Its your pistol. Do whatever makes you happy.
I read the loading manuals,too!! I had my cool Colt 38 Super,Too!! I saw the Blue Dot loads,too!!
Now,please don't take my next statement personally. I'm applying it to myself,and my adventure with loading a 38 Super in a 1911 hot with Blue Dot.
Its a quote from William Blake,found in his "Proverbs from Hell"
"If a Fool will persist in his Folly.
He will become Wise"
Also to be found there: "All attempts at Foolproofing are folly,for the genius of the fool is infinite".
A lot of William Blakes work,I simply cannot comprehend. I think I'm missing some common knowledge from 18th Century Britain.(His time)
But,IMO,some of what he wrote I find brilliant.
I still have a couple of 38 Supers. I don't use Blue Dot
Power Pistol and Longshot? Yes.
I was given a top level Champion competitor's 38 Super .I then gave it to my brother.Its a single stack comped race gun.Supported,ramped barrel.Built by Guncraft.
For fourty years plus its run on 1400 fps ,over 40,000 psi loads.
Its slick,tight,like new,and runs like a watch.
It even has a trick swinging trigger,like a revolver. Mr Ben built some fine pistols.
That gun;s engineering is so balanced..My brother borrowed a high speed video cam used to analyze industrial equiptment.. He videoed the cycling of the gun to tune the recoil spring and find what kept the gun most motionless in cycle. Better for shooting fast and accurate.
The gun runs best with a 12 lb spring.1450 fps. All things are in balance.
A 1911 will run a long time with a 12 lb spring.This one is over 40 years old.
It will beat itself to death running 24 lb spring.
And that load would soon ruin your pistol.
1280 fps will cool out a bad guy just as quickly as 1450 fps will. They punch pretty much the same hole.
But consider,with no comp,the guy shooting the 1280 fps load might get off three controlled shots in the time the 1450 fps guy gets off two.
Assuming all hit center torso,3 hits beats two hits.
