	This may be difficult to answer but with a 40-65 Hi Wall copy assuming it has a quality barrel, and using cast lead bullets and black powder what sort of groups at 100 would be considered very good for a five shot group an a good day ?. Mike.

	I don't know but a friend shot a 250, 200 yard ASSRA score target with his using smokeless. That also requires that 10 consecutive shots also have to have half the bullet diameters into the 11/2 inch 25 ring. So it would probably equate to 3/4 of an inch at 100 yards shooting off the bench and it would also probably being the Max.

	1 1/2" @ 100yds would be very good. Smaller than that would extremely good.

	At 100 yds, 1 MOA ( 1”) with a vernier sight is a very good 5 shot group and is obtainable

	John Boy, what load would you be using? Black powder or smokeless?

	If you need more than one shot, you need more practice!

	Thanks for that Jeff, I think J Lewis missed the bit about black powder being the powder used. Perhaps I should quit experimenting as I'm getting groups around the 1.1/4 " area now and was worried that I was doing something wrong, or I was just a lousy shot at 80 yo. Mike.

Mike. Mike, Here are some ladder loads I worked up for my .40-65 when I got it The .40-65 is a great caliber with great potentials for accuracy. The wind was really not too friendly the day I shot these test loads but I was sort of protected shooting along side of the berm. The range was 200 yards. The bullets used were paper patch and the load information is on the paper. LP

	Primary limiting factors are shape of the stock, weight, & sights. Then there is shooters bench rest ability, handling the gun & reading conditions. Black powder has little to do with accuracy compared to smokeless. Boats

	With black powder the fouling control method is as important as any other consideration. None of the aforementioned loads mention their means; blow tube, patches, bore pigs, etc. A book can and possible has been written on the subject. For my money a black powder load in any caliber over .38 is much easier to obtain top accuracy than with smokeless. If otherwise please feel free to pass any of your smokeless loads for a 40-65 my way, I need all the help I can get.

	Concerning what accuracy might be possible with blackpowder here are some results that I obtained recently at 200 yds. This was off the bench with a 20x scope. One group is of a 410 gr Saeco bullet and the second is a 429 gr custom bullet design. I've heard that the muzzle-velocity standard deviation for blackpowder can be lower than that of smokeless powders (meaning lower vertical spread).

And most "think" I'm shooting BP Mike.
