I know what you mean about ricochets, but they dont happen often enough for me to ditch the rifle.
once had one bounce of wet grass!
I tried the segmented CCI, didnt see much difference. have been trying for years to find a jacketed/hollow point or frangible subsonic round for the 22lr.
noise is a problem with the HMR, especially where I shoot. In an open field you wont hear as much being the shooter but everyone else will.
I use a PES overbarrell moderator designed for 22CF on all four of my rimfire calibres.
The WMR is the noisiest of them all by far, regardless of round. may as well be 223!
the HMR comes next but some way lower
the M2 is a cracking round, considerably cheaper than the HMR, still laser like trajectory out to 100, where it falls off is the next 50 -100 yards that the HMR has the advantage. just walk a bit closer!
the .22 is always going to be the stealth round of choice when dusk bunny bashing though. I tried CBLongs for short range stuff but mostly use Winsubs as they are quieter than RWS and Eley.
all I hear is a firing pin strike, the faintest of claps and the bullet strike.
I find the winchester subs are a bit softer and seem to ricochet less (difficult to tell the quantitative factor unless replicating the exact same shot though!)
I had a fox problem in my garden and was loathed to use anything that had ANY chance of a ricochet. I drilled into a winchester hollow point with a 2mm drill bit and forced in two no.6 shotgun pellets.
bit Heath Robinson but I tested them out on a turnip at 40 feet and they worked very well. mushroomed like a proper jacketed bullet and did not retain any energy on the other side.
I shot two foxes at about 25-30 feet. here is one I retrieved from the other side of the fox, it was visible in the hole it had created in the grass, had gone in less than 1". not really feasible for lots of shooting though!
