158gr LSWCHP +p (FBI load) duplication.

[98 220 swift]

I am using this load for CCW in my LCR. I am trying to dupilacte it with reloads for practice use. What are some good choices? Best I have found so far has been 6.0 gr power pistol at a little over 1000fps in the alliant manual. Hornady also show 6.0 grs with a xtp.

I have run that Alliant load (Speer manual has the same). Speer 158 LSWCHP did just under 1,000 from a 4" Model 64. I usually load 5.8 gr PP for 944 from that gun. Hits POA with the fixed sights.

Best I have found so far has been 6.0 gr power pistol at a little over 1000fps.

This is the Speer #14 max too. And I have loaded this exact round with a Speer swaged LSWCHP. Through my Smith 67 w/ 4" bbl; it yields an average velocity of 962 f/s.

CAUTION: The following post includes loading data beyond or not covered by currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The Firing Line, nor the staff of TFL assume any liability for any damage or injury resulting from use of this information.

Strictly for the purpose of having a +P+ recipe handy for my K-frame, I have loaded beyond the Speer published max with Power Pistol to yield an average velocity of 1057 f/s - a 20% increase in kinetic energy over the published max. At which point, I was satisfied with the performance and ceased working up - there were no signs of excessive pressure. I will not specify the charge weight. And I do not in any way recommend other handloaders attempting the same. My Smith 67 is new and sturdy. I will never shoot this recipe in my J-frame Model 60 (even though some J-frames are chambered for 357 Magnum; and this load recipe is under magnum max pressures, with little doubt). For that matter, I will likely never shoot the recipe in my K-frame again - barring extraordinary circumstances.

I would say that the old "FBI load" was reasonably emulated with my work up. That said, IMO, the published max 6.0gns is a plenty stout round. Properly placed, it's gonna neutralize most any target.

Have any of you tried the Magnus swaged 158 LSWC-HP?
It's a lot better looking bullet than the Speer or Hornady. Sharp clean edges, a bigger nose and a bigger 2 stage hollow point. I have no means of doing a realistic test, so I was wondering if anyone had.

"Have any of you tried the Magnus swaged 158 LSWC-HP?"

Yes, I have. Those will expand at 4" 38 SP velocities and give about 6" of penetration in wet newsprint. I think I used AA#5 for the 38 loads but not 100% sure. Accurate enough for use on groundhogs out to 25 yards.

Cool, thanks, I thought that looked like a good bullet. I think I'll load some up for my carbine and aim for 1,100 fps in magnum brass.

[Mobuck]

Just my opinion but I wouldn't go much higher than 1100fps. Pretty soft so might lead badly in a rifle. I'd also expect extreme expansion since my loads were in the 875-900 range and expansion was around 0.50-0.60".

Pretty soft so might lead badly in a rifle.

I didn't mention it in my first post. . . But the Speer soft swaged LSWCHP at 1057 f/s leads up the barrel something fierce. After just 30 rounds, there was easily visible lead throughout the entire length of the barrel.

But when I did my workup, leading was not a consideration at all. It's about neutralizing the BG first; worry about barrel leading later.

I use liquid alox on all my swaged bullets, no problems with leading.
