out of your guns.

[hirshey]

I chatted with my boyfriend tonight and he thought I might want to state that I have an unconventional definition of a "group". I know most people measure the two furthest apart shots from their centers and call it a group.

I recognise now that I throw the term group around loosely as the furthest shot away from the bullseye.  For example in that photo if those are 1 inch squares I would have said I was shooting a 3 inch group. I don't know how I came about that.. I suppose its because your intended goal is always the bullseye so I don't care how close they are together if they aren't on target.

So he told me his "groups" are much tighter than 6 inches. He lives part time in Port Townsend and part time in Chelan.. I'll run it by him.

I suppose I'd have to see it to believe below 2 inch groups at 100 yards after all the literature I've read today post-feud. Maybe we will have to do that just to teach me a lesson if nothing else.

Yeah, my TC has shot well thus far (it is a hand-me down from my mother) with pyrodex select... both my TC and my parents and boyfriend's Knights don't like pellets. Loose powder. Powerbelt bullets have given us decent accuracy but apparantly some of our family and friends have had trouble with expansion, and have lost a few animals. Some of our family friends still swear by them though. It was my mother's last season with Knight's bullets when she couldn't get one down her barrel (second shot, cleaned well the night beforehand) this past deer season and lost a buck to it. That's one reason I like the TMZs so much.. they glide down the barrel for me.

OK took me this long to get my gun sighted in. Love it. My buddy and his dad have been muzzy hunting for a long time. I will be hunting spikes this year with my Black Diamond. I have been archery hunting 15 years it will be  hard to switch but here we go. I will stay archery deer. Love that eastern washington late deer. This is what i used... 110 grns. loose powder 300 grn. hornaby low drag. 100 yrds. bulls eye and 3 shots within a inch of the bulls. very happy. I have read about the peep on the back but with that shooting i wont change a thing. At least tell i get a little older, Maybe. Thanks everyone for your advice on this subject.  Come on Peaches Big Bull Tag
