Any idea what the pressue is like on new Herters Target loads?

[B. Dudley]

Other than RST, who caters to the vintage gun/low pressure crowd, no ammunition manufacturer is going to tell you want the chamber pressures of a given load is.
They will only tell you that the loads are according to SAAMI spec. Which is a max pressure for a given gauge.
Likely because this leaves them open to the possibility of component changes which could change pressures along the way.

I once gave Federal a call in order to ask what the PSI was on their Estate Super Sport Competition loads in 1 1/8 oz. 1145 FPS. However, I did not receive any definitive answer. Just that they were right around 10,000 PSI. I seem to remember that Tom Roster in an article once said that there was no correlation between lower feet per second loads and low chamber pressure in modern loads. I agree whole heartedly that RST is the only manufacturer that really caters to the vintage shooter who definitively needs low PSI loads.

Exactly right on the fps and pressure correlation. Just look at reload data and you will see it is all over the map.

One thing to keep in mind when discussing the big ammo manufacturers is they must make there product with the auto loader in mind. If it does not have the pressure to operate those guns they lose a large segment of the market. So I assume the pressure is up there until proven other wise.

The pressures of the discontinued Herter's shells (I think by Cheddite) were surprisingly just below the SAAMI recommended max. of 11,500 psi; likely loaded with very fast burning powder.
As stated, only independent pressure testing can give the pressures of the new Herter's.

So Drew, if I'm reading that correctly it looks like between 1900 and WW1 they were shooting field and target loads generating pressures between 8,000 and 11,500 psi?

[Drew Hause]

That is correct John. But some fellas pushed the envelope a bit

Kansas City, Oct. 23 1897
A remarkable exhibition of live pigeon shooting was given at Exposition Park, this city, yesterday afternoon, when Fred Gilbert, of Spirit Lake, Ia., and J.A.R. Elliott, of this city, met in a match at 100 live birds for $100 a side and the DuPont trophy, which Elliott won from C.W. Budd a few weeks ago with the score of 99 out of 100. The match was for the DuPont trophy at 100 live birds each man, 30 yards rise. Gilbert and Elliott tied at 97, then Gilbert won 25 to 24 in the shoot-off.
Gilbert used an L.C. Smith hammerless gun, 3 3/4 drams DuPont smokeless powder, 1 1/4 oz. No. 7 chilled shot in Winchester Leader shells.
J.A.R. Elliott used a (7 1/2#) Winchester repeating shotgun, 3 1/2 drams “E.C.” powder, 1 1/4 No. 7 1/2 and 6 chilled shot; Leader shells, loaded by Winchester.

1 1/4 oz. 3 1/2 Dr. Eq. BULK Smokeless was about 11,500 psi; the modern SAAMI max. for 2 3/4" 12g
and 1 1/4 oz. 3 3/4 Dr. Eq. (1330 fps) in an 8# shotgun = 29 ft/lbs free recoil
1 1/8 oz. at 1200, (3 Dram) 7.5 # shotgun = 23 ft/lbs of free recoil

[Drew Hause]

Independent testing of Cheddite for Herters 16g “Select Field Dove and Quail” 1 oz. at 1165 fps showed pressure averaging 12,500 psi with one at 13,400 psi.

Gilbert was shooting a hot load! And it paid off.

I liked those herter 16 ga loads, and still have several cases of them, BUT, I will only shoot them in my NID 4E, Utica 16 Sterlingworth, and Fair Rizzini 16 guns.Then I happily cut them down to 2 1/2' and load low pressure 7/8 oz loads. I've given a bunch of hulls away, and still have close to 1000 that need cut down.
I'd be ok shooting them thru my steel barreled Parker 16's also for hunting, but not for the extended shooting of sporting clays--too much recoil for me, my O frame DHE 16 only weighs 6 LBS.
