I'm supprised that it's made of phenolic resin. In general phenolic is a good product, very stabile, with excellent insulation propertys and high flame resistance.

My problem is that using it at the bench, to make case mouth wads, any little breeze, blows it off the bench. As a one case shooter, it's very frustrating. Any suggestions?

It's cheap (me too ) and I have used my radial arm saw to cut it and I don't worry about the waste.

Similar improvement in results to what my friend reports using 17gr of 4227 pushing his breech-seated 325gr Brooks 'Money' style bullet with reduced first driving band and Rem primer. He is shooting a C. Sharps Hepburn with a 28" barrel and 15" twist. His plan is to do some 200yd 'cast bullet' competitions with it this winter (any rifle, any sights - must be a cast bullet) and Schuetzen with it next season. The longer, heavier bullet should be an advantage at the longer distances.

DW is right
I still remember one of the funniest things I ever saw at a range was a guy and his Martini. This guy shows at the range with a military Martini in 577-450. He had 20 cases that he had topped with a Lyman 450 hard cast bullet he bought at the gun show. Well we called the line hot and everyone got busy shooting all of a sudden I here this whoomff and a ball of flame flies about 50 yards downrange. Well that got our attention. Sure enough its coming out of the muzzle of the Martini. When we could finally catch our breath from laughing we asked his load. Green Dot and a wad of toilet paper to keep in the bottom of the case was the reply. Well apparently there wasn’t enough Green Dot to get up enough pressure to get it to the 100-yard line but enough heat to light the toilet paper wad. 
  He finally got on paper but needless to say the accuracy was horrible. We gave him some better powder choices and a rough place to start. Then we called a cease-fire and went down range to put out the small grass fires.

I can remember some hot dry days helping to judge/control/monitor/evaluate M-60 machinegun competition - every 5th round a tracer.  LOTS of fires.

ITs been a while since I read that section so I may not have it totally accurate and would appreciate any further corrections.

It appears that there were problems "ringing" barrels when using over powder wads. Guys were using smaller charges of hotter modern powders and erratic powder position in the case was creating unpredictable variables.  Wads to hold the powder back were used to make ignition and burn more uniform.   Charlie spent a lot of time and several barrels trying to understand the reason and find a remedy. I don;t remember the exact cause mechanism; but his conclusion was that seating over powder wads directly in contact with the powder was a cause.  Seating the over powder wad a very small distance above the powder (with the charged case held in a vertical position) seems to have solved that problem.
Now remember that this may have been with older original barrels of less than modern alloy and heat treatment.  Was I am assuming with the larger target cartridges, basically the 32-40 and 38-55s, and it was done with the powders available at the time he was doing the research.
Todays situation may be different more and perhaps less position-sensitive powders and better grades of barrel steel.  However when I shoot old large capacity old BP large capacity cases with modern low vol/high energy powders, in my case 45-70, 38-55 and a couple european cartridges I still follow Charlie's recommendations

Thank you. Think I will keep the wads next to the bullet. Even small spacing from the powder is scary.  Sounds very much like short stroking a muzzle loader which will ring the barrel much quicker.
