45ACP and rifle questions

[kestak]

Greetings,

I have 2 completely unrelated questions for you guys.

1 - Any of you have issues feeding a 1911 (here it is a RIA 1911A2) with Gold dots 230 grains bullets? I thought I solved the issue when I changed a little bit the angle of the ramp (The barrel is not ramped. It is the frame) but I still have the round beeing stuck parallel to the slide (It does not climb the ramp). Anyone could recommend me self-defense bullets or manufactured rounds that would climb the ramp? What about those bullets who are hollow points but they have an insert that make them round nose?

2 - Bear with me here. I reloaded some 30-06 and shooting them made me think...:banghead:
Yes, Me thinking is never good...hehehehe
Here is my question: At the moment I press the trigger and the firing pin is hitting the primer. The powder ignite and propulse the bullet down the barrel. When the gun does begin to move? Is it at the exact moment the powder ignite or just a little bit after the bullet exit? I am wondering that because if the gun begins to move at the moment the powder ignite and pushes the bullet, how come it does not affect the precision each time the gun is shot?
I would imagine the "vibration" would move the barrel a little bit out of where the "cross" of the scope points and the bullet would not hit exactly where you pointed...Anyone knows why the bullet hit where we point if there is movement while the bullet is into the barrel?


Thank you

"...the round being stuck parallel..." Sounds like a mag issue to me. Isn't releasing the cartridge properly. They angled up when in the mag?
"...the exact moment the powder ignite..." Yep. The pressure starts building then and goes in all directions.
"...how come it does not affect..." Think milliseconds. Plus a lot of forces resisting the pressure.

Recoil begins when the bullet starts to move.

I am wondering that because if the gun begins to move at the moment the powder ignite and pushes the bullet, how come it does not affect the precision each time the gun is shot?

It does indeed affect precision.

I would imagine the "vibration" would move the barrel a little bit out of where the "cross" of the scope points and the bullet would not hit exactly where you pointed...

You have it right, it seldom hits EXACTLY where you point.

Anyone knows why the bullet hit where we point if there is movement while the bullet is into the barrel?

Pure luck. That is why targets have scoring rings and benchrest shooters have micrometers to measure their groups. Accurate shooting is all about keeping the vibrations of gun (and shooter) as uniform as possible.

Throw a loaded round in the fire. It goes bang. What shoots out? The light case. The bullet is still in the fire.
More weight, more inertia. If this didn't work, we couldn't have semi-autos. Compare your gun weight to your bullet weight. One you can control in your hand and the other with blast through bodies. Both have the same forces working on them.
Your .45: you have a COL (OAL) problem or a magazine problem.
If you aren't a paid gunsmith, don't muck up your feed ramp.
A magazine is worth every dollar you spend on it. The most critical part of a semi-auto is the magazine. It is also the easiest to damage.
Others disagree, but the best I have found are Colt and Wilson. Of the Colt magazines, I haven't bought one in 15 years.

Greetings,

Anyone would be able to suggest a self-defense round that would feed in my 1911A2? ANyone has one and can get reliable feeding from any self-defense manufacturer?

Thank you
