.50-70 range time
« on: November 03, 2020, 02:26:06 PM »
Took the Shiloh out to the farm today for some sight work.  Very basic loading, the Accurate 51-630r, 20-1 lead-tin, over 68 grains OE 2f, WLR primer, Starline case.  No wads.  Unsized,  Beeswax/olive oil lube.  Seated over cross sticks.  30" barrel, 1/22 twist.

Recoil: Not bad at all.  Rifle is 11.5 lbs, velocity around 1100 fps.   Shot some 450 goverment loads to warm up/foul, did not seem a whole lot different.  Maybe prone . . .

Initial sight setting (MVA 108) was 25. 100 yard group under 3", 6" low.  Raised to 30, same group, dead on. (Yay!)  Extrapolating from the charts in back of "Black Powder Reloading Primer" Garbe & Venturino,  200 yard setting should hit 15" high over the 100 yard group.  Dialed the sight up to 40.  Same hold, next group 15" higher. 

Now I did not load a lot of rounds, thought I'd spend them figuring out the 100 yard setting.  It was a lazy afternoon, walking back and forth to the 100 yard target.  But all this went a lot easier than I thought it would.  Had 1 round left.  My brother had cleared a lane and hung an AR500 66% ipsc silhouette out at 200 yards the day before.  Leaving the sight set on 40, sighted on it and touched off the last round. A nice solid hit, target and stand fell over.  Another nice walk out to reset it.  I suppose the .50 hits harder than his .223s.

Damn, but the .50-70 is just easy to work with.  Need to cast a LOT more of these big bullets.

I'm not familiar with that bullet but the name seems to imply it is a 630g projectile. Is that right? Seems a little heavy for a 50-70. But then, all my past experience was through a NY Militia Rolling Block and I shot the 425g Lyman bullet over a heavily compressed 65g of FFg GOEX. This was some 25-30 years ago. (smile)

It's heavy all right, but works well in the .50-70 if you've got a fast twist, heavy rifle, and want to go past 200 yards.  Don't shoot it in a carbine!  If you ever want to shoot BPCR Silhouette you need something like this for the .50s, the 450 is way too wind sensitive.  And yes, it also helps to be crazy enough to want to shoot a .50 to begin with! ::)

Was sure a nice day for it. Been too busy working on the new house for any shooting here. :(

Drydock,

I asked because I recently purchased a used Shiloh Business Rifle in 50-90 2-1/2" Sharps Straight. One source lists the original factory load being either a "473g greased" bullet or a "540g paper patch". Your 630g seemed outside thoseperameters, hence the question.

With my aging eyesight and disabled condition I'll never shoot beyond 200 yards if that much. I just want to know what it was like to shoot a Big Fifty buffalo rifle.

Oh yes, historically the 50s were loaded with relatively light bullets,  and never seen as Target Cartridges.  Buffalo were usually shot between 100-200 yards.  I'm definatly outside the original parameters, but I've got my Chiappa Carbine for that.  Although the rifle does shoot the goverment load very well.

Your rifle probably has the 1/36 twist, and will love the goverment weight bullets.  Have fun!   ;D

When I called Shiloh to ask about the groove diameter (I have since measured it) and twist they said all their 50 calibers have always been 1-22". That's why I never considered the Lyman 425g design and have found a 480g from BACO that's close to the 473 original, if they ever get them back in stock. My reconstructed right shoulder is begging me not to go to anything over 500g even though I have a Magnum shooting pad to wear. LOL

I think I was told that my Shiloh 50-70 carbine had a 1x26" twist. Stabilizes even heavy bullets.

Much more pleasant to shoot with 375 and 450 gr bullets!

Check the twist just to be sure.  While the standard twist is 1/22,  they do offer the 1/36 on request, and many do request it.

Back out to the farm again.  Wanted to shoot up some of my government loads to free up more brass for the big bullets.  A pleasant surprise to me is that the 450s shoot to the same sight settings as the 630s, at least out to 200 yards.  Nice tight groups on steel at both ranges.  The 1/22 twist seems to shoot the lighter bullet just fine.  Need to break out the chainsaw and brush hog and see if we can get back to 300 yards before we get to the bluff back there.

Spent some time out at Jerrys farm (where we hold the GAF Grand Muster) in Nebraska.  He has an excellent long range set up out there.  I shot both my 450 grain Government loads and my 630 long rangers.  Found  that the 450s work great out to 300 yards, but get very wind sensitive past that.  I used the MVA "B" scope out to 400 yards until it ran out of elevation.  Hits with it on the rifle were stupid easy!  Past that I put on an MVA mid range Vernier.

While the 450 was wind sensitive, the 630 seemed to barely notice, and really hammered the 400 yard target.  I then started walking it out to the 600 yard steel.  Took 4 shots to find the range, but that final clang felt dang good.  Good line the whole way, just kept adding elevation.  I hope to get out to 800 some day, it looks like I've got plenty enough elevation left on the staff to do it with this load.  Need to get a higher rear sight block for the scope too.

One of these days I want to go to the "Q".  Something for the retirement bucket list.

You're basically on the way, I'll stop by and pick you up.  (someday)  Its the weekend before the GM weekend.  Pretty much looking at a two week shooting  holiday.  You need a spotter for the Quigley so you would be useful . . .
