Magtech at the Range

Mail order from Miwall back in early Feb.   Price was good and figured if it worked out availability should be OK. Reality has been as you know quite different than my prediction...

Don, Thanks.  A little followup on the results above.

A couple weeks later shot the Magtech through my Underwood with the adjustable sight.  My hope was that the Magtech would hit center of target with the sight elevation set to 100 yds. 

My buddy was able to get his shots pretty close to center at 100 yards on a US Army 'A' target with 12" bullseye.  But he told me he was covering the entire bull with the front sight. 

So I *think* the magtech shoots higher than the PSD 86, and it may be simply that this Underwood's front sight is a little too tall.  Next experiment will be to try 6 oclock hold with the elevation at 200.   I probably should have done it that day but for me it was a casual day at the range.  He wanted to scope in his hunting rifle and I brought the carbines for him to shoot as his dad had qualified on carbine in WW2.  Then we shot revolvers just because the 25 yrd lanes were open.     

I saw 1 box of Magtech at a LGS last week for $37 bucks. I was going to get it just to try it even at that price but someone else beat me to it. 

I'm going to keep my eye out for it at this LGS. Price sucks but it's the 1st .30 Carbine ammo I've seen all year

 

A measurement of sized cases will tell if it’s short, which renders long head space.

I didn't notice the one from last Tuesday until I went back and looked through what I picked up.

Interesting that not one was partially out like pictured in the CMP thread.

Hard to know if this is a 'soft brass' situation as argued in the CMP thread, and/or the result of short cases. Maybe also the primer cup to case interference isn't as tight.  When the brass hit the ground, maybe the cup came out then?  

I'll say many of the rounds ejected forward (1 to 2 o'clock) which is nice IMO.

Using a vernier caliper:

Case length for all three Magtechs that lost their primers is 1.280"

Diameter at the base is .357 to .358"

Of seven random cases that kept their primers, legths measured 1.278 to 1.287" with three at 1.280"

base diameter of same ranged from .355 to .357, mostly the former.

The LC 67 I picked up (not mine) was 1.278" long and .355" base dia.

Of three random PSD 86 cases are length 1.280, 1.285, and 1.282" long and  base dia .355"

Based on the soot residue, there is no evidence gas or flame pushed past cup.  Yes there was soot on the extractor workings, but thats not been unique to the Magtech.   With the PSD there is also a ring of primer sealant on the bolt face. 

I still have some Magtech and will continue using it until its gone.  Probably won't buy more, at least for a while.  I have some LC71  to experiment with next, and qill be keeping an eye out for what else becomes available that might be suitable for matches.

Used 35 magtach yesterday, recovered 29 cases - all looked fine.

Also used 15 PSD, recovered 14, and found an LC4. 

Temperatures in the low to mid 40s.
