If you do a little on line research you will see what I'm talking about.
Here is one of many links on the subject:

Thats not entirely true. LOTS of guys shoot 1-20 and 1-22s at VERY high fps with smokeless (IN APPROVED GUNS) and it works fine with a 195gr or heavier bullet. The Original ads from ALL the fast twist 45 makers said to use a 155gr bullet and 3 pellets. They tried to compare them to a 7mm at the muzzle in terms of energy but the marketing was flawed...not the twist. Sabot quality has also improved but still needs some work to really make a 45cal nasty. If they made a sabot for a 300gr 405Win (.411), a 1-20 should stabilize it and you would have a solid 300 yard gun...BTW you can resize these down to fit but the sabot is just too short and weak to handle it.
That load MIGHT be fast but it isnt very likely to be accurate. Same holds true for the custom smokeless 1-20s. They don't like a 180gr unless you down load them a lot. Its also a great twist if you want to mess with sabotless and heavy amounts of BH209. Ive seen some impressive 250gr/2300fps groups but it takes some effort to size them correctly.
All White 45 were 1-20 also and shot huge 400gr+ 45s with awesome accuracy and really heavy White PowerStar 45x40cal sabots.
BTW grats Corey. Ive got a LNIB Original 45 too and with a conversion kit for the new style bolt and NFPJ (bare primer), they are SUPER clean shooters.
