Heavy pellets with break barrel

[true2hart]

I have a hatsan 125 springer .22 cal and wanted to buy 30gr pellets. Is this rifle powerful enough and what speed can I expect?

It shoots 18gr at about 875 fps.

Quick and dirty figure shows 677 fps with 30g, assuming internal ballistic unchanged.

Will firing heavy pellets like that cause premature wear on the spring/gas ram ?

I constantly get around 770 fps with a H&N Baracuda Match .22 Cal, 21.14 Grains, Round Nose. My ram is adjusted to 165bar. Buy the .25 if you want to shoot 30 grain. 

Sure your gun will shoot them but only in the mid 600's and your accuracy over 30 yards will suffer. 

770fps with 21.14 grain gets you about 27 +fpe. 

My 125 shoots 18 grains a little hotter, because the ram is not stock 150bar. They dont seem to be a accurate as the 21.14 but every gun is different when your talking spingers.
