Question on Setback

(1/3) > >>

thirtydaZe:
After reading an article from SFG in another thread, i had a question about setback, and how everyone who carries handles it.

I like to get to the range at least once a week.  I carry a shield .40, and like to shoot it on each outing, however i always switch ammo to the cheap stuff.

Essentially what happens, is i cycle the same 2 rounds of my SD ammo.  When i get to the range, the one in the chamber comes out, then when i leave, i cycle that next magazine round in, and put the one that just came out of the chamber back on top.

Well, i haven't measured either round yet, but seems likely that chambering after chambering would eventually set the bullet back.

What do you do, shoot one each time?  i almost hate to do that, as to keep the good stuff for an if needed situation, but i hate to have an over pressure situation too..

Actually, I have no friends and no life and nothing to do and my wife and dog ignore me, so I pass my days prowling the Forum and pouncing on Interesting Posts.

Anyhow:

Actually, it depends.

I've tried the recycling-the-rounds exercise many times and many times have gotten pretty much zero setback.   Both with my own reloads and factory ammo.   Using a mike to measure and all that.

And sometimes you do.

It depends.

Try it with your own mike and see wot's wot.

Now....If you ask me how much setback causes how much pressure increase in a given caliber, gotta refer you back to that article.   Which applies only to .40S&W, as I recall.

Happy reloading.

when i took my ccw class from 88 Jason the teacher said he did it one night on purpose, he showed up the round and after awhile it was a visable differnce

pretty crazy....

Dan W:
Setback problems are the reason I don't own a 40...way to sensitive to anything that increases the pressure.  9mm and .45ACP don't have nearly the problem with setback related kabooms


I deal with setback by keeping my EDC gun fully loaded 24/7/365, so even with practice and cleaning the chamber round doesn't meet that many feed ramps

I keep the rounds that have been chambered in a separate container and shoot them during practice sessions. I practice mostly with reloads but want to use my regular carry rounds enough to know reliability, recoil, accuracy  muzzle flash and etc.
