Thank You very much for experimenting and letting us know what the results are, always good to know with the limited supply of powder and components . Thank You again and Good Shooting Chris

 

Looks like pretty darn uniform ballistics.

 

I was just wondering the other day what I was going to use for my 3/4 20 gauge loads after I run out of green dot. This looks very promising, thank you for sharing.

 

In looking down the barrel, was it pretty crappy looking between shots? Just curious.

 

I didn't check; the initial test loads were chrono'd out of a 391 (which cycled them FWIW).

 

Nice work, good idea.

 

Thank you very much for sharing. If ever I need to test a load, I'll also share. That sounds like a great load utilizing components currently available.

Fortunately (and unfortunately) for the past couple of years weird circumstances have curtailed my shooting to almost zero. Prior, I shot Clay's plenty regularly. And I will again going forward. Hence, I have an adequate supply of Green Dot and primers for now for my 3/4 oz. 20 bore loads. But when those run out, I'm saving your recipe. The data looks REAL good!

 

Thanks for sharing! I've been loading 3/4 loads with W572 for my 20, but I'm still dialing in the load, it's leaving the barrel dirtier than I'd like.

 

When you say 'dialing in your load' do you mean your working towards a good pattern on paper or do you mean how much dirt is left in the barrel?

The reason I ask is dirt in the barrel means nothing and is pushed out by the next shot.

What's important is the pattern you're throwing.

Increasing the velocity to get a higher pressure for a cleaner burn has the possibility of negatively impacting your pattern.

More velocity will open the center of your pattern and is perfect when the center is too dense and the outer portion is too thin on holes.

However, just like anything else in life, more is not always better.

Take a couple of shots at various velocities and see how the pattern looks at the distance you normally shoot.

Most clubs I belong to have a grease board that you can use and not have to be bothered with paper. Maybe your local club has one. Good luck!

 

Great to know this! Will have to share with fellow 20 gauge reloaders at my club.

 

Dirty loads don't bother me if the ballistics are ok. If you want clean you have to accept higher pressures. My 3/4oz 20's with Promo, Red Dot, Intl Clays are all very clean and all in the 11kpsi range.

 

Okay, that makes sense. I mean, I guess if I'm cleaning anyway... I try to stay low on the pressure, I'm assuming I'm in the 8kpsi range. But, I'm new to reloading, so I'm only staying low for safety reasons.

 

Thank you. I was going over my powder selections looking for a 20ga 3/4oz load with no results. The local gun shops had nothing that would work. I have plenty of Titegroup , hulls, wads, and primers. I will try a box or two.

 

Pardon my ignorance but what does SD 5 221 represent. I'm sure it's obvious
Thank you

Standard Deviation (SD, or Sigma) is a computational tool of statistical probability.

What the SD = 5 FPS means is that for velocity:
1) 68.27% of loads fired are predicted to fall within +/- 5 FPS (1 SD) of the average velocity.
2) 95.45% of loads fired are predicted to fall within +/- 10 FPS (2 SD's) of the average velocity.
3) 99.73% of loads fired are predicted to fall within +/- 15 FPS (3 SD's) of the average velocity.

What the SD = 221 PSI means is that for chamber pressure:
1) 68.27% of loads fired are predicted to fall within +/- 221 PSI (1 SD) of the average pressure.
2) 95.45% of loads fired are predicted to fall within +/- 442 PSI (2 SD's) of the average pressure.
3) 99.73% of loads fired are predicted to fall within +/- 663 PSI (3 SD's) of the average pressure.

 

SD=standard deviation with the numbers being for velocity and pressure

 

Thank you

 

Through unforeseen circumstances I wound up with 16# of Hodgdon titegroup, aka Highgun. Looking at 12g pressure data, the burn rate looks close to Green dot/International, so I made up a 3/4 oz. 20g load and sent it to Precision.
20g AA-HS
Cheddite 209
11.8 gr titegroup
CB 1075
3/4 oz lead
8 fold crimp

Velocity Pressure
1. 1205 9960
2. 1204 9690
3. 1199 9920
4. 1192 9440
5. 1195 9520
6. 1194 9520
Ave: 1198 9675
SD 5 221

Titegroup is very dense, so crimps will tend to be dished; this was mitigated with minimal wad pressure and deep pre-crimping.
Enjoy.

That's an amazingly uniform load you have there!

 

Pumpgun, if you haven't already done it this load is worthy of the 3/4 ounce 20 gauge Hall of Justice.

 

I wish somebody would try a 410 /with titegroup.

 

Too fast of a powder. There's a huge gap between 20ga 3/4oz and 410 1/2oz in hull volume and ability to contain all that gas. Interesting you want someone else to try wildcatting your whims.

 

410 powders need to be significantly slower burning than all the other guages>
..
They are in a class of their own and correlate well with heavy magnum pistol cartridges..

pumpgun,
Thanks for posting this load. Was this loaded using a MEC loader? If so, which bushing did you use to get a 11.8 grain drop? I would guesstimate an 11 which I would buy.

 

I used a #12 in a MEC 9000 with this particular lot of titegroup. Disclaimer: Always confirm charge weights with a scale. The pressures were well under SAAMI max, so if your setup throws a half grain or so more, I think you'll still be good to go.

 

In the end what I learned is that this might be a very good load, but no one has shot it very much. I just figured out that I am out of the 20ga 3/4 oz wads, I use the 7/8oz wad with Greendot, and I will have to wait a little to try it. Good loads will rise to the top in time, I very much hope this is one of them.

 

I have tried this load and quite impressed. My first 2 boxes were in a Briley tubed 625 Browning. Leads looked great and even broke a straight. My second day of shooting these were with an 1100 Sporting. I was interested to see if it would function and it did. Empties flew about 5-6 feet, with extremely light recoil. The barrel showed a fair amount of ash but didn't concern me. Thanks to the OP who came up with the load and had it tested.

I ran my initial test loads out of my AL391, and they all cycled, the empty cases lazily dribbling out of the action. This gun is somewhat sensitive to port pressures. With 3/4 oz, ~1200 fps it won't reliably cycle promo or green dot loads, but 20/28 runs near 100%.

 

I was getting 12.2 gr. With #12. 11.3 grains with #11. Loaded a bunch with 11.3 gr. To be shot in tubed gun. I am very pleased with the 11.3 gr. Load. Nice breaks. Very clean and economical.

 

Is your press single stage or progressive?

 

would you be able to substitute High Gun for Titegroup? I believe they are suppose to be the same powder

 

OK, I am going to give this load a try. So far, I have found that my brand new #12 bushing drops exactly 11.8 grains. I get great crimps with old style AA hulls as well as HS hulls. These light loads will run a Beretta 390 semi auto and eject with authority. Nice weather coming, I will report as soon a s I do some shooting.

 

I shot 2 rounds of skeet with these loads today. It was cold and windy, and I have not shot my skeet gun since August. I missed on 1 and 7 in the first round, no fault of the load. I missed a high 1 on the second and hit the rest. I was very encouraged with the performance on doubles. I shot a few pairs from station 4 when I was done, somehow had my timing and crushed every one of them. Nice, light recoil, good hits when my head was down. I would like to thank the OP for this load, it just might be a winner.

 

Single stage MECs tend to throw a tad more powder from a given bushing due to settling from the press being cycled 4x between powder drops, but in your case it's lot variations in the powder. That's why I check powder weights every time I open a new powder container of a different lot.
Glad to hear the load is working for you

 

I just loaded 200 of these 3/4 oz loads. I had not thought about it before, but with that little bushing in place, the powder seems to last a long time. I guess with the cost of powder today, an efficient load saves money. You do not have to stop and fill the powder bottle very often.
