The 225 FTX will exhibit 3 accuracy nodes as far as I know. That was out of my 1:24 20" stock Bushy barrel. I'm reluctant to give powder charge data because the characteristics of Lil Gun changed (faster) after I wrote the article
almost 7 years ago. They are a known performer. The best accuracy I've ever achieved with my original barrel despite it having some chamber dimensional issues (little loose and little out of round). I do question the ads contention about "controlled expansion". It was designed for 45 LC velocities. Raw bullet prices unlike the 200 and 250 FTX' are for boxes of 100 not 50. If you shop around, they can be found for 26 ¢ each. The cannelure location makes it an excellent choice for the good old taper crimp. Properly applied, they stay put.
This image has gotten more mileage than any in my library and for those who have seen it over and over, I apologize. Here's my best 5-shot, 100yd
450b group, courtesy of the 225 FTX. Indeed the proof is in the pudding:
1/2 inch grid pattern.
Nice to be corroborated once in a while. However, when I sold my original barrel to fund the purchase of a Trident 1:16 twist
barrel, the recipe no longer worked as well. Not that twist alone is the only contributor to a load's performance. The Trident went to a new home and I'm back to 1:24.
