What is the heaviest you should use in a springer?

When I was taking care of my brother's .177 R9 (when living in WV years ago) he liked the 10.5 grain Crosman Premiers because they penetrated well and bucked the wind a bit better. When he was shooting 10.5s I would replace a failed Maccari aftermarket spring every other season. A few years before I moved from WV my brother found that the flatter trajectory of the lighter 7.9 grain Crosman Premier light trumped the slightly bettter wind resistance of the "heavies" and switched. After switching to the 7.9 grain pellet I only replaced one Maccari spring that spent half of it's life shooting "heavies" and the last replacement spring lasted several seasons and was "unbroken" when I moved to North Carolina. I moved about 11 years ago so I don't know how the spring held up after I moved but I do know that the .177 R9 got over twice the spring life shooting 7.9s than he got shooting 10.5s.

Still, if a person has some mechanical ability and consults a few YouTube "tuning videos" replacing a spring every once in a while isn't a big deal, simply shoot whatever pellet is most accurate for you since springs and piston seals are considered consumables. While my brother found that the flatter trajectory of the 7.9 grain CPL was beneficial for squirrel hunting he got a tad better accuracy with the 10.5 CPH as long as he "guesstimated" the holdover properly.

Here are a couple 3 shot groups he shot at one sitting with the CPH..............

That is some fine 50 yd. shooting!

Yep....I told my brother that it was simply "dumb luck" with his break barrel but I guess he was "lucky" twice in a row. I also figured that two 3 shot groups back to back are at least as good as one 5 shot group. That .177 R9 was my original R9 that was tuned by myself and sold to him for squirrel hunting. At that time always used "3 shot powder burner groups" and he had that target in his wallet to show me. I took a pic of the target with my digital camera years ago and uploaded it to a photo hosting site.
Don't tell anyone but I think those two groups were simply "dumb luck", especially since they were shot off a bench and I can't get my springers to shoot well from a bench at all!

Let’s talk about a rifle that can shoot .177, .22 & .25.
The RWS 52/54.....
The main spring used in these rifles regardless of the caliber is the same.
If you want to replace the main spring in your RWS 34, 48, 52, 54 using a spring from VORTEK...it is the same spring, regardless of the caliber
A pellet that is too light will do more damage to your rifle then will a heavy one.
You must keep the spring lubricated...
Why do the valve springs in your car go for thousands and thousands of miles?
They compress and expand thousands of times a minute yet they never seem to break.
Lubrication!!!!!!!
You may not have to lube your synthetic piston seal (I do) but you have to lube your spring!
The RWS owner’s manual is very clear on the subject.
No lube?
Broken spring!

Kind of along the lines I think Ed was saying, I would a try all pellets heavy and light.  Pick the most accurate.  If it happens to be a heavy pellet then use that pellet.  Springs are cheap and easy to swap.  The decision will be how much more accurate, assuming the most accurate is a heavy pellet, than a lighter pellet?  If they are really close it may not be worth it to shoot a heavier pellet in trade for a flatter shooting light pellet.  Common theory is a heavier pellet in a spring rifle will degrade the spring quicker than a lighter pellet.  That's probably true but plenty of people will post the contrary to that.  Personally I find the best shooting pellet and then decide, if it's a heavy pellet, if the accuracy is so great that it is worth the extra issues with proper range finding to be able to fully realize the accuracy gained.  A lighter pellets can cover siins of miss ranged targets.  Like Ed I shoot field target and accurately ranging targets is king.  Hunting would also apply the same as FT.  If you just shoot targets at known ranges then just shoot the most accurate pellet no matter the weight.  If a spring breaks buy a $15-20 spring and roll on.

Thanks guys I’m just a dummy to all this stuff

~~~~ try all pellets heavy and light.  Pick the most accurate. 

This is all you ever need to know.
