Each size shot showed about the same improvement smo.
Powder
Hard or Nitro card
Shot
Thin overshot card
Lubed full cushion wad
I want to list the load again so all will remember that I use a thin overshot card below the cushion wad. So, it's in front of the shot load doing its thing, whatever that may be.
I came to this load in stages.
In searching for denser patterns better suited to farther targets (grey squirrel comes to mind), and stationary small targets (squirrel again as well as turkey noggins), this load evolved over time. Spence will remember my groaning about how tall our hickory trees are here....the squirrels look like gnats at those elevations! :haha:
My guns shot poor patterns (think donuts) for stationary targets with the customary cushion wad under the shot. So, I tried loads without them using only nitro or thick cards over the powder. I saw improvement.
Our late member, Paul V, suggested I try lubing the bore after loading, in a turkey load discussion. I tried it. I saw improvement. The load now lubes the bore when the cushion wad is seated.
Next, I experimented with replacing the thin overshot card with heavier "over the powder" cards, then "nitro" cards. For awhile I settled on using two "nitro" cards on top of the shot load. I saw improvement.
I next looked for good performance with the benefit of a cleaner bore while rabbit and squirrel hunting where multiple shots called for my cleaning the bore afield with the non lubed load. The full lubed cushion wad on top of the shot charge came next. I lubed them heavier and heavier. I saw improvement.
The latest change I've made is adding a thin overshot card under the full cushion wad on top of the shot. My thinking was they may prevent a few pellets from driving into the wet cushion wad upon firing. Again, I saw improvement.
So, it's not JUST the "out of place" cushion wad making denser patterns in the load. It, along with the other ingredients of the recipe all work together.
I won't debate the science at work making the load shine. I'm just happy to use it in my hunting and hopefully pass along that which works for me to the benefit of others. :thumbsup:
