700X and the 45ACP

[dale2242]

I was given a 12 lb keg of 700X powder. I will load some shot shells with it, but plan to load mostly 45 ACPs and cast boolits. Are any of you using it with cast in the biscuit chunker and what loads?---dale

Start with 3.5 grains 700X, with any boolit in the ACP. That powder comes on fast when cornered, so watch for a sudden increase in speed as you increase the volume of powder. Up until that demarcation point, it is reasonably smooth in response and falls within expectations. Just guessing, I would say 30K cup is that point, and that would be far too much for the longevity of the pistol. Tailor the load on hand to where the ejected case falls immediately to your right, 90 degrees. If the case ejects back behind you more, reduce the charge or increase the spring weight. ... felix

WoW!

Good for you!

It's a very good 45 ACP powder, approximately similar to Red Dot in velocity per charge weight or perhaps a slight bit less.

4.7 grains gets ball equivalent velocities with 230 grain lead roundnose bullets in my 1911's (five inch).

Take up skeet until you use that stuff up. Lots of folks tout it for .45 ACP but it is a sure way to crack a slide. It gets real hot real quick and I am talking about .2 grains fluctuation.

Very interesting, I'm using 6 gr. of 700-X for my Uberti 1873 Winchester in .45 Colt. It's a tack driver at 50 yds and not too much worse at 100. I like it.. One of these days I have to chrony the load and see what they are doing.

I have been using it in My 9mm. 124 grain TC boolit with 3.6 grains 700x. More accuracy than the store boughts, but also a lot more barrel fouling and smoke at the muzzle. I plan to load with it in the .45 as well as I have 8 LBS of it.

Dan, since I've used it on and off for the last 25 years in 45 ACP, you may guess whether I believe it will "crack a slide" or not.

It's been used in charges from 4 to 4.8 grains during that time, per the loading manuals. Never a problem.

For 12 ga. trap, 9mm cast and 45 cast. My current load is 4.5 behind a Lee TL 230 bullet. Use it for subguns. Grease gun and Reising have shot several thousands of this loading. They don't sell it by the 12 lb anymore, only the 8 lb..

I have been using it for years and load it per the manuals. Works great for me and my 45's

[bowhunter]

I too have been loading iy for years in my 45, around 4.5 gr with 185 gr. It is very accurate. No problems.

I've got plans to try 800X on my next trip to the range, .45 and .44 first.

By the way, if I move to Oregon will you introduce me to your friend? :drinks:

I also have a 12 lb. keg bought in early 80's. Made by DuPont before it became IMR. Used 200 grn. H&G 68 equiv and 3.5 gr. 700-X in Clark long slide 45 for NRA bullseye competition. Used this load for some years until my eyes got bad and had to have a red dot scope installed. This caused problems with ejection when some cases got jammed between top of the slide and bottom of the scope mount. Increased to 4.0 grains for stronger ejection. This works well, and 4.0 is still a relatively mild load.

Also use 2.8 of 700X with .38 spl. 148 grn. wadcutters in a Clark long slide. This is a mild load for target. It is a bulkier powder than Alliant Bullseye, and fills the case somewhat better. I also notice 700-X is cleaner than Bullseye. I have heard about uneven charge weight, but my Dillon powder measure holds to within 0.1 grain.
