What weight recoil spring do you run Mr. W?

My 85C only ejects cases loaded with 4.1gr of VIT at 1.14 with Berry's 124gr HBRN about 3 or 4 feet with a 12lb CGW recoil spring.

I guess I should try an 11 lb spring or shorten them up a little.

Buddies that used them in stock sprung guns had them landing at their feet.

My spring is supposed to be a 12# version from Wolff Spring.

At 1.135 with 4.1  at 129 PF and an 11-12#  (can't remember which now :-[) spring, I get good ejections with the 124 HBRN.

That would make sense, knowing that these Armscore jackets are harder than Berry Mfg's plated. More energy absorbed getting the bullet down the barrel, less energy available for the slide. But only a small amount, detectable only with a chrono or by watching the flying brass.

Nice Wobbly!

You may recall my thread(s) discussing WSF a while back, and I can tell you now that I shoot it exclusively in my action pistol loads. I am bleep near through an 8lb keg of between my daughters boyfriend and I loading nearly 600 rounds a week of the stuff.

I absolutely love it for cleanliness, decent recoil and ease of metering through my Dillon measure. I must have over 8000 rounds loaded, fired or stored using WSF at this point.  At least 3750 of were loaded using those Montana Gold 124 JHP's you show in one of the pics up above.

My only question is what gun are you shooting them through to get an OAL of 1.130 ? Those things will hit the lands on my SP01's @ 1.095" so I loaded them @ 1.080"...   They are great bullets, but need to be loaded short to work in any of the CZ's I have loaded them for.

On a final note, my go to load for WSF is 4.6gr over a 124/125 gr. JHP. They chrono right at 1100 fps for me.  I have been shooting X-treme's, Zero's and those MG's for the last couple months. I like them all really but the Zero's are probably the nicest so far. I have been experimenting with 147 grainers over 4.2gr's of WSF and been pretty happy. I love the slightly reduced recoil impulse when shooting the 147's .

Mr Loo -
Welcome back. Glad to hear you're getting on well with the reloading.

I wasn't shooting MG, it was a look-alike bullet from Armscore. I'm shooting them in my SP-01. Glad to have the OAL info though.

 ;)
