I have all three of those bullets you listed above..........
First the 135 Extremes, I bought these long ago, when Lehigh was still owned by David Fricke. I had been using the 120 Extremes, and still do, in 45 ACP. I have used and tested these extensively, and I currently carry those in any 45 ACP I have. Normally first round up, followed by 200 gr FN CEB Solids......... My load in 45 ACP with the 120s is 10/WSF... 18600 PSI, not even Plus P pressures, but in 5 inch guns it gives 1478 fps, 4 inch guns 1392 fps, 3 inch guns like the Kimber Ultras 1275 fps and currently in my 45 ACP Shield 1330 fps.
I bought the 135 Extremes in 2018 or so, and at that time they advertised .452. So I was thinking 45 Colt, and a good bullet for my lighter frame 45 Colt revolvers such as my various 5 shot Taurus guns. Figured this would be a very good step up for those guns. I was thinking lighter loads, and started with 8 gr Unique, thinking to work my way up from there. Well results were extremely poor, my test gun was a 6 inch S&W Custom shop gun, and they stuck in the barrel? I did not know it, as I was getting some sort of reading on the Lab Radar, like 500-600 fps? I fired three rounds, and did not see holes in the target? Finally I stopped, checked the gun, and the barrel was totally blocked. Try as I might, I could not get those bullets out of the barrel....... I even put the gun in a drill press, drilled a hole in the middle of the bullets, did my best to beat them out with a big screw driver, and the damn screw driver became stuck in the barrel!!!!!!!!!!! Talk about a "ClusterF**K".......... Finally I got sick of it, boxed it up, sent it to Brian at SSK and told him I better not hear a damn thing of this, just fix it........ No laughing allowed. Sending big S&W with a screwdriver stuck in the barrel.... LOL...... I think I took photos somewhere... I measured that batch (Lehigh at the time was not known as the best quality control and things can slip by them)....... they measured .450. Why they did not have enough to exit I can only guess, blow by maybe, not building enough pressure or what have you I don't know. I ended up loading them out in 45 ACP and they did great and shot well......... I never did try again after that in 45 Colt.......
With Lehigh being sold now to Wilson, I expect Quality Control to be much better, even though I am not much of a Wilson fan....... I think they will do a much better job with the bullets, and from what I have seen so far they are not disappointing me........
I also have some of the 205s you show and I think some 220s and other .452 caliber bullets. But, I have been playing with those in 450 Bushmaster, and not 45 Colt, but I might try some in the near future. I have some loads with LilGun in 450 Bushmaster that pushes the 205 and 220s to over 2500 fps..... The problem I am having currently is feeding in the semi guns. But I think I am getting close to solving that issue with seating depth, and Dura Mag Magazines......... future tests will tell for sure.......
Almost a year ago my Son Mark David wanted some premium bullets for his J Frame Smith he likes to carry, I too looked hard at the 100 Lehigh Extremes and got a couple of boxes to try out. I don't load much 38 or 357 at all..... just don't care much for them. I went to work with Bullseye, Red Dot, WSF, and V-3N37 in both 357 and 38 Spl.
In the end I went with 8/V-3N37 for 961 fps in 2 inches, 986 fps in 2.5 inches and 1131 fps in 4 inches of gun. I tried up to 9/V-3N37 in the 2 inch J Frame at 1093 fps and just found it too much, pressures might have been fine, but it was more than I cared for, so settled back to 960 fps with 8 gr.
In 357 I tried 18/2400 also for 1114 in 2.5 inch gun. I still have not loaded any in 357.
I did load several batches of 38 Special with 8/V-3N37,
@BatteryOaksBilly has some of that batch I think........ Of course I think he is a little disappointed in velocity, and they don't have a big ball of fire coming out...... HEH HEH........
In 9mm I much prefer the 90 Lehighs, and have loaded and tested those extensively with 7.5/V-3N37 at 35700 PSI and 1468 fps in 5 inch guns, 1422 fps in 4 inch Brownings, and 1295 fps in my Shields. I also like the 115 Lehighs at 5/Bullseye at 38500 PSI and 1250 fps in 5 inch guns. I don't shoot or carry the 115s, but have them close by. I do carry and use the 90 Lehighs extensively in every 9mm gun I have. I did test and play with the 68 gr 9mm bullet with 6/Bullseye 31000 PSI and 1600 fps in 5 inch guns, but still like the 90 Lehigh overall better..............
You saw some examples of the 9mm bullets above, these are my favorite 45 ACP bullets.........
Now just to give you a comparison of "Conventional Expanding " Bullets that you might be familiar with, just to show the difference between new Bullet Tech and Old.....
