Who/how do you all use to test load pressures? Are you able to just send a handful of loaded shells without much hassle?

I loaded several flats over the winter of 1oz GD loads and after reading all the concerns in recent posts I’m now hesitant to start shooting them…even though I’ve shot this load without issue for a while. Was thinking of sending in 20 or so from various batches…..

Thanks I’m advance for any information.

Here is Tom Armbrust's information, he will test the loads for you:

Tom Armbrust Ballistic Research 1108 W. May Ave McHenry, IL 60050-8918.
Ph #815.385.0037

or,

Here is the link for Precision Reloading LLC, they will also test the loads for you.

However what fn16ga said is true, buy another lot# of the same ammo and the game will probably change. If you are looking for chamber pressures below 8,000 PSI, I'd save my money. You'd have a better chance of finding a unicorn.

TripleH,

Send 5 shells from each different batch IF there is something different about each batch. If they all use the same components with the primers and powders having the same lot numbers, send 5 shells or 10 if that would make you feel more certain. Do not send less than 5 from each batch because the data is taken as averages and not individual shells.

The loads have to be sent thru UPS, FedEx or Speedee Delivery. The post office can't/won't deliver live ammunition. There are no extra fees for loaded ammunition. You will need this label for the outside of the box, which you can download online and print. It's approximately 4" x 4"

Thanks gents.

Believe the loads are the same aside from 1 grain of powder I went with in the rounds I loaded for clays vs. skeet.

I’ll send 5 of each. I’m not chasing 8,000 psi - just want to feel ok with them after recent reading on 1oz Green Dot loads….

Want to say it was 1oz, sg16 wad, ched primer, ched (old herters) hull, then 16.5 and 17.5 of Green Dot. I’d pulled it off the spreadsheets…

You will be fine with that load and 16.5 or 17.5 gr. of the new green lid green dot. Herters are Cheddite hulls.

Ched\Ched SG16-

The older green dot is ~ a full grain more to achieve the same results. The spreadsheets are most likely the older green dot and is obviously still valid with black lid green dot.

So black lid is the newer stuff, I had thought it was the other way around.

The printout I was using off the spreadsheets with those components listed pressure at like 8,400 with 18 grains with 1165 velocity so I think I bumped it up a tick to 18.5……which looks like it’s really close to no goodsville…..

TripleH,

With the variability of 1 oz. loads using Green Dot, I would send them in and see what happens. To me the color of the cap means little. The Green Dot debate started about 20 years ago with it's fitness for use in the small gauges for standard target loads. It started when folks were cracking Briley 20 gauge tube sets.

Most folks reload a little different then the next person, sometimes it means a little, sometimes it means a lot.

You will spend a lot of time disassembling loads, and destroy a lot of hulls and what if the loads you have are OK?

Weigh your options before deciding, without proof, that your loads are over MAP.

Thanks guys. I’ll be sending some of these in and will post results when I get them back.
