Looking for a powder that will get me a solid 1200fps using 200gr, jacketed projectiles, in a stock Glock 20.

Power Pistol absolutely will not get me there. Tried 8.3gr of it, and got 1130 fps with no pressure signs. Upped it to 8.5gr, got 10fps more, and brass that was unusable.

Also, looking for a powder that meters well as well.

Anybody got any recomendations?

TRaGiK, 1200 fps is a reachable number. 800X is said to get there...even over!

I have gotten 1200 with 10.5 grains of Blue Dot, 8.0 grains of Power Pistol from my S&W1006 5", from the Glock 29 3.78" barrel not even close. I am working with the 800X and LongShot to see if I can get the numbers others say they are getting.

Hornady XTP 200gr
COAL is at 1.255"
CCI 350 primer

Everything I've read said 800x meters like corn flakes. I don't have the patience to weigh every single charge.

How's blue dot and longshot meter?

 

[Gunnut80]

Longshot meters great, +\- 0.1 grain IME. I haven't thrown Blue Dot myself but I believe I recall reading it meters fairly well.

ETA: Will AA #9 work? (anyone?) I would think it would meter better than Longshot.

Well If you are looking to achieve 1200+ fps with the 200 grain bullets you should be hand weighing each and every charge regardless of any powder, while working in this performance range! Progressive loading of cartridges in this arena doesn't leave much room for devations period! :shocked: If you don't have the time to devote to precision, do something else! :whistling:

 

[TRaGiK]

Fair enough.

I'd still rather use a powder that meters good, and that can be used for more than JUST full powered loads, without having to weigh every single charge.

I was able to get an average of 1206 FPS for a load using a 200 Grain Hornady XTP bullet and Accurate #9 powder. It was super accurate also, although the primers were flattened.

Also, Accurate #9 meters like water, as you probably know. If you have a good powder measure and have a good reloading/measuring technique, you should not have to weigh every charge. My loads seem to always stay within plus or minus 0.1 grain from my Dillon powder measure.

I think blue dot is the best powder for the 200 grain slugs. I think BD is a bit too slow for optimum efficiency in the sub 200 weight range but right on the money for the 200's. One of my favorite loads is a 200 grain bullet with 9.3 grains of blue dot, gives me numbers in the low 1200 range- now this is from a 6 inch barrel. You can go higher then 9.3 with 200 grain range, according to most reloading manuals though. I just find I dont need to with the longer barrel. also I always use winchester wlp primers

 

[Taterhead]

The only published data that I know of for 200 grain projectiles that gets to 1200 fps is Accurate #9. It is true that others are getting to 120+ but all of them will exceed book data by, in some cases, a wide margin.

Accurate and Speer both published data for FMJs in prior editions. Speer no longer does because they do not make that bullet weight. Accurate has also consolidated much of their data and only publish the more conservative numbers for XTPs.

Speer's max for an FMJ was 14.0. 13.5 was Accurate's max. CCI 300 primers for both.

13.8 gr behind a WFNGC hardcast bullet just gets past 1200 fps (CCI 350). Pressure signs are better than what i was seeing with 800-X at 1150. The Hornady max for A9 and a 200 gr XTP or fmj is 13.2. The recipe shows 1150, but it runs faster in my G20. I hit 1200 fps at a few tenths less than Hornady's max (WLP primers).

No powder meters better than #9. That being said, I still hand weigh anything at or near maxes. But for loads less than max, I am confident in the consistent weights measured through my uniflow.

The usual disclaimers apply. Please do your own careful workups starting with manufacturers' suggested starting charge weights.

why are people using magnum primers with such heavy slugs?

why are people using magnum primers with such heavy slugs?

My decision to go with a mag primer for the 200report grain WFNGC hardcast bullet and A9 powder was based upon my experience with other loads that were published for #9a that called foe a mag primer. I went ahead with a mag primer more of an extension of what had worked before. Lately I am coming to the conclusion that mag primers are not needed with A9 and heavy bullets.

I don't use mag primers for any other powders for 10mm.

Not so much because of the heavy slugs to use "Magnum Primers", it is more the compressed and dense powder types & charges trying to get all of the powder ignited and burned from these shorter barrels to provide the performance. :supergrin:

 

[Any Cal.]

In some of my loads the mag primers give a lot less velocity deviation than the WLP, at least in the limited # of rds I was working with.

I would try Longshot, Blue Dot, and 800-X. Longshot meters VERY well, Blue Dot, pretty well, and 800-X must be hand-weighed, but will give the best velocity. I've gotten 200gr bullets to 1150fps in my G29 with 800-X, and I had plenty of room to spare. I have never really pushed the 200gr bullets. I'm sure 1200fps would be safe and easy with 800-X.

THE BELOW LOAD IS WAY OFF-BOOK, BE CAREFUL!!!!!!!!
Let's not forget about Mike Willard's 200gr XTP/fully supported chamber load. That one pushed a 200gr XTP to 1350fps! His load was 10.0gr Longshot, standard primers, COAL 1.250". If I remember correctly, that load tested right at 40,000psi. It would stand to reason that about 9.0gr would get you there, and still be safe.

9.0 of Longshot did get me there. 10 shots averaged 1215 fps.

BUT, I'm getting some pretty big smiley's with 9.0...more than I'm comfortable with. I think I'm going to back it down to 8.8, which I think will get me 1175 - 1180 fps, and be safe.

Was your run of 9.0gr LS from a STOCK bbl?

 

[TRaGiK]

First post, first sentence...a stock Glock 20.

So yes, that includes the barrel.

Ah, sorry. Got distracted for a min there

Tested some loads yesterday , air temp upper 20's stock G20 brl, 22# spring. 9.4 B-Dot, 200gr. XTP 1.260 oal, 5 shot avg. 1160fps.

Sounds like a good load there. I tested the 200 XTP at a similar velocity by shooting at water-filled gallon milk jugs. It went through 5 and kept going with the first couple jugs absolutely destroyed. I have run them a bit faster, but this would no doubt be an effective round.

How did it group for you?
