Shot Card (Veggie Wad) vs MMP Sub-bridge

[sabotloader]

Returned to Popes farm this morning to run a quick test.

I wanted to compare the velocities I would get with the Lehigh 50x325 shooting the bullet with a card and/or with a Sub-Base. The picture below shows the Circle Fly Shot Cards (Veggie Wads) that I use and a few of the MMP Ballistic Sub-Bases or Sub Bridge.



Today I set up the chrono and decided to shoot only T7-2f with a #11 Mag cap comparing the two velocities. The same projectile was used Lehigh/Bloodline .50x 325:

t7-2f ----------- t7-2f ---------------t7-2f ------------ t7-2f
110 grain ------ 110 grain----------120 grain-------120 grain
Sub-Base------- Shot Card----------Sub Base-------Shot Card

1. 1762----------1. 1790------------1. 1884---------1. 1879
2. 1765----------2. 1780------------2. 1883---------2. 1856
3. 1760----------3. 1775------------3. 1884---------3. 1878

Really can not say that I proved anything at all other putting a few bullets down range - which is always fun...

That tells me the MMP sub bases likes more pressure and then it will preform better , The shot cards are more constant , tho

Mike did you notice any difference in accuracy

no - not really any at all - I ended up with two large ragged holes in the target.
