For some time I had fussed around with the idea of a direct replacement for 22 LR . I got serious about it with an NOE discount about 2 yr ago .
For what it's worth 225-37 PB isn't the answer in 222 or 223 . Well maybe if you felt like 1 gr of Red Dot would light reliably .
I instead went with the 225-55@62gr . I didn't shoot paper groups but it was satisfying to ding 4" steel gongs on demand with a 1180 fps load that makes about the same noise as the hammer fall .
I ended with with SPP and 3.0 Unique in the 223 .
Very quiet , no ear gear , and most certainly would wreck anything you might want to shoot with a 22 rf . It was still subsonic at 4,000 I expect it'll be super down here and need to back it down to about 2.7 .
I have also a 7×6.8SPC a straight neck up a whopping .007.
There was a surge subsonic everything and the 6.8 was not an exception to that . The 9.5 twist in the 7mm barrel allowed much heavier bullets than the 10 or 11 twists . The RCBS 7mm-168 SIL or at least my example is far too small on the nose . The NOE 285-150 FP (Hunter) worked much better .
I chose RP brass and WLRP for this combo because I have both this and a 6.8SPCII the LRP helps separate brass using FC SRP in the 6.8 .
I was surprised when I started down from 5.0 gr of Unique that the 154 gr bullet would be over 1500 fps . I was also surprised that half grain steps o slowed it by 100 fps . At 3.0 it dropped from 1150 at 3.5 to just 980 fps . 75 yd golf balls are fun .
Also quiet from a 21" target crown barreled Carcano .
Keep in mind that I don't shoot much off the bench and nearly everything is field positions and general body support posses .
This would be a lot more satisfying if I had an 80 gr 22 and a 175+ 7mm bullet , but it works , the loads are quiet , and nearly recoil free .
