I am wondering whether any gunnutz have used the Canada Ammo D700 powder as a substitute for 700X in reloading 12 gauge target loads?
It should be OK, but I am hoping for feedback on this application for D700.
I usually load 17.2 grains of 700X for about 1200 fps for Sporting Clays.
 
I no longer load for shotgun but I printed this from Budget Shooter Supply website.

You cannot work up a load for shotgun without pressure testing. Use only cannister grade powder and published recipes. You can easily stray into proof load pressures with shotgun reloading.
There is no way to read pressure signs with shotshells like there is with metallic loading.

Thank you the spank.............I checked the site you referred to........That was really the only reference I have seen with respect to shotshell loads with D700.
 
Based on the little info available and looking back to an answer given in a thread in 2016 I would be very skeptical about using a powder that has no published load data due to it’s changing properties for each different lot!! In fact my personal option would be PASS!!
 
I have bought 800x and 700x.......to date,in my opinion, both are a bit hotter than if I used canister grade..I have concluded this by chronographing my regular powder loads and then load the D powders slightly shy and work up to the velocity of my canister loads.Is it exact.....no......but,is a noticeable change....yes.

I load for trap rounds,so there is already FPS restrictions and weight....shoot enough panzy loads and you can tell in a hurry if they are a bit stout...I have not loaded field loads yet with this method so I can not comment on the reaction of powder in larger/ heavier loads.I would like to try,but I ( in my best Elmer Fudd voice) would be very very careful...

Most modern day shotguns can handle a lot more pressure than grampa’s gun....just be careful and aware of what you are doing.
 
Shooting unknown overpressure loads in a shotgun is just plain foolish. Where, in any reloading reference, does anyone recommend that you shoot a steady diet of proof loads?

You have to think of what happens if the weak link, a shotgun cartridge case fails, as they have been known to do. I like my fingers and my eyesight, thanks.

Velocity does not measure pressure in shotgun loads.
 
You aren't telling us what other components are being used. Also you do realize their isn't a direct correlation between velocity and chamber pressure in shotshells? Without pressure testing, you have no way to tell if that load is pushing 14,000 psi.
 
There is a real difference between safe working load and tested to destruction. I will assure you that if you have a case head failure that you will be wearing pieces of the gun long before 55K psi.
SAAMI maximum pressure for 12 gauge 2 3/4 inch is 11,500 psi.
Ignore good loading practice at your peril. I like my fingers and eyes too much to play with some of you people.
 
Please, case head separation won't cause the gun to blow up. Did you even read the article? But, to your point, he did state:
Where excessive shotshell pressures generally occur is in improperly put together reloads. But these are generally mild excess pressure situations, not giantic ones involving double and triple charges of powder. However, keep in mind that mildly excessive reload pressures are continuously stressing the gun and contribute to high recoil levels. This in turn tends to eventually crack wood and begin to break little parts within the action and trigger group. So, it is never wise or safe – and nothing positive is ever accomplished – by firing modestly excessive pressure loads in any shotgun.

I will be sure to stand well to the side of young Mr Oops the next time I'm shooting trap with him and he's puking empties all over my pristine Perazzi. :d
 
What you are clearly not understanding is that case head failures in shotshells are not unheard of, and loose gas in an action has great destructive force.
Yes, it is rare. Not going to be me, however. Why a person would test their luck to save a penny or two a load is beyond me.
I am pretty sure that I have read everything that Tom Roster has written and published, along with all the other shotgun writers.
Repeated overpressure loads are not wise. Loading without reliable pressure data is not wise. Shotshells are very different than brass cartridge cases, and there are no overpressure signs for reloaders to observe.
I cannot do more than advise caution and only use published safe loading data.
I have seen blown up shotguns and rifles, and often the story is not at all clear. People, having blown up their gun, are frequently reluctant about revealing the truth.
 
Here is the load

Shot.....1 oz of home made 7.5/8 shot...it is just a touch heavier by 2-4 ish pellets

Wad......Gualandi BRG 25

Hull......a straight wall,low plastic base wad,brass head,I think they are cheddite hulls.These are on their final firing of 4 times

Powder.....17.5 grs of D700....I can not remember the lot number off hand

Primer......Cheddite primers

The gun used is a Remington 1100 competition synthetic.I use a long range Pattern master Anaconda choke..

Wad pressure is about 15-20 on the Mec Versamax....I do like to seat the wad on the powder firmly and considering I have a touch more pellets than the wad can hold , the extra room does allow for a very nice 8 point crimp.

This Powder really seems to burn cleaner than if I was to use the X powder....cleaner meaning less smoke and less residual carbon.if you shoot a 1100 with dirty powder on a cold day,you know in a big hurry!!....this D powder did work very well.

I give this info for those who may find it useful.......
 
This actually highlights the issue we are trying to point out to you. Using the Hodgdon 700-X data, that load should produce about 6700 psi which would burn extremely dirty, most shotshell loads won't begin to burn clean until they have reached over 9000 psi, around 10,000 is the sweet spot for an efficient load and clean burning load in most 12ga applications. If you are getting clean enough burns on that load to make a Remington 1100 happy, the D700 is burning hotter than you think it is.
