	I'm looking for info on what smokeless powder is ok to use and how much. What size bullets to use for shooting 1000 yards. I got the gun from a friend who never shot it , he says it's a 1879 hepburn 40 72 hi wall , rolling block with a single trigger . Thanks

	Russ, Your choice of bullets will depend on What is your barrel twist, land and groove dia,etc? For reference: My 12 twist 40-72 stabilizes my BFSS 460 gr ,1.55" long GG bullet, as well as my 440 gr 1.54" Elliptical PP bullet out to 1000yds. beltfed/arnie

	My barrel twist is 22 . I thought a 320 gr. Bullet might work. Thanks for your input

	Is a hepburn high wall rolling block anything like a SAA Colt with a 4 inch barrel and ejector?

	RCBS Makes a couple of .40 caliber molds that might work, but need to know your bore size first. Slug the bore to see what size bullet is needed. The two RCBS .410" are the "40-350-SP-CSA" and the "40-300-SP-CSA" Both would be good choices for the slower 22" twist your gun has. I use the 350 in my .40-70 SS Hepburn with 20 grs. of 2400, but my twist rate is faster than yours at 1:16".

	Russ, seems to me the original bullet for the 40-72 was about 265 gr and the rifles were generally a slow twist like your 1-22 . But, an appropriate dia. 320 gr bullet will probably do ok at least to modest ranges You may find that Re7 or similar smokeless powders will work pretty well. Check the handbooks. You will find the Sharps 40-70 loads in the Lyman No 48 or later books will work since the 40-72 is the same, but only a 0.058" longer case. beltfed/arnie

	that is no 1000 yd target gun but rather a 100 to 200 yd hunting rifle . use it for what it is and enjoy it. if the chamber is still original you might nt be able to get rounds loaded with groove diameter bullets into it.

There is an 1879 Remington Hepburn No 3. There is an 1885 Winchester High Wall. And, there is a Remington Rolling Block. All different rifles. Can't help on the bullet as I only shoot BP in BP rifles.

	The original 40-72 barrels typically had a .406" groove diameter, I believe. More modern barrels are .408-.409". It will be important for your friend to slug the bore to determine which diameter to size his bullets for optimum performance.

The slow twist rate will make 1000 yd. shots pretty tough, if not impossible. But I wouldn't limit it to 200 yds. either. I've seen enough similar rifles shooting 500 yd. dingers with consistent hits.

	If it were my rifle I would try Arnie's (beltfed) 368gr 40cal bullet. If you are shooting that evil smokeless stuff you can load it up to 1500fps+ and may find it stabilizes at the faster velocity. With hard lead you may be able to get up to 1600-1700fps MV. Worth a try if going for 1000yd.

	Great gun, fun cartridge too!! Though I have both a 40-72 and a 40-82 both Winchester repeaters. All I can say is they are both based on Express loads meaning light bullets, faster speeds. These were made at the start of smokeless and end of black powder. Lighter bullets, I wouldn't go much over 300 grains and that too you may easily key hole at 50 to 100 yard. Mine both did key hole. I'm stuck with under 300 gr. Last I remember 265 and 280 shot well. Just my .02 worth If you can find a few of each before you buy a mold. Lastly chamber cast bore. Smokerless trail boss shoulf work well. I start with 70% case volume to BASE of bullet NOT 70 % full case. Call Hodgen to verify. This is what I do. Check what they recomend. Paul

	Thank you all for the info , I think with everything you have told me i can put together some shells that will work. It does take a 406 bullet and I'm going to use 320gr. Thanks aging.
