Thanks again guys. I appreciate the help

The problem is solved. It was the concave end of the seating die hitting the bullet at different angles. I reversed the seating rod to the flat end and...

This is why I don't like to share load data. If I can I tell the source I use and let them find the numbers.
Boy did I screw up here. My numbers are a bit off. The target was 1.360"...

Ok just went to the bench and loaded 10 rounds to see if there was better consistency when I turned the seating rod around and used the flat side rather than the concave. Out of the 10 rounds all...

Yes that is what i am thinking also. Maybe turning the rod around will help. Maybe there is a better seater for this cartridge? Idono

Thanks guys

Let me answer the questions

I am using both the tip of the bullet and a comparator. They both indicate the COAL is wrong or inconsistent. I just loaded some other caliber ammo and...

I am trying to load some tok 7.62x25 ammo. I am using PC cast boolits. I am using the Lee dies for the Tok. I can not get consistent seating depths. I am trying to get 1.360 COAL. My lengths...

Thanks guys

Let me see if I can answer all your questions.

Bullets are sized to .309

I have not slugged the barrel. Now I am only able to get the OACL to 1.955. These boolits are short. I...

10.5 inch AR upper. Just not happy with the accuracy. Inconsistent groups 3" plus with flyers @ 50yds

Trying to find a load using 115 pc cast boolits. I've tried 4227 and 296. Neither one produces acceptable results for me. Anyone have different powder suggestions that work for them?

thanks

Ha, thanks LOL. I went ahead and loaded some to the 1.810 COAL. That was the problem. They would not function in the firearm. I then lengthen the COAL to 1.850-5 and that seemed to do the trick. ...

lar45 and others

Just got around to loading some of the PC bullets. These are 115gr PC bullets. I am starting with 15.5gr of IMR4227. This seems to get pretty close t the bottom of the neck of...

Hey thanks for the help and the time to help me out. I have a few of the powders you have numbers for. I will go lite and work up. Thanks. It looks like the PC it working. I had to...

Ok gonna take the chicken way out. Im reasonably comfortable loading PC bullets, not lubed. I decided to put the lubed bullets into the PC oven and get the lube off. Then roll the bullets in a...

Thanks The barrel length is 10.5" Plain base bullets no checks. I have used 16gr ish using 4227 with PC bullets so 15.5 seems reasonable. I very well may just chalk it up stupidity and have him...

Thanks guys everything helps still cant find any data

Ok these are 309 boolits. They cast and are only lubed in the lube grove.

The length of the bullet is .675

The COAL is 1.810....

Obviously I meant Boolits. I hate spell checks.

Anyway yes I agree. It would be best to just use them the way they are but we can't find any load data for them.

Is there a general rule of...

My buddy was going to buy some PC .308 boolits for his 300 blackout. He picked up some uncoated cast but they were lubed.
Two questions.
1. We can't find any load info for these bullets. I...

Ill try that one also. Have a bunch of 296 around.

After much playing around getting magazines that work I had some pretty good results with the 300BO. Very very long story but so far the pmag gen 3 seem to work without mods. The gen1 with mods...

Interesting day today. Got out to try a couple of mags with my son in law. Three different pistols two different magazines. Two different calibers.

I took the, what I think is a, gen1 pmag out...

Thanks you I did not find that one.

Ok let me ask ya this. The Lancer mags. I see Midway says the Lancer mags are compatible with a bunch of calibers including 556 and 300 bo. Does Lancer make a specific mag just for the 300bo. ...

Good, the Pmags I have are just the 556 mags not the 300 blk. I only sacrificed one to try it. There are two places that may nave the Lancers reasonably local. If so I may pick one up to hold me...

Thanks guys. I am loading 4227 15.8 grains. Its a pistol gas system. Not sure about holding open with only one round. I do know at least once the bolt did not hold open on the last round. That...

Thanks I have a couple of the Lancer Warfighter mags on the way. I did a little more work on the pmag I think it may be better but it really isn't right. Only way to tell is to take it out and see...
