Bullseye question

[Ysabel Kid]

So, I've been fiddling with AI lately. Sarah Connor would be appalled.

I asked Copilot (Microsoft's AI) if the following load was safe:

Cartridge: .45 Colt
Bullet: Coated 200 grain lead round nose flat point
Case: New Starline brass
Primer: CCI 300 Large Pistol Primer
Powder: Alliant Bullseye
Charge: 7.0 grains
Barrel length: 4.75 inches

It spits back that the load is unsafe and should be considered a "Ruger only load".

Hmmm.

My Speer #13 manual lists 6.5 grains as a starting load (835 fps) and 7.5 grains as the maximum load (988 fps). Only difference is the test barrel is 6.5 inches and the bullet is a LSWC versus a LRNFP.

Yes, Bullseye is a fast burning powder. It's also pretty darn economical and I actually have a couple cans of it.

I even asked it safety changed if this was not an original Colt SAA but a modern reproduction with modern steel. It came back that it was not an issue of the steel but the design.

It did think the load was fine for a Winchester 1892 or clone.

What say ye? AI being overly cautious or have I been loading hot all these year?

I am not sure AI is a good place to get loading data.

Bullseye is fine for the .45 Colt and published loads.

Judge for yourself:

When i enter 7.5 grains of Bullseye, the pressure calculation goes up to 11,132 psi, @ 898 fps. changing the bbl length to 7.5" velocity climbs to 1,047 fps. I suspect your AI is very conservative, can't read, or has faulty data.

It’s definitely not an overload

Look at a 1950's loading manual and see what they were shooting through Colt SAA's with the 260 gr. gr. bullet.

AI sucks. I avoid it at all costs! So much disinformation, or bad information on it.
My ancient old Ideal hand books show 7.0 grs. of Bullseye with a 200 gr. cast bullet is a medium load. Not too hot, nor mild, just mid range level.

Yeah, I'm not going to get reloading recipes from AI... or the rest of the web without research on my own. But I am interested in what AI say on various topics.

For example, I asked Copilot to summarize the Colt 1862 Pocket Navy. Seconds later, a workable article that was largely correct. As I drilled down into it though, and asked some of the questions it recommended, it hit a huge error (claimed the Colt 1862 Pocket Police did not have a rebated cylinder, so was easier to convert to cartridge firing - this is simply not true). This has been my general experience - usually the first answer to a question is the most accurate, and as you drill down it gets more and more errors.

I asked Google Gemini AI why all my searches were way down the page in favor of the AI response and it said its googles aim to move away from normal searches which are like a library of articles, to having an AI curator who gives you the answer without having to enter. I asked why its so innaccurate and it said its because the programmers want it to be a prediction machine, favoring agreeablness over accuracy. It said rather than think of it as a lecturer of facts, look at it like a "Brilliant over enthusiastic junior assistant" . I have enough brainless millenials in my workplace, I dont need another one telling me stories.

You should see the SCARY stuff AI says about health and medication issues.

The problem is - Docs are often just as naive if not moreso than ordinary folks (perhaps many naively have relied on 'peer reviewed medical journals' that are mostly big-pharma mouthpieces for so long).

However, AI is infiltrating even into basic 'dictation' software - it started with spell-checker for complex words most dictation software can't handle, but then morphed into phrasing, terminology, and organization of documentation.

I see WAY too many errors introduced that physicians don't catch with 'proofreading'.

Those of us who quit accepting 'insurance' and only deal with patients, can at least spend enough time per patient visit to document and proofread fairly well (I see ten patients in a 12-hour day), but those who are 'participating providers' or 'in-network', are pushed to see 25-30 patients in 8 hours (and keep in mind four-per-hour only nets about 4-5 minutes where the doctor is in the room with the patient, because the rest of the time he/she is fiddling with the computer outside the exam room in addition to the typing so many of them do IN the exam room on top of that... )

Humans are in danger of becoming 'data entry clerks' for the 'system', the latter of which is increasingly non-human.

Sad to say it is back to the adage of"Garbage in, Garbage out." IT depends on who makes the AI and what they are pushing for views.

I have been going through some of my older loading manuals and you see some interesting patterns.

For example , in one of the old Speer manuals it says that despite the number of powders tried, they could only recommend Unique for the .45 Colt as all other available powders had excessive variation.

I shot the fifty I reloaded recently with Y2K yesterday. No problems at all. Plenty accurate. He loved them. Unfortunately, I fell last Sunday (darn foot drop), on the driveway, and hit hard on my wrist and shoulder (trying to protect my head, back, knee and hip). I'm pretty sure I sprained my wrist. I was wearing a brace on my right wrist, so not my finest shooting, and I only shot two cylinder's full before letting Y2K finish the rest. Still a great time!

AI just got a couple Oregon lawyers fined big time when they used AI to generate legal precedents for cases they worked on and turned out AI was wrong! They got caught when another lawyer did his due diligence and discovered their answers were wrong, and AI generated. The state bar was not happy at all when it was discovered! Kinda like cheating on an exam with bad info to do it.

Alliant website lists 7.5 gr. 200 LSWC 895fps. I would not trust any AI to recommend Toilet Paper, let alone load data.

[LeverGunner]

I've been dabbling with loads of 7.0 - 8.0 grains of Bullseye and the Lee 429-214-SWC in 44 Magnum. Nothing like it in any book I've seen. But I don't have an extensive selection of older data either. I will guess the 8.0 grain load is 30k psi. Shoots pretty good too.
