WOW!

Ok, I wrote up my initial experience with the 48 and sent it to Brad. He has it in his Airgun Reviews section. Here is an update to those musings.

Took the M48 and the Kodiak (both in .25) to the range today. Clear sky, light wind.

Both guns initially zeroed for 50 foot NRA silhouette. So that gives you an idea where the adjustable mounts are set.

So here's the breakdown:
Kodiak:
Stock Gun
BSquare one piece adjustable mount.
Bushnell Trophy 6-18x.

M48:
Stock Gun.
RWS one piece C-Mount
Bushnell Trophy 6-18x.

Re-set Zero for 30 yards on both, using only the scope adjustments (didn't move the mounts).

Set up cardboard, shotgun shells, 4"x4" steel plates with welded pipe on one side to act as a foot, plastic bottles.

Diana Domes used.

30 Yards.
Shot from sand bag:
M48 5-shot group covered by a quarter, shotgun shells sent flying, steel plate knocked over.

Kodiak 5-shot group covered by a quarter, shotgun shells sent flying, steel plate knocked over.

Shot offhand:
M48 plastered bottles.
Kodiak plastered bottles.

45 Yards.
Shot from sand bag:
M48 Same Zero: 5-shot group covered by a 2" circle, shotgun shells sent flying, steel plate knocked over.

Kodiak Same Zero: 5-shot group covered by a 2" circle, shotgun shells sent flying, steel plate knocked over.

Shot offhand:
M48 plastered bottles.
Kodiak plastered bottles.

75 Yards.
Shot from sand bag:
M48 Turned elevation one whole rotation: 5-shot group covered by a 4" circle, shotgun shells sent flying after three misses to right (trigger is freaking me out!), steel plate knocked over but SLOW to fall.

Kodiak Turned elevation 1 1/8 rotation: 5-shot group covered by a 3" circle, shotgun shells sent flying after 2 misses to left, steel plate knocked over but SLOW to fall.

Shot offhand:
M48 plastered bottles (holding to the left).
Kodiak plastered bottles (holding to right).

100 Yards.
Shot from sand bag:
M48 Turned elevation another half rotation and scope maxed out. Held lower quarter of retical on center of target: 5-shot group covered by disgrace, shotgun shells impossible. Steel plate knocked over but SLOW to fall. Almost at minimum energy needed to tip them over.

Kodiak Turned elevation another 1 1/8 rotation: 5-shot group covered by 6" circle, shotgun shells avoided. Steel plate knocked over but SLOW to fall. Almost at minimum energy needed to tip them over.

Shot offhand:
M48 plastered bottles after 5 misses. Nailed all three in a row.
Kodiak plastered bottles.


The advantage that appears to go to the Kodiak is just a scoping problem. It is harder than hell to hold an estimated cross hair on a target when you are trained to look at the actual cross hair. The Kodiak could be aimed directly at the targets, while the M48 had to use a hold over at 100 yards due to scope limits.

While the Kodiak is generally considered more powerful than the M48, for the sake of these tests the advantage is not really seen. The drop from 45 to 75 yards, and 75 to 100 yards is nearly identical for both. Then energy delivered from both was also barely enough to tip those steel plates.

If anything, I give the Kodiak the blue ribbon for its trigger. That T05 trigger on the M48 is becoming a nightmare. Sloppy side to side play and sort of creepy.

What a GREAT session. It answered my question about whether or not I could use these .25 ers for rimfire silhouette distances. I can't wait until the leagues start again. This is gonna be fun.

I hope somebody some day do this kinda tests using .22 (With shells and stell plate)

Hey man can you please tell us how much power (FT/lbs) these rifles were producing when these tests were done..

Sorry, Inder...

...I didn't chrony them.

Since I can't effectively grasp the difference between 12FPE and 30FPE, I used the steel plates to answer a simple question:

"Is there enough FPE left over at NRA Silhouette distances to knock over the targets?"

The answer is a resounding "Yeah, Baby!"
