9mm accuracy

[Nick2010]

I have a 9mm shooting 124 grain cast bullets. i don't think it is shooting very accuratly, what are some places to start to improve that? new to reloading pistol rounds a little.

[BulletFactory]

Is it leading?

[mpmarty]

If it isn't leading and or keyholing then just keep on keeping on. Practice!!!

[Nick2010]

its not leading, i'll just keep shooting then!

[ph4570]

What sort of accuracy are you seeing with cast? Do you have a jacketed accuracy comparison? The "is it leading" question/answer is a good place to start.

I was vexed with the 9 and cast boolits for a time but have a good combo now and accuracy is good with zero leading -- Lee 120 gr TC, felix lube, 0.002 over bore and Blue Dot.

[BulletFactory]

You can try different lubes, what are you using?

[atr]

get an MP40....then accuracy is not the issue,,,just how much lead you can spray the area with

[z4lunch]

Steve here... I have an as new Glock 22. I bought a KKM 9mm barrel to shoot cast.
I have been shooting an old ideal 356402 Here is a pic at 25yds off hand 25f and windy.
2.9 of Bullseye...they dam near roll out the top of the pistol

You don't think it's shooting very accurately.

Well that tells me nothing.

How about you take that 9mm, step off a known range, and fire a known number of rounds at the same point of aim on the same target.

Measure the largest distance between the impacts, and report back.

We can't tell you anything without quantifiers.

And what "accurate" is is such a subjective term.

Give us more information and we JUST MAY be able to help you out.

[waksupi]

Use different amounts of powder, and different powders. Don't just load up a cook book load, and expect it to be the best.

[noylj]

Size and sort your brass by length. The best accuracy is with those few cases that are 0.750" or longer.
Since you aren't complaining about leading, then I can assume you have slugged your barrel and are uing bullets that are at least 0.001" over groove diameter.
If you are shooting L-RN, I have not found them to be very accurate. The most accurate bullets I have found are the 115gn L-SWC and 124gn L-SWC from SAECO. I would like to try the Lyman 148gn bullet some day.
Finally, there are very few 9x19 pistols that are designed for accuracy. Simply keeping them in an 8" circle at 25 yards is asking a lot of them and, in most cases of poor accuracy, the person behind the trigger is the problem.

[Nick2010]

alright thanks for all the help, it seems alot of you guys were able to lead me somewhere if the information i supplied and it helped. i have tried a few different loads, but its probably 18" circle at 20 yards or so, was hoping for a little better, ill probably load couple hundred more rounds and keep shooting these same loads and get myself some more practice in.

Thanks guys.

Try squeezing the trigger , not jerking it.

[BulletFactory]

Thought this might be useful here, if you haven't seen it.

First buy some factory and shoot it at 15 or 225 yards. That is the standard yo want to get to. You can vary velocity, hardness and boolit bearing surfaces as well as lube. Fire into a recovery tank or box and examine your bullet. Is the rifiling even and not showing signs of slipping or sliding? Try it from 850 fps to 1200 frs and see what changes.

[BulletFactory]

225 yards with a 9, not too shabby.

[Doby45]

Pfffttt, I do that all the time.. WITH MY EYES CLOSED!! Never said I hit anything.

Hmmmmm, let's see now. It's 10:36 in the evening. That is about 6-8 beer for me. Maybe a shot or two to boot. I just might be up to thinking about a few 225 yd shots with one of my nine's too. :kidding:

Just joking, I know it's a Typo. Good info too. See what factory rounds do then either duplicate that accuracy or get better with cast.
As already mentioned. The first load in the book you try may not be and usually isn't the most accurate load. Different powders and charge weights of each will help tell the story.

[reloader28]

You guys must be alot better than me.
I cant shoot pistols out to 225yds.
Anything past 200yds and my groups open up to 2 or 3 inches.
:kidding: :Fire:

[BulletFactory]

lazer pistols maybe. ;) guaranteed not to lead the bore.

[dverna]

First - clean the barrel and shoot factory jacketed rounds off a rest. Try a few different types to get a feel for what the gun will do. If you get a pattern, have a good shot fire it to make sure it is not you.

Then reload some factory jacketed bullets and see if you can match factory ammo.

Lastly, - clean the barrel again and load up some commercial lead bullets (good ones like Dardas, LaserCast) and see what the gun will do with a "good" cast bullet.

It is not rocket science. But you need a "base point".

Eliminate the gun, your ability to hold the gun and fire the shot, your reloading technique and lastly the bullets.

That is laughable..

One basic key I have found with the 9MM is to size your boolits .357 as a minimum. Sizing the 356402 boolit to .356 had boolits tumbling in all my 9MM pistols at ranges as close as 5 yards. 4.1 gr of Win 231 works quite well with this boolit through all my 9MM handguns and is more accurate than I can hold.

Thats not a typo................ several nines have tangent sights to 250 or so. I've shot Canadian Hi-powers with the tangent sights and shoulder stocks. Lead loads held accuracy to about 300 yards.... enough to hit a man anyway. Some nines are very accurate and some aren't. Finish Suomis have sights marked to 600 meters.

[robertbank]

Yes if your gun is sighted in at 25 yards the holdover at 200 is in the neighbourhood of 64" @1100fps. Doable I guess.:D

You don't do "holdover" for long range pistol shooting, you hold up some of the front sight.

Critical basic technique issue.

Good to know the boolit still drops 64" no matter the technique. I have a Red Dot on my carbine so I have to use the guess method.

You guys are missing a critical and often overlooked point...how to throw the gun when it's empty. I've seen it done many times so I know it's important to work on that too. But 225 yds. is quite a toss, might just throw your arm out. If a guy can hit a man sized target at 25 yds. that's good accuracy and a good throw in my book.

[Love Life]

All jokes aside just practice your shooting. I have the cast 9mm down to an artform in my Glocks. Shoots great groups at 25 yards (I think that distance is retarded for self defense practice) and even better groups at the 10 to 15 yard range. Definately MOH (Minute of heart) on all the targets I shoot. An 18 inch pattern isn't the best, but is still tight enough to lay most men low. remember the average shoulder width of the western male is 24 inches. I think what I am really trying to say is don't get wrapped around the axle of the one hole group. If you can hit a fist sized target at reasonable distance than you are good. Hell I would rather have my rounds go in different holes when entering a body to cause more shock. Why do you think the hammered and controled pair are taught along with the Mozambique/failure to stop drills?
