What velocity were you looking for with a 148LWC

I have shot a bunch of 148 LWC's in the 38 Special, with 2.7 grains Bullseye. Heard it was a standard load but I never shot it at 50 yards for accuracy. It shot "well" at 35 yards, but I was not shooting on paper, and I was not target shooting when I used this load. Now I am curious,

I do see that factory ammunition went 810 fps out of my Colt Police Positive which is faster than my loads. Anyway for accuracy and stability at 50 yards, how fast should a 148 LWC be going?

Wow, that's kind of high from Zero. The other classic load is 2.7-700x

Velocity high 6, to low 700s. That's for HBWC. Is that what you're referring to? Solids can go faster without issues; there is no skirt to blow off the head.

I chronographed the following loads out of a 10 inch Contender
700X: 2.5 & 2.8.   Velocity 787, 837.
Bullseye: 2.7 & 3.0.  Velocity 783, 841
Red Dot. 2.9 & 3.1. Velocity 879, 900.  DO NOT USE THE 3.1 LOAD!  

Of these the most accurate were 2.7 Bullseye, 2.9 Red Dot and 2.8 Win 452AA which gave a velocity of 788.

Drop these velocities 50-75 fps for a 5 inch barrel.  

The 3,1 load of Red Dot is over SAAMI max pressure for+P.  That powder is very touchy in 38 special.

With which bullet? HBWC or solid? Thanks

I have been using solid core.

Been a long time since 452AA been available. I think I shot up my last can in the 1980's!

So, you think the solid LWC would be accurate and stable at 50 yards going 750-760 out of a six inch tube?

The only other powder I might use with this bullet is Titegroup. And if my 45ACP experience is similar, I don't expect much, if any, powder grains difference between Titegroup and Bullseye Pistol. Considering the number of kegs of Bullseye I have, a Titegroup test would just be for the pursuit of knowledge.

TBH, I don’t really know the accuracy differential between solids and HB.  My guess is that, at 50 a solid cast might cost points and Xs but no more that a couple of points and maybe half your normal x count.  Otherwise I’d find another bullet.  

I forgot to mention the ammo I shot was all Speer HBWC.

452AA is legit. "Some people" still shoot it to great effect.

If I remember correctly, 2.7gr BE Magnus 148 hbwc from 6” Clark long slide 38 gave me 735 ish. I’ve shot 100 on long line with this load.

They spec Remington HBWC target ammo at 710fps
