Sam Yang Industries Big Bore .44 909 Testing
I got the Sam Yang Industries Big Bore .44 909s from Pyramydair about 1 months ago.
First impressions of the gun was quite nice. The fit and finish of the gun was more than on par for the price range. The 909s weighs in at around 7.5 lbs, and balances quite nicely for easy shooting.
Barrel is rifled. Very nice wood and engraving on receiver.
Shooting components:
I bought a used Scuba tank (3000 ftp) for filling, because I heard it goes through a lot of air. I will be able to fill the rifle to 3000 psi and the gun showed no lockups at that pressure.
I bought Round nose Pellets in the 170 gr. weight to do my testing.
I Mic’d a few of the Pellets and found them to be .4565 to .457 in size.
Manual state I can use any .457 Roundball or Lead Bullets and Pellets in the .456 - .457 size.
I barrowed a friends Chronograph to check velocities so I could get some numbers for this testing session.
Shooting comments:
I did all my shooting using a sitting bench and sand bags for support.
After zeroing the rifle at 25 yards, I refilled (3000 Ftp) the tank to start with a fill tank and planed to only shoot in 5 shot grouping. The plan was to refilling it after each 5 shoot grouping so all the groups would be is the same velocities range..
Accuracy is good. At 25 yards, all holes 1 1/2 inch grouping.
At 50 yards out was getting about 2 1/2 inch groups. See pictures below….
For the penetration test, I used a 2x4 post at 25 and 50 yards.
The 170 gr. Round nose Pellet pulverize a 2x4 post at both ranges.
Here are the numbers:
Velocity average was 710 fps ( 5 shots, used the Chronograph for this findings )
Muzzle Energy was a average of 189 fpe ( I used bullet calculator for this findings )
I will be trying some 190 gr. Round nose pellets on my next trip. These should increase the Muzzle Energy..
Being a air rifle, I was surprised the gun is quite loud.
The gun has a fair amount of recoil to it, so you should use good mounts, if you decide to use a scope.
But, being I will be shooting mine under 50 yards, I will not be putting a scope on.
The only bad points to this rifle is that the trigger has a fair amount of creep and the loading port is a bit awkward and will take a little time getting used of.
If your going to put a scope on it, you will need high mounts.
The rear sight sits fairly high and your going to have to plan on taking it off.
I'm not sure that I'd want to take anything pass 50 yards with it.
So using it within that range, the regualer sites should do just fine for game up to the size of deer.
Comments after this shooting session:
I found this rifle to be Powerful and Accurate.
I think it was worth the funds I put into it..
The real test will be this coming Deer season…
