Real Accuracy (2 moa or less) with Coated Rifle Bullets at 1800 fps or greater.

[Beau Cassidy]

ESPC on the bullets or another method of application of the powder coat? It would be interesting to see the differences in coated gascheck bases versus non-coated.

[KYShooter73]

ESPC, tapping a washer on the gas check shank so I don't get PC on it and my checks will still fit. If my alloying skills didn't suck, I would love to put heat behind my .308.

In the 308, I loaded 5 each with 24, 24.2, 24.4, 24.6, 24.8, and 25gr. of 5744 with the NOE 311365

here are the best two





My next outing will be 25-26gr

Mike Hughes:

Good looking groups. All of your posted groups seem to be staying relatively at the same size as you increase powder/velocity. It will be interesting to see if your groups remain tight as you increase past the 2000FPS region. I have the 311365 and am following your testing, please keep us posted.

I realize these do not compare to jacketed, I am just having fun and sharing my results.

What is your COL? In my Rem.700 I can only seat them out to 2.830" before hitting the rifling. This puts the GC well below the case neck.

At 25.4 groups started to open up. At 26 grains, it looks like it may be trying tighten back up. Lyman shows 27 gr as max potential load for the 311299 which is about the same weight boolit. I will see what happens in the 26-27 range.

The sun was at a bad angle and the chronograph missed some readings

I also loaded some Rx7, varget, and Imr4227
The Rx7 looks like it has potential at 28 gr. Varget grouped decent with 34 gr @2175fps. The 4227 really caught my attention with 22, 24, and 26gr all shooting good. The lone hole on the 22gr target was a cold barrel shot. Most of my pc loads have not been affected by barrel temp. Also, the 4227 was extremely quiet fired through the suppressor.

My COAL is 2.80, longest that ar mag will hold. At 2.80, I was into the rifling (I am sizing the nose to .306 allowing to seat longer. I no longer worry about gas check below the neck, I am installing gas check before coating. This sets the check in place almost as if it were welded on. these pics are after attempting to pry off with a screwdriver.

Hi all,
I have been reading and casting on and off for quite some time now. I am also interested in PC boolits, mainly for my .458WinMag. This is a Ruger M11MKII. Nice rifle, but peculiar...It does not like cast boolits, no matter what I throw at it, weight, powder, gas checks combinations.

It just tumbles the bullets as if I was throwing them by hand. About 2yrs ago, I came across Lead Cast and coated bullets here in Australia, namely Westcasting. These have a golden coating which is very tough and the company markets them as being able to sustain >2000fps velocities.

However in order to achieve stable flight I had to gas-check them. Now the ones I am using have a weight of 405gr, plus GC +- 420gr. I have managed to get decent groupings using 66gr or Reloader 10x at 2100-2200fps chronographed. This is the most accurate load-out for this type of bullet in my rifle.

These boolits however do not have a recess for a gas check, but I place a drop of superglue in the GC cup and then size them through a Lee Sizer. No lube is needed as the coating is smooth enough. I will also post pics of bullet and target.

Apologies for the long post, but what I found is that these westcasting bullets have only 2 grooves. Boolits cast from a conventional mold have several and that. I think is causing the tumbling action. These however, together with a GC and sized to .458 (that's all I have) fly straight and give me excellent accuracy.

Coming to the point, I seriously thing that if we are to PC boolits, then we don't need more than 2 grooves. Possibly only one to crimp the boolit in the shell....Now who's gonna make me a mold with only the crimping groove???

Any of you guys thoughts??
Thanks, bosco

that's some fine looking groups there
hope to post some soon myself .. have many at 50yds .. but will wait till new backstop is built for 100 and get some submitted here

[bosco555]

I will be shooting this coming sunday and will bring back some targets. Some people also mentioned trying Reloader 7...Trying to find the right combination is a long and winding road to be sure...
THanks Popper..I wouldn't hold my breath about Oz. You get cr@p service here. Will give accurate a call/email and see what they can do...Interesting to see...

[bosco555]

Sorry guys, went shooting on the weekend, but it was darn hot here, and the results were horrible, it looked like I actually threw the boolits at the target by hand, so I ain't gonna post no targets here. Will have to wait for the weather to cool down a bit and I'll try again..However the few that ended on the paper grouped OK considering I was shooting off-hand, no rest or bag..

[Just Call Me...G]

Howdy Gents,

Today I spent some quality time reading this thread as well as a few others regarding PC of boolits.

I have also been following and have read most of the Hi-Tek thread which I check in on from time to time...no disrespect meant, but I refer to that thread as the "Hi-Tek Love-In". It just seems a bit much for me and it's the same posters, over-and-over again shouting from the rooftops about how phenomenal it is...ugh! /rant-off.

I just wanted to stop in and say THANK YOU! to Don Verna for getting this thread up and going and for really trying to get some information that is relevant.

As a .308AR shooter and a suppressor owner, I am especially grateful to Mike Hughes for posting all of that great and usable info.
I will be following this thread closely as I am and have been interested in these alternatives to lubing for rifle accuracy.

I look forward to seeing more posts and once I get set up with my own process I will be posting results as well.


Keep the High Ground,


G

looks like it has some good potential Popper

Going to need more testing to confirm but I started getting some really good looking accuracy with my 300BLK as well just the other day. Loading Lee 312-155s over 14.5gr Lil Gun (not chronoed yet but should be around 1900-2000 fps) I got a less than half inch group at 25 so it should translate to 2 MOA or better once I roll up more of this load. Only one group so far like this but I think that's because my barrel just started showing signs of breaking in my last time out (was watching each group shrink more and more once I passed about 90 rnds). Will update once I can get at least 40 (8 five shot groups should be enough to show a trend I figure) of these loads on paper with pics ofc.

[dverna]

In the shooting world, things aren't that linear. Ya'll really should be testing at 100 yds. 25, 50, 75 yd groups mean absolutely nothing.

Ain't that the truth!!!

And one five shot group is not enough. I will not even comment on three shot groups - likely to get me banned.

[Rushthezeppelin]

Never said it was anything but anecdotal at this point. Just thought I would post some preliminary possibly good results. Need to get around to loading up my latest batch of bullets (which I tried pressure casting with this time) so I can get them downrange. Will definitely be testing at 100 yds next time around, if I had more of that load I would have done some 100 yd testing. I might even man up and try doing 7 or even 10 shot groups next time. And I count flyers for the record, I'm not a sugarcoater.

[Rushthezeppelin]

Fliers are part of the group unless you called it. I have no problem with 50 shots, just the learning curve. Real accuracy, 100 or 200 if you got it.

When using an inherently accurate load I can usually call 90% of my fliers but I'll still count then towards (or rather against) my precision. If I'm simply seeing what the gun is capable of I'll discount called fliers.

Thought I posted this the other day but I thought I'd give an update. Ended up getting to shoot about 50 of my Lee 312-155s (out of 300 blackout over 14.5gr Lil Gun) the other day at 100yds. Accuracy wasn't were I wanted it to be, was getting about 5"-6" groups. Turns out when I got home and looked at the barrel it was streaked like a sewer pipe, lead from leade to muzzle. I'm pretty sure what happened is I had some of my APP Pink in the mix that had some problems with PC scraping off the driving bands while sizing/seating check. I had recoated some and sorted some that I thought were good (could still see the lead through the driving bands but obvious sheen from PC being there) but I was obviously wrong (had put about 50 of the PBTP Green through the barrel previously and had a pristine barrel so I know they are fine). Need some more testing with this mold (and application of APP Pink).

Also will have a new mold to test soon that just got in today: NOE 309 129gr PT, two cavities are PB and two are GC.

There is no point posting about 5-6" groups on a thread intended to highlight sub 2 MOA performance. Put these kinds of posts in the 100+ page coating threads that have become filled with similar useless information. Those threads are stickies (for some unfathomable reason) - but easy to find - right at the top of the sub-forum.

Thank you for your cooperation.
