Longshot in new Starline brass under 140gr Lehigh Penatrators and 200gr XTP's, 140's run 1550, 200's go a very easy 1200 fps.

I agree about Titegroup. I like it for 9mm and 380 practice loads, but wouldn't care to use it in the 10. In the late '80s when we were shooting a lot of 10mm we had great success with Accurate No's 5 & 7, but No. 2 (similar burn rate to TG) just seemed to be too fast. These were all the original Accurate powders, not quite the same as today's.

Finally getting around to loading. Curious about this load I can't find any published data over about 8 grains of longshot. Wonder if this is a bit hot?

8.2 grains of Longshot is the max for a 200 grain bullet, per my newest Hodgdon annual.

I load that with 200 grain gold dots with good results.

I use BD in cast 220 gr loads with no issues so far in a Glock 20 and Springfield XDM 10MM for practice Buffalo Bore load I carry in Alaska


Blue Dot warning

What load manual did you get that from?

And yet, Alliant currently lists BlueDot for 110 and 140 grain bullets. Lots of speculation about this 13-year-old “warning”, while thousands of folks have used the powder for 125-grain loads…..


.

Various readings on websites, as to starting point, than just worked it up in my gun, watching for pressure signs, ie smiles on brass, flattening of primers, going to keep reloading the same 30 pieces of brass, so I can see how long they will last

I have overloaded the 10mm with many powders in work ups.... until the brass failed.

If you read the published data, you might think LONGSHOT is going to produce a lot of velocity.
But real testing shows it is a dead end.

The most power I can get is from 800X.
But this takes many steps to compress the flakes in the case.

The most power that is easy is with Power Pistol.....Not longshot, not Blue Dot, not Enforcer , not AA#9, not N105, not 3N37,

ClarkM?

What do you consider max load or velocity (whichever you are comfortable quoting) with Longshot and a 180 XTP or 200 gr cast?

Same question with Power Pistol?

I am shooting a Kimber 1911 if that makes a difference.

LOL! i shoot a Dan Wesson 5" 1911 10mm, just yesterday i loaded 200gr Hardcast bullets to 1256 fps over 8.5gr Longshot, 22 bhn alloy, 0.300" meplat, H-Tek coated, run like greased glass with 1.240" col, 8.5gr Longsot also gives 1241 fps with 200gr XTP's, if i needed a 41 Magnum i'd buy one, i think these loads are absolute safe max power in the 10mm 1911 platform, and more accurate than i'll ever be.

That is about what I expect from Longshot. But I have not passed 1100 yet. And yes, I own several 41 mags.

You bet I.S. i'll be interested to see what numbers Clark puts up, i'm happy as a hog knee deep in corn chops right where i'm at.

180 gr XTP
AA#9 14.7 gr gives me 1240 fps in the Springfield I rebuilt
Works great on hogs

200 Hard Cast wide flat nose bullets
10.3 grains of N105
Win brass

1,300 fps out of G20
