I was prepared to purchase some Double Tap 125gr JHP for my M&P40c with Storm Lake .357 Sig barrel (a caliber I don't plan to load for in the near future). I am looking for a speedy load for hiking with the family and would like to put this Storm Lake barrel to use.
As always, I did some precursory research on the item as I usually do before placing an order.
I found some disturbing reports of chronograph results from consumers that were nearly 200 fps below the advertised velocities in some cases. Some additional research lead me to a series of YouTube videos from a fellow that goes by the name "drsjr1969" who fires various 10mm loads through his G20 and videos the chronograph results shot for shot.
He tests several loads and just about all are shooting slower than advertised, though what really concerns me is that the Double Tap box indicates the velocities listed are from a 4.6" barrel. Isn't that the same length as a G20?
155gr JHP Double Tap ammunition that was advertised on the box as having 1475 FPS from a Glock 20 actually yielded 1282 FPS from this pistol, while the 165gr DT Golden Saber load was listed as 1425 FPS from the G20 was actually chrono'ed at 1240 FPS.
So, I continued shopping and found Buffalo Bore also offers a "Heavy, low flash" .357 Sig load listing a 125gr JHP at 1450 FPS.
This drsjr1969 also tested Buffalo Bore and the 10mm he tested of their was advertised as a 180gr JHP at 1350 FPS and the actual velocity he recorded averaged out (from 5 rounds) to 1327 FPS.
I now plan on purchasing my .357 Sig "trail/hiking" ammunition from Buffalo Bore.
Here's my question: Are the substantial discrepancies in advertised and actual velocities a known issue with Double Tap or is there something else going on here?
Here's the link to one of the videos I am referring to, though he has many others: Sending various 10mm loads over chrono
