Well , revisiting this thread....with an update
I dragged my heels on a purchase for a while, looked at models & brands ad nauseam....
In that time, one company - "Shooting Chrony" has apparently ceased to manufacture....
They are still in stock for sale it appears , but the company is shuttered from what I read.
The price ranges were $80 for the Caldwell - to the LabRadar Doppler Chronograph @ $559.99
I looked into the MagnetoSpeed barrel mount @ just under $200 and the Competition Electronics ProChrono about $125
and another brand north of $500 price, for the Oehler 35P
In the end, I was just way over thinking it... I tend to do that
sometimes.
So I finally bought a Caldwell ( base model ) I skipped the deluxe kit ( I don't need the indoor light kit or the tripod [ already having a camera tripod ] )
It is the best bang for the buck ... IMHO I used a 10% coupon and free shipping , for total of $ 76.60
So far I have dialed in my TB/260 grain HB bullets , Webley hand loads.
