Are there a number of competitors who shoot 45s in SSP?

I wouldn't say there are many. Actually I don't recall the last time I saw one right off hand.

New to the game and starting with a 9mm. Soaking up the info on heavy bullets/light springs, it would seem a 240gr @ 688fps would be a nice "woose" load.

I've shot .45 Minor in ESP.
A 200 at 650 f = 130,000 is very mild, punches big holes worth a couple of points a match, and is easy to tune a 1911 for. I have some custom 9 round .45 magazines that fit The Box and a shopbuilt equivalent of an STI Eagle that lets me load 10+1.
I don't know about SSP, getting some DA .45 to shoot such light loads might be harder.
Dan Burwell said he had a customer try it with a Plastic M&P .45 without much luck.
You could see what it would take to run a Glock or some such and see how the recoil felt.

In SSP (and ESP), you only need to make 125k power factor in 9mm and would be competing against that. If that number applies to .45s in SSP also (honestly not sure if it does) 230gr @ 544fps would be all you need. Whether that is a practically do-able/reliable load, I also don't know (not a .45 shooter).
If you are out there shooting against only yourself, lots of DA .45's technically qualify for SSP and would be fine to shoot. If you are in it to win and want to shoot .45, CDP is probably your best bet. The high level SSP and ESP shooters all tend to run 147gr 9's @860 or so.

Back before ESR existed, 625's with 230's blasting down range (OK, you could watch them flying to the target) at < 600fps ruled.

I am in the process of developing my load for the 9. 147s at 850+ with lighter springs (started with 15#) is very doable. "course we all know its what is holding the pistol.
Last year I experimented with 1911 working up a load for informal IPSC (yea, I'm that old). 155gr LTC w/10# spring. Never chronographed it but it was fast enough for my trigger finger but you could almost see the slide operate. Very soft, no muzzle flip.
May get a G35 and tinker. 'Course thats my problem, tinkering.
Any pet loads for the full size G 9mm?

Just dug up a box I have for BUG that I think is the same load I used to use for SSR before the last rule change. 3.0 grains of titegroup with a 230 grain berry's @ 1.125" oal, it's silly soft.
In 9mm, Berry's 147's with 3.1 of VVN310 @ 1.160" oal is the best I have found. 3.2-3.3 of titegroup instead of the 310 is a close 2nd.

I just fired two rounds of 147s with 3.0 Titegroup at 1.125. Averaged around 920fps. TG is 19 and AS is 24 on the burn rate chart. These last two rounds of TG were very snappy compared to the AS. Going to load a handful of AS, 3.3grs andgo chronoghraph.
N310 is the 3rd fastest powder on the chart. FAST! From reading but a lot were having problems with 147s keyholing with fast powders. A bunch swear by Solo 1000. They state that they cured the lousy groups and keyholing with the much slower powders.

The only keyholing problems I have seen are due to having a gain twist barrel like the AET or over crimping. Also with the N310 load above don't use it at 1.125" use 1.160" instead.

Was going to ask question along those lines. I fired a couple of 147s over 3.2AS at 1.125". Averaged around 850fps. While I realize the fps differ, the AS has a noticeably softer recoil.
In y'alls experience, what is gain/loss of seating deeper or longer using same bullet and powder. That 147 is loaded deep. If I come out to 1.250, and assuming it will cycle and eject properly, what do you think I will lose? It would be nice to go to 3.2 with a 1.250 and it comes together for a safe from penalty 125pf.

My experience comes from going to my private range and loading rounds until they make power factor then loading 20 or so with different powders and different bullets and testing them side by side. N310 is too fast with a 147 loaded shorter than 1.160” without a small rifle primer. It does however have the least perceived recoil of any load that I have found and I have tested many.
I can test four powders with three different weights of bullets to any given PF in under 2 hours with this setup.
