This is a smart approach, and I do so regardless of caliber. I've had a number of finicky .22LR semi-autos over the years, and found it to be more cost-effective to buy a variety of ammo for a new gun than just stocking up on whatever worked for me with other guns. For instance, I had a Walther that liked old round-nosed lead Federal Lightning, but a Ruger that wouldn't run anything reliably except Winchester copper-plated Super-X, as I recall. I haven't really experienced anywhere near that level of "selective ammo appetite" in other calibers, but I still use the same approach: buy one or two boxes each of a couple different brands.Since many weapons chambered in 22 LR are ammo sensitive, I often test a new weapon with a variety of different ammo, to see which function and shoot the best.
I once measured Remington Thunderduds, the epitome of mass-market ammo, and found bullet diameters as large as .226". How they managed to do this I don't know, but there it is. Other bulk-grade ammo I tested was all in the .224 range, but varied enough that .2235 was not uncommon. Eley Sport was consistently .2235". I cannot find in my notes that any ammo tested was consistently .2230". That test was done in 2012....it's been a while.Copper plated advantage is for semi-autos to reduce gunk in action from buildup of waxy or greasy bullet lubes. The cladding must be heavy enough to prevent the rifling from cutting through the plating and exposing bare, unlubricated lead in the bore, which will cause leading.
Plated ammo tends to be less accurate because the bullet bases get damaged when tumbling the bullets around in a barrel plater to apply the copper. CCI Mini-Mags are the exception to this because they plate the bullets as pre-formed cores and not as finished bullets, so that the bullets are finish-struck after plating so that the bases remain good.
But plain lead, unplated bullets are usually more accurate in revolvers than plated types, because their basic bullet diameter is larger. Waxed or greased bullets lead less in revolvers.
Most important thing for accuracy in .22 LR ammo is the bullet diameter, as measured at the exposed bearing surface outside the case. Max. bullet diameter is .2255" and you want as close to this diameter as possible. Only way to get .225" all the time is to buy Eley Tenex or RWS R50 match ammo.
US made mass-market .22 LR ammo bullet diameters are .223" diameter or less so that it will feed in crudded up semi-auto chambers that people never clean. "Sporting" .22 LR chamber is .227-.230" which makes for sloppy fit. "Match" chamber is .2245-.2255"
CCI Green Tag and CCI Standard Velocity is .224" bullet diameter, much better if you want to shoot ten-shot, 50-yard groups consistently under 1", with the best groups from a target bolt rifle approaching this with 10X scope at 100 yards.
No. The first plated .22 bullets that I know of were the Western Cartridge Company "Lubaloy" bullets which appeared about 1930. They also applied plating to .38 Special bullets. It is by no means a new process.Where stingers the first plated bullets? I ask because that was the only .22lr bullet my grandpa would buy. He died before I was old enough to ask.
Less transfer of lead onto your hands and thus lead poisoning after you've been handling it. Lead poisoning's not terrible for an adult, just lowers the capacity of oxygen that your blood can hold, and it's relatively temporary. Can do permanent damage to any kids you contaminate though.I did a search and came up empty, so I will ask here.
What, if any, advantage is there to copper-plated .22 LR rounds vs. bare lead rounds, or vice-versa?
Back in 2012 I did a long study of .22 ammo, mainly just getting weight variance data, but also studying the effect of "bumping" to make bullet diameter a uniform .2250". I did not find ANY American made "target" ammo that scored well on weight variance. CCI Standard Velocity was just as good. MiniMags were pretty close.I use plated ammo when I'm just plinking. I stay away from the Remington Target "green box" stuff. I had a LOT of misfires with that stuff. That was about fifteen years back and I just stopped buying it. Haven't bought any to this day.
