I have a new cronograph and I finaly got down to shooting the .177 caliber 1000 SB. I have been playing with my Gamo CFX in .22 Caliber, and my new Genesis 1000 in .177.
Now that Genesis is a sweet rifle not as powerfull as the Winchester so far, but the trigger is so fine and light.

The numbers are something to look at as far as pellet weights and shot differences. Tells a little as how good the pellet sizes are, pellets with a high figure between the high and low velocities are not as uniform.

So here they are i hope I did everythig right. the numbers look OK.

I wonder why this energy loss with heavier pellets. Premiers Hollow Points seem to be optimal.

Heavier pellets are not as fast and lose energy quicker.

I found out by shooting my rifle that the preimier HP's are by far the most accurate. "and they are cheap at Wal Mart"
They have the least difference between high and low speeds
only 11.2 FPS.

Crow mags. have more energy but if the pellets vary to much afecting a accuracy. They shoot OK in my rifle but I go with the HP's The HP's group under an Inch a 35 yds.

There are 2 crows and 3 squirrls that found this out, all taken beyond 35 yds, one crow was almost 50 yards out and I nailed him, I paced it off going out to get him.

I bought a Reminton Genesis 1000 last week and I am working on it now, just lubed it up and just about have 500 rounds through it. The rifle has one sweet trigger, I can't think of anything I can do to inprove it. Light and clean pull: Super. Power is comming up in the rifle fast, shoots those little Raptors at over 1190 FPS. It would'nt break 800 when i first fired it.

Actually heavier pellets usually lose energy slower than light ones, example: crosman premiers at 10.5gr and crosman premiers lights at 7.9gr. The heavy ones have a larger ballistic coefficient. Let's say CP10.5 have initial velocity of 800fps and CP7.9 - 950fps, at 70 yards they will have the same velocity, but CP10.5gr ones will have more energy. It's interesting that 1000x's initial energy is more with light pellets. I know this is not so with pump guns, as for springers they seem to be all different.

The heaver pellet? Where does the weight hurt it.
"Friction"

A heaver pellet is larger so it should slow down at a quicker rate. Still should have a edge over the light pellet, but how much ??

In all my guns, the heavier the pellet, the less the muzzle energy.  Since we are talking about Winchesters here, according to my chrony and my ballistics program, I have the following results for my Brazilian 1000X (which has quite a few shots through it!):

In my case also the heavier the pellet, the less muzzle energy, but down range, the heavier the pellet, the greater the energy (some other factors apply as well, as fit, friction, how the skirt holds the air, and ballistic coeficients, but as a rule of thumb, it holds somewhat true).

As you can see, the best results are from Beeman FTS for general purpuse, and Beeman Crow Mags for hollowpoints as far as energy goes.  However, due to the differences in speed, I prefer the Super-H-Points because of the flatter trajectory for hollowpoints.  In the case of the Superdomes, the standard deviation is less than in the FTS, but either works fine.

I see said the blind man. Nice balistic program what is the cost and where? I think i am going to sell my F-1 Crony and get the Gamma? or which ever one figures the shot strings for you. The F-1 works great but more Info would be better, less time with a caculator.




I myself, am more intrested in how tight the rifle will shoot. A well placed shot gets them vevry time. My Win 1000x with preimier HP's can group at 3/4 to 1 inch at 45 yards. This is what I like about the Win 1000 and tyhe more pellets I shoot the better it has got.

I am now in the process of breaking in my new Genesis, the rifle is just comming up to speed and the groups are getting much better. The rifle has a few flaws but nothing that can't be fixed. Barrel pivot comes loose, "locktite"
Super trigger, a real two stage with light pull.

You just need to take an old pair of headphones, cut the earbuds out and expose the cables, and simply make contact between the cables.  The thing will give you averages, std dev., etc...  Give it a shot before you sell yours and buy a new chrony.

Kool !!! I guess I'll keep it.

That works great. THANKS !!

I'll buy a chrony one day and have some fun measuring all velocities and posting them. I actually had a chrony, but it broke, and I've been buying other stuff lately to buy another one.

The larger the ballistic coefficient (heavy pellets BC > light pellets BC, as a rule), the slower its velocity drops = more energy kept at large distances.

Exiting the barrel CP10.5s move slower than CP7.9s, but at a certain distance these two will have the same energy. That's why it makes sense to hunt with heavier pellets at large distances. Although hunting past 70 yards where they'll have the same energy with Winchester 1000s is a pure chance. Of course, weight is not the only thing that affects the BC of a pellet. But all other things being equal, weight comes into play. When hunting paper targets all this knowledge is a nuisance though :)
