Not that brand??
I've got some bags of pistol bullets that look similar to those in color/texture (?). Got them from Midway years ago. Used them in the 9MM and .357 SIG.
No loading data back then, that I could find anyway.
No issues loading them. Did the same things to the case that I did with lead or jacketed bullets as far as case prep/priming/powder charging, seating and crimping.
They fed/chambered fine in the M&P and XDM.
As I remember, accuracy was not great - but none of those pistols hold a candle to the groups I get with my CZs so it may not have been the bullets but rather the pistols that resulted in poor groups.
I was using AA#5 from my brother's stash left to me when he passed away. Don't recall using other powders.
I did buy some .223 bullets (55 grains in weight but also much longer than a std. jacketed 55 grain .224" diameter bullet) and tried working up some loads with those. I only recall using CFE223 in that effort and never got decent 25 yd. groups so I never shot them farther. That was only in one AR15 and it did function normally, it just didn't shoot good groups with those bullets (I believe those were made in Australia, if I remember correctly.) For these there was, again, no reloading data, so I measured bullet length and found it was pretty close to the 75 grain match bullets used in .223 Rem. loading. So I started with that bullet's starting loads and worked up. I figured the longer bullets meant more bullet in the case which reduced internal volume so I didn't even try standard 55 grain bullet powder charges.
At least this outfit has some reloading data on their web page. Good luck with it.
