160 Grain SWC cast lead bullet

Post by Multiracer on 6/24/2018, 6:27 pm

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 ?

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..

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 .
