I heard that the valve of the Raw hm1000x in .35 is larger than in .30 or smaller calibers

But I could not find any info confirming or providing this wrong.

People that told me this, heard this from others and that's how it goes.

The reason why I want to know is that I have a Raw in .25 with a barrel kit in .22 and .30 and I have the possibility to buy a .35 barrel kit. If it needs a bigger valve its not for me but if with the normal valve a output of 150 joule is possible than its something to have.

Regardless ...the projectile would still have the trajectory of a rainbow in .35 .....it needs a bit of powder behind it not air ....I don't consider .30 a small calibre being 40 / 50 grain specially if slugs are involved , as for finding any info on raw stuff I have looked but it's like searching for the grail

Indeed that is why I want a power of about minimum about 150 joule in .35 that should be around 240m/s and that is suffient for me. One needs air to generate this power and standard raw valve soms to be at the max with the .30 at 105 joules.

Acc the specs the Raw HM1000x delivery 170 joules in .35

Would like to know how the .35 get to that power, different valve or higher pressures and stronger hamer springs.

If I remember correctly from an article, may have been on Airgun nation- the 357/9mm block has a larger magazine slot than the other calibres.

Sorry I don't know the valve and port are larger too
looking at the slot, it appears to be cut further forward, perhaps the valve position is slightly different too?

Certainly does I've a 357 raw mag / probe and the mag is significantly wider

Massive plenum,..thats how the RAW makes big power. Look at all the benchrest competition RAW;s over last few years,..all have big inline plenums
