Benjamin 392
« on: June 30, 2007, 02:58:00 PM »
I have just received my Steroid/Billet 392 from Tim at Mac 1 and couldn't be happier.  His work on the pump makes it so smooth.  He does also have service after the sale.  I am getting great groups with the Williams peep.  I can't wait to see the chipmunks back in the yard.

I have been thinking about getting a totally juiced-up MAC-1 392.  I read on the MAC-1 site about the 14 (14!) pumps but could not find any velocity numbers.  How fast is yours?

I do not have a chronograph, so I am not sure.  I have read that others are getting around 620 or so with 6 pumps, which is about what a 392 should be stock with 8.
Good luck pumping 14 times.  I think 10 is about the most I can get without working too hard.  I am getting good results with 4 to 6 pumps.
