Day 3.5:

First accuracy tests held at short range. No reason to waste time/effort at long range with pellets that can't group well at short range.

So I normally weed out the "losers" at 20 yards, move the "winners" to double the distance (40 yards).  Then weed out the 40 yard "losers" and move on to 60 yards as time/ranges permit.

6 test pellets, two 5-shot groups each.  Knowing from pthe past test where the "sweet spot" was, stayed within that sweet spot for each test.

Test pellets:

Test (20 yard) target:

Rifle has not be resighted from the trigger parts swap above, so it's been out of the stock and partly disassembled...and off to the left.  But, it's always off to the left rather than here-n-there, which is a good sign.

At this point, trigger unadjusted, crown a little suspect, only 65-70 shots put down the barrel...I'm optimistic.

Certainly DID NOT shoot the pellets I expected it to shoot well.  I'd not have bet on EunJins or  a hollow point (and a hollow point that looks like a Phillips head screw) to "win" the short range tests.

Chronogrphed the two "winners".

The light 19.1gr.  managed to average 1019fps/44 foot pounds.  That's probably a clue to why the  lighter weight pellets (even though many think of 16 and 18gr. .22  pellets as heavy weights).

The heavy EunJin 28.5gr. pellets averaged  894fps / 50.6 foot pounds.

Your results surprise me as well. Seeing the Eun Jins shoot well makes me happy though.  They are absolute hammers on small game, even in the "little" 16 grain .177.  However, everything I own shoots H&N Sniper Magnums far more accurately, and in .177, there's only 1 grain difference...

My own experience with the Barracuda Magnums:  if something shoots them well, it shoots JSB Ultrashocks well.  This goes for my PP700W, the QB-79, and (despite being far underpowered) my 760 pumper.

If this one isn't a freak, then it's a +50 foot pound .22, with what may turn out to be (once broken in) good accuracy, and a decent trigger (using the spare part supplied) for $270.


On the "down side":

1. if you are a pump filler, will really need the power to put up with at least 4 pump strokes in for each shot out.
2. will need to put in the supplied trigger part, which will take about 30 min (or 45 in my case, as I spent 15min hunting up one of the little springs that got lost).
3. Have to like single shots (yeah...there have been repeater conversions...but unless you have a machine shop to do it yourself, if you "gotta have" a repeater,  the $ spend in a conversion would be better put to a rifle that is already a repeater).


Will swap the transfer port for the reduced one supplied and retest. NOT because I'm unhappy with it the way it is, but because I want to find out.

I'm looking forward to your reviews at longer distances and for you to get a good feel for the trigger. 
As far as having to pump a lot per shot.  I assume that would apply to any rifle that puts out 50 FPE in either .22 or .25?

my 25 cal mrod gen 1 was about 10 strokes of a benji pump per shot refilling from 2100.. so this is nothing
