I am wanting to see what if any advantage I can get with the heavy 177 pellet over the 7.9 - 8.6 grain pellets I shot today.

Rifle is one of the side lever chinwerkbaus producing 875 fps with 8.6 gr pellets.

Shipping is as much as the pellets so f there are no real advantages I will just forget that as a waste of time

The only real advantage of going to heavy pellets is to bring an airgun that is shooting supersonic down below the speed of sound.
Pellets are drag stabilized and the lead pellets do not shoot well when pushed above the speed of sound.

Your gun is already subsonic, so there is no need for a heavier pellet. You might want to look at a lighter pellet and get your MV up closer to the sound barrier.

If you're happy with it's accuracy, don't mess with it.

Thank you RM.

I was just wondering about carrying the greatest impact to the longest distance I would be shooting (kitchen window to driveway) which is 57 yards.

For a cheapie chinese copy it shoots very well at that distance and if my ballistics table is correct it is only 0.37" low.

With the gun rested on a firm but soft rest, testing has provided surprising accuracy.

The trouble is that some things hear the rifle go off in time to react before the pellet gets there with a TOF of 7.66 seconds.

Just how far is your target to get a TOF of 7.66 seconds?

Assume average velocity of about 800 ft./sec.

800 X 7.66 = 6,128ft., or 1.16 miles

Little or no advantage in a spring gun but, most likely not anything that will damage like light pellets will. The 10.5's are mostly for PCP rifles that can drive them without the harsh recoil. At longer ranges the weight helps with wind drift at the cost of flat trajectory. The problem with spring guns that can move them at that velocity is they tend to be harsh shooting, lots of recoil, and hold sensitive making the tough to shoot at those ranges.

I gave up on hot springers years ago. if you need that kind of power go PCP, or bigger caliber. Even in PCP outside of field target your better off with a bigger caliber for game shooting.

airguns rely on accuracy, not power. Most small game can easily be taken with a good accurate shot at 850fps.

i was wondering the same thing. none of my high powered PCP's will shoot that far. you could roll a pellet on the ground and move it close to 50 yards in 7 1/2 seconds

This proves why one should apply the BS test in their head before accepting something spit out by the computer.

When calculated with a plain ol calculator the TOF is 0.21 seconds.

Accuracy is decent and trajectory is about right-on according to the trajectory program and for the distance covered.

Cowbirds and grackles are the target of choice.

put it this way.i have 6 Daystates( including a .303 Wolverine) all set up to shoot their "preferred" pellets at 900-925fps. and no target has EVER managed to "jump the shot"... ain't going to happen if velocity exceeds 600fps at ranges under 50 yards. and BTW, I prefer heavier pellets in all 6( muzzle energy varies from 25fpe to 95fpe). if punching paper, lighter weight generally gives a SLIGHTLY" flatter trajectory. if trying to kill something, more energy is better within reason. shoot your preferred pellet at various distances out to your maximum range and simply record holdover( or under) in 5 yard increments.i know EXACTLY where my pellets will hit in all 6 rifles out to 90 yards and 1/2 mil dot scopes on them make picking the correct aim point easy.

Pellets are not drag stabilized. They are spin stabilized. ie: There are NO smooth-bore Olympic pellet guns! The thinner material around the base allows the skirt to expand and engage the rifling. Please...

I bought my RWS .177 rifle used and the guy sent some match pellets that didn't do so well. Then I learned they were lightweight pistol pellets. I shoot 10.5 grain pellets and it does well. Several years ago there was a group buy on a mold to cast heavy pellets. 25 grainers. These pellets keyholed. Then someone said they had good results shooting them backwards. I didn't find them very accurate and penetration was poor. I'll stick to 10.5 grainers. For heavier move up to .20 cal and get the best of both worlds between the .177 and .22. If you need bigger than that go to centerfire.

i can't believe anybody ever found cast 25 gr pellets to be accurate in a .177 springer or even a .22 springer. they generally won't be accurate in a .22 PCP. i tried JSB 25 GR monsters in 3 different .22 Daystate PCP's but they were too loopy and not very accurate- and these were 40fpe guns. stick with the 10 gr pellets

This group buy 25 grain mold was to create a pellet that would carry and penetrate--all but billed to take out cape buffalo. Just opposite of what I wanted. If they made a pellet that had a parachute that opened at my property line would be ideal. It was a flop. The guy that designed it said the final product was not what he designed and it had been changed. As I said I found nothing positive it offered.

I have found no local supplier of the heavier pellet and if I order shipping costs are more than the pellets.

Oh well the ones I am using now are effective.

Just it was really the quest for something "Better".
