160 Grain SWC cast lead bullet

First topic message reminder :

Colt Government model, tapered rib, Ultradot 30mm.
19lb mainspring,10 lb recoil spring, 6 lb magazine spring, standard firing pin spring.

I have been trying to work a decent load up for these new light bullets, no ransom testing just off my inexperienced hand and paying attention to the slide cycle.
Accuracy seems off and ejection seems weak with 4.1 WST, accuracy gets better as you go up but seems real good and cycle is good at a high of 4.8 WST.
tested 4.1 to 4.8 30 rounds each.

The recoil did not seem to increase as the powder volume went up ?

Anyone else fooled with these little 160 G button type SWC ? 4,8G seems a bit high ?

Avg 796 fps with 4.4 wst, .925 shoulder to base dimensions . probably a .463-.465 crimp

Same POI at 25 yards.

James, is that crimp dimension correct ?

Yep.

at some point I've got to clear my head, start using 

what the Masters are finding success with....

I looked at pet loads and saw Mc Dan had said 4.4 of BE.  IS 4.3 the better?  Loading up some today

4.4BE is the most I would use

4.3-4.4, somewhere in there my disc measure drops. Depends on temperature, humidity, etc

We're not shooting rifle distances..

Thanks gents

For the long line regardless of powder used a good starting place with the 160gr S242 is whatever charge one would use with a 185 JHP like the Nosler or Zero . Like 4.5 BE , 4.8 WST , 4.3 N-310 etc. Short line 4.2 - 4.3grs of BE or WST will work . As always depend on way gun is setup & what it likes , groups will tell .

Tried 4.3 be with the 160s today. Held the 10 ring at 50 yards. I wonder if I spiced the up a bit

4.0 BE was nice at 753 fps

No one is talking about primers with WST, l understand they are critical.

I got big velo spreads, puffers and bangers with Federal and 4.5 wst

I also tried wst and using fed primers, groups nowhere near as good as than with the BE

I run Winchester primers with WST .. no issues ever

Greetings,

Long ago, I tried WST with the H&G #S242 bullet (160 grain) and had velocity spreads over 100 FPS.

I went back to Bullseye powder.

On the plus side, WST worked well with both the H&G 68 (200 grain) and H&G 78 (215 grain) bullet. Groups were well inside the ten-ring at 50 yards with my 625-4 revolver.

Ooops, could not find the H&G 68 with WST targets...

It seemed as if WST favored a heavy bullet?

Cheers,

Dave

12 shot groups fired via the Random rest.

Think gave me last round not ejecting.  4.4 seems pretty accurate. 4.3was as well
