to soot long range with a 40, you need a bullet 440 to 460 gns to keep up with a 45 with 540 gn bullets.
100 gns less bullwt wt = less recoil.
yes the odg liked the 40 for mid range, but their twists only allowed bullets of about 330 gns max.
this is where to 40/72 shines.
it works well mid and a long range for sil and targets.
you just have to do the homework on loading it.
brent and don, we will just have to agree to disagree on this one
as the French say, "vive la difference"
keep safe,
bruce.

It got lucky a few times but I'd not say much more than that. :)

I think I will chop off 4" on the #1 40-70 Shiloh and get it down to Silhouette weight. I used to shoot that rifle a lot for the gong shoots and it shot well at long range, but with the 16 ROT using the long nosed pointed bullets the rifle accuracy did not impress me at all. GG or PP.
But if I use a bullet with the blunter nose like a postell or even the blunter nosed Brooks Creedmoor this rifle will shoot well using a 420 gr postell nosed GG or PP bullet out to 1100 yards on the Shiloh range and the 1K Alliance Nebraska range even in the unpredictable winds on that range. I might be making a mistake taking 4" off that 34" barrel but maybe I will shoot it more for the silhouette games using the original Sharps round nosed PP bullet I have a adjustable mould for and I opened that mould to a 435 gr and it will hold the 1K target in fine shape.
The bullet profile has a lot to do holding stability when you start lengthening it.
My .50, I shoot a 1.5" bullet with it's 1/22 ROT and it does very good shooting that 718 gr torpedo. :D

I have a 40-72 with 1x13 twist silent match grade sstl barrel. My friend Marion Saltzman and another gent have our three guns smithed by Mike Lewis.

Unfortunately I have not been able to shoot it much after a heart attack.

Mine is on a browning 1885 hi wall action, I have 500 pcs Hornady brass and shoot the Paul Jones 430 money bullet.

If interested i would sell it
