Spring Question~~
Okay... I'm really tired of my Beretta 96 throwing brass 20 feet, and I've heard that light springs can damage your frame. This gun has a steel slide and aluminum alloy frame.
I'm shooting 165Gr JHPs with 6.7 grains of unique for around 1100 FPS. Thats not the only load, but I am basically all shooting that pressure and velocity.
Stock is a 13lb spring... I can go from 8-20 lbs. I've posted this on another forum, but nobody has replied... springs must be really mysterious. TIA

Are the springs expensive? Just get a few heavier springs and try progressively stronger until it stops feeding or malfunctions then back off. If you are using hot loads a normal load may not feed. You can also change the point in the stroke where the brass kicks out. Experimentation is fun just as long as it is reversible.
Try a JSP for more reliable expansion at lower velocities.

This place should have springs for it. You can call them and ask also. That is a pretty hot load.

The springs are $7.50 a piece...
I might just have to experiment...
You can go pretty hot on .40 Smith as long as you aren't using a Glock...
I'm shooting long range silhouettes so I need the velocity.

You can purchase cool little nets that attach to your pistol and catch the brass. A friend of mine made his own for his pistols and AR's and other semi-autos. They work great and he hasn't lost a shell in months. And we don't all have to watch where they're going and pick em up before they get lost. With a little bit of stout wire, you can make the frame, buy some netting material and have one of your numerous girlfriends .. or mom ... sew the bag to fit the framework. You attach the whole works with some velcro and ta da! No more lost brass and shoot whatever load you desire.

I will never forgive or forget a model 94 Winchester chambered in .44 mag I had that tended to trap brass in the spring! It also dumped the magazine under the feed ramp at one point - instant closed range!

T1, man I almost blew soda on the moniter again. I have had dumb stuff like that happen before, once was brake clean that somehow went between my hat brim and glasses.
A friend of mine was shooting a handgun at home, I forget what it was exactly, but he was trying to do it movie style, with the gun at an angle. When the shell was ejected, it came back and nailed him in the forehead right between his eyebrows. I wish I had it on film, the look on his was hilarious, I think he thought he was shot or something.
To get myself back on track, the spring is too weak for that hot of a load. I had similar issues with my SKS when I fired it with 160 grain loads, it made a double kick, you would feel the initial kick, then a really hard hit when the slide hit the stop.

Drinking soda while cruising FTE can be dangerous to all kinds of electronic lifeforms..
Sometimes a small modification to the point that kicks the brass out can also affect the velocity that the brass is thrown. The farther back from the chamber that the brass kicks out the slower the slide is moving. Of course if the point is too far back a stovepipe jam is possible. Gunsmiths probably have a name for that part but I aren't one... I have just messed with a few firearms over the years.

You really don't want to mess with the ejector on a .40 Smith, or any handgun... A lot ofcartridges headspace on that ejector rod, they headspace on the mouth too....but I've seen pretty generous chambers compared to ejector rods...They are cut to fit precisely in the recesses of the case head.
My buddies SKS throws brass pretty far, but its an SKS and you can't reload the stuff he shoots anyway...

I see what you mean....
Right now the ejector pin is angled, it fits through a slot in the bolt, as most semi autos do. I think that modifying that piece may cause it to hang up.
I think I'm just gonna have to order a couple spring sets and try them out...
