I personally don't ever use more powder to fill a hull in order to get a crimp right on a shell. It is easier to use products on the shot column that will make a good filler. And I load on a progressive at a fairly high rate and most likely am not interested in inserting something like a cheerio in each hull. And I would not feel comfortable trying to extrapolate the possible pressure unless there is a load above what I am looking at.

I am also curious what Clyde liked about the Pro Reach. I have not been able to find any of it for sale or I would have bought some. Now that I look at the loads, I wonder why they do not show any 1200 fps loads. That velocity is pretty much my goal in the sub gauges with the exception of the 410.

I wonder how many rio hulls are needed before they will do some testing. I would be willing to bet we could get some donations on here to mail to them.

that may be a good question to ask them... if they need 50 or so that might be doable, and I know I have at least a dozen laying around here I could donate.

What I did a couple pages back was use the MEC bushing charts to help ID candidate powders that are with-in the range of published loads. In other-words, the bushing determines the volume needed with other components to get a good stackup so you don't need to monkey around with cherrios or overshot cards. Its about finding a "bulky" powder rather than adding more grains. Pro-Reach just wasn't a good match when looking at the data, but it doesn't mean its not perfectly acceptable in tapered hulls like WWAAs.

Yes, I was off topic, or Rio hulls.
I use and like ProReach because it is virtually perfect for AA HS hulls.
One of the lowest pressure, but highest velocity for that pressure, along with good fit.

Never got into hunting anyting larger than a few pheasents with the 28, but it looks like you guys are on to something with your specialized loads.
Not really into waterfowl, and between age and lack of wild pheasants today, it looks like that has virtually came to an end. (The 4 knee replacements complained a bunch during 4 days of real slim phesant hunting this year) The wobble skeet and trap fields are much less hard on them.

It's all good! The interesting thing is pro reach has a burn rate similar to blue dot, and bpi has published blue dot loads that use 21 to 22 grains... But I'm just not comfortable swapping powders based on that alone.... However that does seem like a candidate for testing, though economically, 22 grains of pro reach may cost more than 14 grains of unique or green dot.

mbedit, I understand your thought process now. I was jumping to a conclusion that you were not making. I will keep my eyes open for RIO 28 empties for testing.

Dave, pm sent with a contact phone #. I picked up 200 empty Herters 28 ga hulls for you yesterday. Made in Italy. And I got them at Luke. If you are busy, I will drop them off at the gun club in the office with your name on them.

Thanks much Chic! Good luck on the shoot at Avery!

Here is one on eBay:
