Rimfire Accuracy

SOmething has been bugging me. IS the accuracy of a good old fashioned 10/22 in 22lr dependent upon the quality of how the bullet is crimped into the case?

my current made dynapoints, have shoddy crimping quality. What i mean is the bullets are crimped in the case, but they wobble from side to side. And when i shake the loaded magazine, it sounds like a toddlers toy rattle..
Not surprisingly they dont group extremely well, however i dont know if its random powder charges or the crimping. I can usually shoot the same size grouping at 20 yards that i can at 60 yards if i use the same scope magnification and rest.

My current cb caps and 20 cci maxi mags have excellent crimping and bullet tightness (ie like a 30-06 from the factory). They shoot very well for me, and typically dont like long range.


IS this a situation of mere quality control or just how the bullet is crimped in? I hypothesize loose crimped bullet = bad accuracy as everything i read about percussion revolvers say "a canted conical will open up the grouping and lower acuracy".

I'm sure that is one of the things that can effect the accuracy, but there is a lot more to it than that as well. Consistancy in construction and components also have a lot to do with accuracy. While a lot of people can get good accuracy with Dynapoints I don't believe they are marketed as a "match" bullet nor are they priced as such. When you start to get into the match bullet catagory for the rimfire ammo, you can spend more for a box of 50 than what a brick of 500 Dynapoints go for.

actualy, as part of the whole, the tightness of the crimp. proly plays the smallest part. your chamber will be number one storyteller, as far as right there, where the round seats in. that chamber and the beginning of the bbl lands, is gonna hold that round in place, once the primer goes off, more than the crimp will. case length,overall lenght, bullet seating depth, case thickness, primer charge, powder charge, rim thickness, rim diameter, case diameter, overall weight, etc., ad nauseum, will all have greater effects on accuracy, than the tightness of that crimp.
