I also downloaded the load data from accurate powder.

This book

My bad fellas. Still getting use to the forum.

So my 178 amax shot very well with 44 grains of varget. I'm now considering a new load to see how it does. I'm thinking a 168 grain amax with 44 grains of accur 2520 powder. Should yield around 2690 to 2700 fps. Anybody have any experience with that powder or combo?

It does not get any better than the reloaders bench in Mt. Juliet Tn. Those guys are the best.

Everytime I try to log on it has my email and password saved. I click on sign in and it tells me my password is wrong. I have to click forgot my password and change my password so etimes 4 or 5 times a day. I'm sure it's something that I'm missing somewhere. Thanks.

Absolutely. Thanks so much.

That is straight from the powder web site.

I thought something similar to that as well. Took it to the gunsmith and reload shop this morning. They said absolutely normal to have some slivers like that. I've only Put 100 rounds thru it and he told me to continue to clean and lube and clean and lube. No pressure issues going on and seat and crimp looked fine on my hand load. I guess I just got a little paranoid. I still don't really understand the reason the fusion shot like crap out of my AR10. Thanks everybody for the replies and suggestions.

I did run a patch after 20 rounds. I also used a little oil as I didn't want it to run dry. As I mentioned earlier, my hand loads shot great without any problem. I had bought a couple boxes of fusion to hunt deer with and never used them. I took them to the range to see how they shot. The fusions are shorter in oal than my hand loads. On my fusion rounds I did not load a full mag. I loaded 10 each time. The gas block doesn't show any signs of slivers but the bolt had some around the extractor. Most were located at the beginning of the bore. The cleaners I am using are pictured below.

Totally different today with the fusions.

Diamond Back db10 308. 16 inch heavy barrel with a 1/10 twist. Bought brand new in the box. Put 60 rounds in it yesterday and never had a problem. Cleaned and lubed and reassembled correctly last night for more range time today. Everything lubed that should be lubed. Had 0 shavings yesterday, but I only shot my hand loads yesterday. Thank so much. This was 100 yards yesterday. After the first 2 we're low I got it pretty close.

I see you have a ranger patch. I would like to thank everyone on the forum who served or that are serving in the military. Hats off to you guys and gals. I never served but have the up most respect to the ones that have and do serve. My son just got out of the Navy and we are glad to have him home.

Look on the right side and their are several pieces on that one side. Sorry bout the quality of pic.

Could be. Tried to take a pic of the bore. Look closely and you can see the brass/copper shavings.

Thanks a bunch, I appreciate it.

Correct. My Amax bullet shot clean and like a champ.

Here is the load chart out of my modern reloading 2nd edition. Under 180 grain bullet it states on the 4th one down that 45 is a maximum load. Now I'm shooting 178 but the book doesn't have a load for 178 so I went with the heavier grain bullet chart.

It looks like little slivers to me. Its in the neck of the bore where the bolt pushes the round into the bore. Just seems weird that yesterday I didn't have any of this with my hand loads, and today when I shot the fusion rounds I ended up with junk in my bore.

These little grooves are what I believe is leaving the splinters of brass. I'm wondering if it's not a magazine issue? My never fired lapua brass does not have them near as bad as These federal fusion brass.

Thanks for all the replies. In my book that I'm using it says 41 to 45 grains. In my research I found that 44 grains was a good load to shoot. If I need to go down in powder I can. Will try and post a pic of the case.

Just getting started reloading. Love shooting and any kind of hunting. Brandon is my first name and I live about 30 minutes from downtown Nashville in Old Hickory. Some of you will probably get tired of me asking so many questions lol lol. Hope everybody is doing great and I look forward to learning as much as I can.

Brand new to the forum. Thanks for any help that may be given. I have a diamond back AR10, 16 inch heavy barrel, with a 1/10 twist. I loaded 178 grain amax bullets on never fired lapua brass, with 44 grains of varget powder. My hand loads shot fine, however I shot 20 rounds of federal fusion and that's where the fun began. It would not pattern at 100 yards with the federal shells. It left copper slivers on my bolt and the mouth of the bore. My gun was also leaving 2 little grooves just below the collar of the shell. Any one have any idea on what may be going wrong? Thanks again for any help as I'm brand new to the AR10 world and the world of hand loading.
