I have used Universal, and it is just that universal, works in most calibers, but does not excel. It is about the same speed as unique but builds higher pressure than unique. I found TG consistent, and provides excellent accuracy with moderate loads in semi auto. I am about out of Red Dot, and have not found more, but it provides low recoil for subsonic loads, and when I have used it at night low flash. It is a very fast powder, I use it in a 1911 with soft cast FP at only 800 fps. Very low recoil, less than a 9mm, not the most powerful, but very, very accurate, and controllable.So do you think TightGroup or Universal would be a better powder to go with?
I get 904 with RD out of GAP with 185 gr. A tad slower powder would give you want you want out of GAP.I'd like at least 925fps with a 185gr out of the GAP and 1125fps out of the 9x19mm with a 124gr/125gr bullet. More would be better though as long as there's little to no flash.
It has not been my experience with TG, or RD.I have no experience with it, but I believe I read that TG has a good bit of muzzle flash. Might want to research it further before purchasing any.
I love VV-3N37 for service style loads in 9mm. I have read others state that it was low flash for them, but for me it seemed to be a pretty high flash signature powder when loaded hot. No way near as low as N105. Not Power Pistol high, but higher than some of the others mentioned already. I think if I was going for a VV powder for both GAP and 9mm, I might try N340 or N350 (I like N350 a lot). There probably isn't a great deal of load data for GAP, but if I can find the box my load records are in, I can give you what I have for N350 in a 45 +P style 45 Auto. You could work up from there.My main "issue" is that when I find a powder that looks good for 9x19mm and gives me decent velocity for a 124gr/125gr HP there's no listing for it for the 45 GAP. Also, when I find a powder that works well for the 45 GAP, 185gr HP it either sucks balls in 9x19mm or there's no loading data for it.
Universal looks good in the GAP at 1027 fps for 6.3grs but in 9mm I can only get 1045 fps at 4.4grs which just isn't up to snuff.
Same deal for Tightgroup. GAP can get 974 fps which isn't great but it's also not too bad but 9mm only gets 1057 fps.
With VV 3n37 I can get 1248 fps at 6.6grs in the 9mm but there's no loading data for that powder in the GAP.
I really want to push my 9mm's to the high 11's or low 12's and I'd settle for 1150 fps if the powder would also get me mid to high 9's or low 10's in the GAP. 950 fps would be fine in the GAP but if I can break 1000 fps and get that same powder to break 1200 fps in the 9mm I'd be really happy as long as it's something the local Cabela's stocks so it'll be easy to get without driving all over town.
In 9mm, you're talking about 124/125gr jacketed bullets right? 4.4gr Universal is just about the starting load for 124gr jacketed. I try to do right between 4.3 and 4.4gr and get 1050-1120fps depending on the bullet and OAL (PD or MG FMJ/CMJ/JHP). There's room to work up and probably get up into 1150-1200fps. Universal has been my main powder for 9mm (124gr and 147gr).My main "issue" is that when I find a powder that looks good for 9x19mm and gives me decent velocity for a 124gr/125gr HP there's no listing for it for the 45 GAP.

I like to keep things as simple as possible. That's why I love the 45 GAP, I get my 45 cal bullet but I can use the same small pistol primer that I use in my 9mm. I'd like one powder to do it all so I can load both 9mm and 45 GAP so I can just stock up on one powder for the two calibers.Maybe I missed it, but why do you need only one powder for both calibers?

The whole world of ammo is starting to think as you do about primers, Frank. Large Pistol primers are likely going the way of the dodo bird, as tests have shown only very minor differences in velocity from large pistol loads using Small Pistol primers instead of Large Pistol primers. Winchester, Federal, and CCI are offering .45 ACP loads using Small Pistol primers, including in CCIs Blazer Brass. (See http://www.shootingtimes.com/ammo/small-vs-large-pistol-primers-45-acp/). It's a good article. Shooters will have to be aware of the change, as trying to stuff an LPP into an SPP hole will surely cause a heart-stopping event.I like to keep things as simple as possible.
