In perusing my Accurate #1 loading manual I found under "32-40 winchester schuetzen" 

all loads are breech seated

No 9 12.6 gr 1332 19,600
1680 16.0     1395 11,300
2015BR 16.0  1151  5,000             very consistent P&V
2015BR  19.0 1348  6,000                          "

In burn rate 2015 seems similar to H322. 
Has any tried these? Those 2015 velocities seem low for schuetzen and probably need tweeking, but most loads do ....
Just curious. 
   

Having played with several powders over the years as well as the slow burning varities I have found few that will not shoot well when matched with the right primer for the powder being tried. The problem with most of the slower burning powders is three fold. One its takes more powder to accomplish the same velocity as a faster burning powder. Two most do not meter well even in the Harrel Schuetzen measure and three the price per pound can often times be quite a bit higher. There are also advantages to using a slower burning powder. There are now those that are not as tempreture sensitive, very easy to ignite unlike the ball powders, meter extremely well and burn real clean. A big advantage is the recoil is also softer and there is less rifle disturbance in the bags. I am curently working with such a powder in my 28-35SS and the accuracy potential has been extremely surprising as well as consistant. But I am also not ready or willing to let that Cat out of the bag yet as I still have alot of testing yet to do. But I would engourage others to pick one with with those same good qualities and to get out with it and to do the same.

What year is the Accurate reloading manual from?
Reason I ask is 2015BR powder has changed a few times thru the years. The best lot of 2015BR they sold was manufactured in Israel. Being that I use it in my jacketed bencrest rifles is why I have quite a stash of it.
I have been pondering trying it in the 32-40 and 33-40. It meters great in the Harrels and is a short kernel extruded powder.

I also wonder if Re7 might have some use in Schuetzen calibers?

John,
Thank you. Just wondering as I have found good results 
for Re7 in 38-55 CB loads. And have a good supply.
I may try it in my 32-40 Rem Hep. Which has a similar case capacity as the 30-30.
Seems like its in a favorable burning range. as is the 1680 you mention and the 2015 in this thread.

I have something that shoots very well and is always match ready I just enjoy the journey of possibly finding something that might be just a tad better. Been doing that for over sixteen years now and I still enjoy doing so. If one just keeps doing the same ole thing he only gets the same old results and will never find any possible improvements. That also holds true for bullet designs, primers, seating depth as well as powders. Once you have something established that really works well it can only get better from there and what I always strive for. As I never want to leave anything laying on the table for someone else to walk off with in a match when I have the same opportunity to do the same if possibly not more so.

296.  I recall it was one of the Olin (Win) ball powders for which the factory warned about reduced loads in ctges i was shooting at the time. the 44 mag for handgun Silhouette. 
  I imagine, ditto H110, which is said to be the same powder.

Thank you, Frank for the clarification on 296
