As stated what would be your caliber of choice for a FAC / fullpower HW90? .22 or .25?
"only going to be 18ft lbs maximum"..22 for sure,as it’s only going to be 18 ft lbs maximum and you can use pellets up to 24 grains if you want .25 weights,or better at about 16-18 grains 670-700 fps.
19.5 - 20.5 ft lbs seems to be the sweet spot as previously mentioned my one is at 20ft lbs with a 14.66 grn FTT and has the same manners as a sub 12.I bought a new .22 HW90 from AOA 6/23. I was surprised to find that ram set at 18.2b as my first HW90 (5/19; .177) was set at more than 24b and a ba$tid to cock and tooth shaking to shoot. (This was just before much needed, shoulder reconstruction and was nearly unusable.)
The .22 runs 19.5fpe and 20.5fpe with a variety of pellets and is a piece of cake to use. I never messed with that ram. They got it right for me. Maybe if my shoulder was better, I would jack it up.
I don't know if Weihrauch is systematically setting rams lower on the FAC or if it was the luck of the draw.
