I read with great interest many comments about testing different pellets to find the most accurate with a particular gun. I'm assuming much of this accuracy testing is done with a rifle, optical sights and from a stable rest. All most all of my shooting (including PBs) is done offhand with open sighted pistols at either 30 or 50 feet. I'm oldish and shakey with bad eyes and I'm pretty pleased when I shoot a 2" group. I'm not convinced that any particular pellet will make a big difference so I shoot whatever is cheapest at Walmart. Maybe someday when I'm feeling wealthier I'll buy some fancy target pellets. Maybe I'll be able to shoot a 1" group offhand at 50 feet. LOL, Maybe not.
I've done blind random comparisons. There are two big factors. First is pellet diameter. The best shooting pellets tend to be ones that are just tight enough to engage the rifling well. Too tight and they seem to suffer from friction issues. Too loose and they don't reliably engage the rifling. Most of the better manufactures make a couple different sizes. RWS that I've measured come in 4.42 or 4.38. My Gamo rifles like the RWS 4.38 such as the Superdome or the Basic Match. The Hobby Match is 4.42, where the Basic Match is 4.38.Second is pellet consistency. I've measured the crosman pelets in the tin and they are all over the place. That's actually how I did my blind tests. I measured and separated crosmans by size. Very low quality control there. There was a spread from about 4.36-4.44. If you gun likes them loose and every fifth pellet is tight, you're just not going to get consistent results unless you measure them and only use the ones your gun likes.....OR.... just buy higher quality consistently sized pellets (like RWS). I have heard that the Boxed Crosman pellets are consistent but I have not confirmed this. If you're worried about weight, just know that consistency is consistency, if they are consistent on size, they are going to be consistent on weight as well.
I listen to the rifle when it fires and watch downrange for the landing. I don't have any rifles that are picky about what pellets I use, but the CPs @10.5 grains works well in all my .177s. I would think the heaviest pellet to launch is the easiest on the springer.
Absolutely it matters, you can shoot a good pellet poorly but you can't shoot a bad pellet well. Meaning one that is matched to your gun.
You can get excellent results with one pellet at certain weather conditions, but as soon as conditions are changed, you get the shotgun.
"heaviest pellet to launch is the easiest on the springer." If you're speaking of pellet weight vs spring life then my experience is quite the opposite.
… I'm sure the accuracy difference is there but how significant do shooters here find it compared to all the other variables when shooting pistols off hand? ...
How long does an HW50 and R7 last shooting light v heavy pellets?
