hodgdon longshot

Postby jlinzer » Sun Mar 03, 2019 2:59 am

Hi, does anyone have any experience using longshot for 450 bushmaster? It doesnt look too far off on powder speed chart from lil gun or h110. I've had pretty good luck with it in medium power 44 mag and 357 mag, works really well in 10 mm and 40 S&W. Appreciate any feedback. J

Welcome Aboard OM.

Though they have close densities, that's where the similarity ends in the 450b.

Based on a 250 gr FTX at 2.26 COL, here's how they compare.

21gr Longshot = (50% fill) = 33.6k psi (near max recommended)
21gr Lil Gun (48% fill) = 9.5k psi (hardly even getting going)

To put that into a more realistic perspective lets look at a recommended charge of Lil Gun vs LongShot:

37gr Lil Gun (85% fill) = 35.1k psi (typical load used by members)
37gr Longshot (88% fill) = 115.3k psi (KABOOM!)

Longshot IMHO is not a powder you want to use in this caliber.

Thanks Hoot. Its interesting based on my (I'm sure very crude) estimates and experience with longshot, I was figuring somewhere around 18 gr as starting load with 250 gr FTX. Curious as to the source of the pressures you mention, was this from software? Appreciate the feedback and welcome. J

Its from a pretty good modeling program called QuickLoad. Like most fast pistol powders, Longshot has a much higher Rate of Explosion than slower pistol powders intended for magnum calibers.When combined with energy content and burn rate, this contributes to How Much / How Fast the chemical power is delivered. From that group you move into shotgun powders (still pretty fast) and finally into rifle powders which run the gamut from fast to slow. Most reloading manuals have a section in the beginning of the book, which describes the entire reaction.

18 gr longshot with 250 rainier plated gave about 1700 fps out of 16" ruger american. Pretty consistent, 3 shots measured with chronograph, 1683 fps, 1684, 1678. 210 gr .452 blue bullets (for pistols) with 18 gr longshot gave 1734, 1741, and 1745. Very accurate short range however groups opened to about 6 " at 100 yds. Maybe not stabilizing these odd shaped bullets. I have not tested rainer for accuracy yet. no signs of probs so ill try increasing charge, I suspect 2000 fps should be achievable without pressure issues but need to be careful as I cant find much if any information on longshot and 450 BM.

Winchester production (i think X450DS) and remington production (260 gr accutip) production were near ragged holes at 100 yds. remington impact was 3 " lower to the left. Chronograph of the winchester was right what they report on the box, 2200 fps. For the price its worth trying to pick one of the ruger americans up IMO, the one i have seems to be very accurate. I think maybe longshot is worth doing more testing with. It works well in 10 mm, 9x25 dillon and decent for medium power 357 mag so I like to keep it around. It meters well, seems to be versatile so its one of my few "if i only had one" powders.

I think rainier plated were disintegrating at near 100 yds, no holes in target and looked like birdshot hit the dirt berm.

Good accuracy with hornady 230 gr HAP near ~ 1" at 100 yds with ruger american no pressure signs using 20 gr longshot. Seems to be good cheap plinking load. Did not check velocity but I would guess near 1900 fps.

yeah plated bullets never been good for many of us in the 450. You were doing good with those HAP bullets and 1", best I could get any FMJ style bullet was 1 1/2" which was plenty fine for plinking for me.

you're running them too fast. they're not designed for that kinda velocity. those are LC bullets meant to run around 1200 or so and - from what i can find - a max recommended at 1500 Fps. not terribly shocking that they're coming apart at near 1700 fps

from rainier's website

from midway's page where the bullets are sold

id imagine you could back them down some more and have a cheap cowboy action style plinking load, but for only a few pennies more per projo - you can get 225 FTX blems and run them with a standard load and not really worry about them going to peices.

My first experiment for the 2019 comfortable shooting season will be 200gr Speer TMJ Semi WC around 2500fps. Will be interesting to see if they hold up. Bought them for plinking with my 1911 and got the idea of seeing what they'll do out of the 450b. QuickLoad says they're a perfect match up for Lil Gun in the 450b. Of course this coming weekend is calling for rain/snow mix! :roll:

Let us know how it goes. For some reason I expected the rainier might hold up and if it didnt i would have thought it would come apart much closer then 100 yds. Ive only read about this kind of thing happening but as you guys point they were not designed for these velocities. im guessing the way the impact looked the rainier were coming apart consistently very close to 100 yds, maybe 90 yds.

Whats interesting is the blue bullet 200 gr SWC seemed to hold up out to 100 yds at least, i think it was ok further too but accuracy was not good. They did seem promising at 50 yds. I would guess if I backed down the velocity I might see better accuracy at longer range but I sort of was hoping to see at least over 1800 fps.
