Picked up these 2 for $300 and couldn’t be happier. The R7 .20 cal.is a newer one and the 400 holds and works perfectly. I am very happy with both.
That's not to bad ! My .177cal is in that same energy range.May well no longer be but was once upon a time...lol. Mine is a 2005 built Huntington Beach version:
-H&N FTT's: Average 554, ES 11, SD 3, 7.78 fpe
-JSB Exact: Average 497, ES 20, SD 6, 7.53 fpe

Wow ! I didn't know the R7 was available in 5mm ! Seems a little under springed
for that caliber
