blairmckenzie1 Posted May 3, 2013 Share Posted May 3, 2013 Just got back from Multigun Nationals. Found out while I was there that there is something wrong with my ammo. My load is mixed brass, a Montana Gold 55gr FMJ and 24gr of TAC and a Wolff magnum primer. I had basically had bullets coming apart and splattering all over targets. There are some small marks on my comp (surefire). Has anyone else had this problem? Some folks at the match thought I may be over crimping and breaking the jacket. I have never been an "over-crimper" and have pulled a few of these bullet and haven't seen any evidence of over crimping. I havent been able to get through to MG with all the craziness going on. Any advice? I still have about 3000 of these bullets left over so hopefully I can make them work. Thanks for the help Blair Link to comment Share on other sites More sharing options...
PTRDRGN Posted May 3, 2013 Share Posted May 3, 2013 I've had the same issue with H335. I hope you get some good info, I haven't been able to research the isssue yet. Link to comment Share on other sites More sharing options...
gixxerjunky Posted May 3, 2013 Share Posted May 3, 2013 (edited) I have seen factory ammo strike the end of comps and messes things up. I wonder if the bullets are tilting slightly as soon as they leave the muzzle. Edited May 3, 2013 by gixxerjunky Link to comment Share on other sites More sharing options...
AlamoShooter Posted May 3, 2013 Share Posted May 3, 2013 I shoot them over 27.5 of BLC2 at about 3000 fps, they work great. even out to 400 yards , I thought the price was less than Hornady when you buy 3500 a time I only found the Hornady in 100 packs. ? I will look harder. Link to comment Share on other sites More sharing options...
gixxerjunky Posted May 3, 2013 Share Posted May 3, 2013 PV had hornady 55gr FMJ BT for $91/1000 the MG seem to be almost double that. Link to comment Share on other sites More sharing options...
old506 Posted May 3, 2013 Share Posted May 3, 2013 What is the twist rate of your rifle? When you worked up the load did you have problems? Or, did you just load them up and take them to the match? Link to comment Share on other sites More sharing options...
MarkCO Posted May 3, 2013 Share Posted May 3, 2013 How many rounds on the barrel and what barrel? Link to comment Share on other sites More sharing options...
blairmckenzie1 Posted May 3, 2013 Author Share Posted May 3, 2013 barrel is a daniels defense 1:7 twist, with probably 2500 rounds. it has shot great for a long time before the match. didnt do a ton of load work but have shot probably 500 of these rounds with no issues.

MarkCO Posted May 3, 2013 Share Posted May 3, 2013 Well can probably rule out throat or gas port erosion then. I'd pull the comp off and look at the chamber and crown. Shoot a few with no comp and see what happens and then go form there. Link to comment Share on other sites More sharing options...
ericm Posted May 3, 2013 Share Posted May 3, 2013 ...it's the bullets, probably certain lots, and Montana Gold seems to be aware of the problem. My friend was shooting them just before the Noveske COMG Championship, loaded with a mild load of TAC, I believe. They were coming apart both at the muzzle and further down range, both in his rifle and another shooter's rifle. At one point I was hit by frags coming out of the comp on the other shooters rifle. The same load, loaded by the shooter, with Hornady 55 gr FMJ, showed no problems. My friend called Montana Gold and was told they would replace them when they could get around to it (due to being extremely busy). I was there, I saw it. ; ) ericm Link to comment Share on other sites More sharing options...

ericm Posted May 3, 2013 Share Posted May 3, 2013 I'm sorry, I don't know bad lot # / shipping dates. I think my friend got a coupon at RM3G 2012 and sent it in, so around last half of 2012 when he got them. The best bet is to call Montana Gold and press them for details. ericm Link to comment Share on other sites More sharing options...

Forgetful Posted May 6, 2013 Share Posted May 6, 2013 (edited) when I get off work and have time I might expand more, basically same story. Comp strike or two, keyhole at my last match, bad accuracy with flyers that miss the target. Last weekend I shot my 75 Hornady reload and still perfect.

ClutchUSMC Posted May 6, 2013 Share Posted May 6, 2013 This explains a lot. I have been driving myself nuts trying to figure out what was causing this... Glad it only wrecked 1 major match for me... Link to comment Share on other sites More sharing options...
JimmyE Posted May 7, 2013 Share Posted May 7, 2013 A fellow shooter in my club recently had the exact same problem with MGs. He has a lot of reloading experience with no previous issues so he was pretty baffled and also trying to make adjustments to his crimp and so forth. I'll point him to this thread.

jonny4523 Posted May 9, 2013 Share Posted May 9, 2013 Sounds like the same problem I'm having ============================ I have a good buddy who had, what appears to be, a series of baffle strikes at a recent carbine match. Up to this point, rifle had about 200 rounds through it. Battlecomp was brand new. Rifle is a factory Noveske MK18, M249 barrel, 1:7 twist. Ammo are reloads: 24.5 tac, 55gr montana gold, tula SMRM primers. Here are the results: Another buddy and I were shooting the same ammo, both 16" BCM BFH rifles, both with Battlecomps. Both shot great (infact, I took 3rd overall). I verified after the match that my Battlecomp was free of strikes and it looked like new. I have shot that ammo since then on the range with a chrono, but no rifle matches. Well, I took a look tonight and this is what I found: It had to have happened during chrono. I see a ton of people using this load and I couldn't find a single other instance. I worked this load up with both my 16" BCM and my 18" Loki and 24.5 was most accurate. I was hoping that this would be my go to round for 3-gun for anything shy of 200 yards. What do you guys think? I need some help on this one. Doesn't sound like this is that common of an incurrance. Yet it seems to have happened to both us of. Common denominator: 55gr through 1:7 barrels. Link to comment Share on other sites More sharing options...
CocoBolo Posted May 10, 2013 Share Posted May 10, 2013 This makes me glad Montana Gold was out of bullets. However, I've been shooting the 52gr Nosler Spitzers over 24.5gr of TAC with no issues, but then again I have a Rolling Thunder Comp on a 20" 1/9 twist barrel. Sorry to kill your hope PV does not have Hornady .223 bullets in 55gr, just grabbed the credit card and went there to clean them out, too late.

jerseyglock Posted May 15, 2013 Share Posted May 15, 2013 FYI, MG changed their 55gr die back in October 2012. I'm still waiting for Norm to reply back on replacement. Link to comment Share on other sites More sharing options...

I've called and left voicemails. No return phone call yet. I'll try again today. Link to comment Share on other sites More sharing options...
tohm Posted May 15, 2013 Share Posted May 15, 2013 I bought two boxes of the 55 gr FMJ from MG, the markings show they were inspected 11-12-12 and the lot number appears to be 06128 42255 7, is there any indication of when the bullets with issues were produced, shipped or what lot numbers they were?

rtp Posted May 15, 2013 Share Posted May 15, 2013 Norm at MG got back to me, basically he's gonna replace the bullets as soon as they are sure the problem is fixed. This would seem to indicate no MG .223 55gr is good to go at this point, versus some individual bad batches, would it not? I've been monitoring MG lately exactly for .223 projectiles...but the above makes it sound like it's worth holding off until some confirmation or announcement is made.. ??
