Their are some interesting different bullets out there which haven't been explored such as Winchester and Berry's offer. Not everyone has a place or gel to do testing but if you get a box of bullets and can spare a couple, Chopinbloc I'm sure will work them up and fire them.
I'd be happy to, but I can either just load a few at moderate charges and test only those or I can do a real work up to get to higher speeds, which would take 25 rounds or so. I like to back off the book max by about 1 gr and work up in 0.2 gr increments. Each charge weight needs 5 rounds to get a good sense of what the velocities are doing so that puts the total work up at 25 rounds. I doubt anyone would want to give me a quarter box of bullets and I'm certainly not willing to shoot anyone else's hand loads.
I thought most bullets come in 1000 packs but don't reload. The Berry bullets would be neat to see and I need to get an all Copper to you. I was waiting on Kevin but may just grab a box of Buffalo Bore.
Plus bullets offered by Magtech that no one ever talks about.
I tested a number of Magtech hollow points about 10 years ago; they were similar in performance to Montana Gold or other generic hollow points. In other words, some expansion, generally with the jacket coming off early, nothing very impressive.

You tested their solid copper line too?
No, just the traditional hollow points. As far as I know, they didn't have the solid copper stuff at that time. Only Barnes and those Taurus Hex bullets were available to me then. (The Taurus was made by Barnes, I'm pretty sure. They worked well.)
In 10mm Auto I would like to see an expansion capability comparison and penetration depth copmarison between both the 125gr Barnes XPB and the 130gr Magtech Copper JHP from a bone stock G20 loaded to a safe maximum the G20 can handle toward velocity of each.
I'd still like to test some all copper but I'm less interested now that I've seen the velocity you posted for them. They look like .40 S&W speeds with 10mm pressure. I presume it's because of the long bearing surface.
I didn't post a velocity for them. The solid copper bullets in 125-130 grains can be loaded to some pretty decent velocity. Just not in direct comparison to the likes of a 135gr Nosler lead core bullet. Still quite respectable though.

Non-lead bullets are not very handgun-friendly. As long as you don't try to compare them to their lead counterparts, they do pretty well. They are long, about 135% by weight. My 10mm hunting round is the 155 gr. Tac-XP at 1500 FPS. If I had a lead option, I wouldn't mess with them. They are accurate and flat shooting, but lack terminal performance options. At the same time, the Hornady Mono-Flex .30-30 bullet is about as good as it gets, for .30-30. 140 gr. at 2600 FPS from my rifle. My son's .50 ML does well with Barnes sabots. In most of CA, it's only legal to shoot 2 legged critters with lead bullets.

I'm sorry. I must have mistaken you for someone else. Might have even been a different 10mm forum. I was just reading a thread a few days ago where someone had posted data for Barnes copper bullets and the velocities were about what you would expect out of .40 S&W for lead bullets of the same weight.
No problem.
I'm about to start reloading 10mm and have a box of Berry's 180 gr FP. I would gladdly send 25 to someone to do some testing since there isn't much out there for info on these.
How fast are you looking to push these? If you want a sort of medium, 1,200ish load, I'd be happy to just back off from what I've done with other 180 gr bullets and I'd only need a couple to do the test. If you want to push them around 1,300ish, I'd have to do a proper workup.
I have loaded the Barnes 140 TAC-XP and tested them using the data I worked up for 200 grain XTP's because the lengths were the same. I think I could do better velocity wise if I were pushing them with 800X which I didn't have at the time.
I will say I like their expansion which is as advertised at the data I worked with, the cost is somewhat prohibitive for playing around with those but in my opinion they would be excelent hunting or self defensive rounds loaded to higher performance levels.

Raggedyman I'm only looking to go 1150-1200 max with the Berry's 180 FP
SO far I haven't loaded much at all for 10, but for 180 gr at about 1,200 I just finished up 100 or so using 8.7-8.8 gr 800X and I have to say--I'm impressed with this modest, 570 ft*lb load. Very pleasant to shoot and yet no where near as soft and weak as the factory Federals (180 FMJ) I had on hand. I believe this is a high potential load, maybe boosted a tenth or two.
