Power block or not?
- Thread starter Rodmar
- Start date
if you buy an impact m3,
it will already have the powerblock/power plenum in it.
slugs are a long long lonely road,
more times than not it ends with frustration and a return to pellets.
your mileage may vary,but be warned lol

If you want the you the most power out of your M3 possible then yes the power block is the way to go .
My .25 caliber 700mm M3 with P/B shoots a 46gr. H&N heavy slug 970fps. For 95+ ftlbs.
I have been shooting them through the new. 25 STX SLUG 1:16 liner with good accuracy.

Thank you, I two years old M3 so no power block.
I have good results with pellets, just try to make sense changing to slugs or just getting a new Slug rifle!

For the MKII you get the power block and 720 Plenum as a set in the upgrade kit at Utah Airguns.

Just port out your old block threw the set screw hole there really isn't a whole lot of difference between the the two if you really want to up the power add the 720 port out your old block and add another power plenum where the back gauge goes I was shooting 56 gr pellets out of 600 mm at 920 fps at 160bar with tungsten hammer weight

In the block it holds the valve into the block u have to open the hole side to side not front back so the orings still seal the hole for transfer port I used a Dremel and was able to open the sides of the valve and the port in the block so it's closer to the double port size in the barrel also I used a tungsten hammer and a setting of a 160 bar used the valve adjuster up front to limit it travel just little bit just under 4 lines on the valve adjuster

Just an idea...
Try your current M3 in a configuration (tune) you hope for slugs and document your progress. If it meets your requirements, great!. If not, move on to a PP. Retune and document as well.
I would suggest testing equal weight slugs, or, lighter than your current pellets. Not heavier for sure.
Keep us posted on you journey.
