.735 Round Ball and H&R Ultra Slug Hunter

[leadhead 500]

I am using the Lyman .735 When I load them I always make sure to put the sprue up. Not sure of it maters or not but I am sure that if the sprue is loaded in different directions it will show on the targets

Sorry for need for clarification, you mean pointing at the sky up, i.e. 90 degrees from muzzle, or in line with muzzle? Pointing down range makes sense as it avoids the rifling. Up as in up in the hull up, right? I assumed you were using the Lyman mold, which is why I was asking about the sprue. They all have a proud sprue.
Thanks

I wish I could find some steel powder around here.I have almost shot up all of my blue dot and the long shot is starting to get hard to come by. My .735 round balls weigh around 585 grains with the lead mix that I have in the pot now

[leadhead 500]

I load them so the sprue is pointed to the sky

Interesting. Thanks. No more from me, as I have doubled your post count.

LH, these folks have Steel, on sale no less! Another member put me on this last week and I bought some, but have not received yet. Musta shipped by wagon train. I haven't found Longshot in a year...585 grns, man that's gonna hurt.

Nice results indeed leadhead. I will have to work on those round ball loads after I get the 525 slugs tamed.

interesting: you inverted the aa12 gas seal.

Can you expand on that? what made you try that? how did you modify it (cut petals, etc) to get it to work for your purpose?
what does it look like after being fired?

why over the hard card instead of under it?

Interested!

IMO that is impressive. I did a search and have seen pretty good results from the big balls in shotguns. One of a CB threads from back in 2008 showed 2 to 3" groups @ 100 yds with a screw in rifled choke tube. I have heard of it being easier to get accuracy from than the Lee 1 oz. I have thought about using it where the shots cannot go past 100 yds. I was just thinking if that ball would kill a deer though. One of my main concerns when getting to the hundred mark is a November 10 to 15 mph crosswind with gust up and possibly pass 20 mph with the speeds usually used with that bowling ball. With just fluctuating 5 to 10 mph winds that ball can move around a bit opening up groups that would be otherwise very exceptional. The wind flags would have to come out almost in the hunting blind @ 100 yds. I think maybe why it does so well and other big balls is regardless if the wad column cants at ignition and down the barrel is that there is only one point basically on the bottom of the ball that is generally centered instead of the bottom rim of a slug. Here is a little data on ballistics of a 73 cal ball @ 1400 fps. I have an 835 with catilever barrel so the scope height is a little higher providing a seemingly flatter trajectory. I don't think you would have to worry about TOF though, nothing like jumping a ball like jumping the string.

The gas seal is cut off of a Winchester AA 12 was and is turned over sitting on top of the hard card was making a cup for the ball to set into. After firing them they are in great shape almost look like they could be used again

thx.
And great groups, so 'well done'.

This thread gives me the heebie-jeebies! GOOD heebie-jeebies! There is actually hope for me then. I will be testing my .735 round balls out of a Rifled Mossberg barrel by end-January. I look forward to even a 2 or 3 - inch group at 50 yards.

If I had a rifled gun my choice for slug would be either (or maybe both) 0.735" round ball or Paradox style slug. However, in your case the Paradox style slugs usually run around 750 grs. +/- so difficult to accommodate just replacing payload in factory shells.

I was seriously thinking about getting a rifled gun but now that I am out of work that won't be happening, at least until I am working again.

Should I get the rifled gun, my 0.735" RB mould will be steadily employed.

The shooting I did with 0.735" RB's in my smoothbores and the one round of testing in rifled gun were with range scrap alloy of about COWW hardness and unlubricated. I got no leading at all in either the smoothbores or rifled gun. However, I think for steady use in a rifled gun I would tumble lube the balls or use a felt wad soaked in softish lube under the ball to ensure there was some lubrication getting to the bore.

I will be following with interest to see your results. Certainly leadhead 500 has his load and gun dialed in with the 0.735" RB's.

Personally I think the 0.735" RB is an obvious choice for slug and I am surprised more people don't use them.

Good luck and keep us posted. I have enjoyed following your quest for accuracy with your shotguns.

Greetings, What a treat for 12 ga full-bore .735 RB lovers.
Leadhead 500 thanks for sharing it.
I'm sure our visiting friends would like that.
* * * I wanted to give it a Good rating but could not as the Star Ratings need to be changed to 3 Stars as Good.
