Tippmann Arms M4 22

John,
I have always marvelled that a variety of .22 work or don't work in certain weapons, but side by side they are identical? CCI seem to work with everything and are probably the cheapest out there

Its odd isn't it Gil, .22 semi's are fickle beasts. The .22 conversion kit in my L1A1 is by far the most reliable semi automatic I have shot to date, failures are very few and far between. It does require HV ammo to shoot well though, Mini Mags work best.

I think a lot is down to the long bolt travel of the L12A1 bolt group and the large port to chuck out the spent case. I have a feeling the reason the Tippmenn appears to operate so reliably is also down to long bolt travel. The short stroke bolt group in my old Spikes Tactical used to jam spent cases quite often.

The quality of .22 lr ammo does vary, ever tried Remington Thunderbolt ....They are truly horrible quality ... God knows what the propellant is, smokes like a steam train and covers everything with sooty residue! My best guess would be black powder mixed with curry powder ... Looking at the consistency of the groups, I guess some have way more curry powder than others.
