Windham Weaponry 7.62x39 Review
« on: August 05, 2018, 11:08:15 AM »
Well, here it is! The long-awaited, much-anticipated review of the “Windham Weaponry 7.62×39 SRC” Model: R16M4FTT-762 review. There is no need to hold your breath any longer!

Of course, I am kidding. I doubt rather the review was long-awaited or much anticipated, let alone known about.

Anyway, this will be my last review for a while.  Work that actually pays is demanding more of my time and attention. So, there is going to be a long dry spell of reading reviews from me.

I hope that you enjoy the read: http://guntoters.com/blog/2018/08/05/windham-weaponry-7-62x39-src/
The fact that the GOVERNMENT would even consider removing the natural right to bear arms is the very reason why the 2nd Amendment was written.

An update to the "MSR47" project is available. I have good news, and I have bad news.

Another very good report.
I have been told that the direct impingement guns need to be run 'wet' as opposed to dry/or dryer than the piston guns.
Interested to find out if increased lubrication improved the function of the rifle.

I updated the review with today's findings.

It seems that it may have been a ammunition issue.

And yes, I made sure that the bolt was lubricated very well, but I do believe that the ammunition used in the latest effort, solved the problem.

If you don't want to read the article to read the update, here is the update:

"If you have read this article you know that the 'MSR47' has had some feeding issues.

Today, the third day of evaluating the Windham Weaponry 7.62x39 SRC resulted in high-praise for the firearm. It seems that the ammunition being fired was the issue with multiple FTFs.

For this range session, I stoked two 10-round magazines and one 30-round magazine with Golden Bear 123-grain HP ammunition.

The Golden Bear 7.62x39mm, 123-grain HP ammunition clocks out at 2404fps, which is faster than the Fiochi 124-grain FMJ ammunition (2310fps) with which I first tested the firearm. It seems that this extra oomph provided more 'ass to the gas' that was being returned to cycle the action. There were absolutely no FTFs and the bolt locked back on the empty magazine every time. This, of course, makes sense.

Consider that the 'MSR47' uses the same buffer and buffer springs as the .556x45mm/.223 Remington version of the WW SRC.  The velocities of these rounds are almost the same (3240fps - 3260fps average). The Fiocchi was running at approximately 2330fps, which is quite a bit lower than even the lowest rated 5.56x45mm/.223 Remington ammunition. Thus, the Fiocchi would not cycle the action properly, because there simply was not enough gas pressure being returned to properly cycle the action.

The Golden Bear, even at approximately 2404fps velocity, was enough to properly cycle the action even though it is still quite a bit lower than .556x45mm/.223 Remington.

Some further experimentation might reveal a 'window' in which the MSR47 operates. For now, I would consider a minimum of 2390fps to properly cycle the action 100% - until I can prove otherwise.
This may limit the MSR47 to certain ammunition, but there is plenty of ammunition that falls above my perceived minimum.  I will try some Wolf Poly Performance (≅ 2410fps), but I prefer the brass-coated (or brass) ammunition to others.

But, this all makes some sort of sense to me. The Windham Weaponry 7.62x39 SRC was intended to fire a Russian cartridge; the hammer spring was beefed up for Berdan primers, the feed ramp was modified to accept the 7.62x39mm cartridge, and magazines that were developed for the AR to house the cartridge and allow them to feed properly function properly.

So, as of this point, I give the Windham Weaponry 7.62x39 SRC a 'ready to launch' status. And, I also give Windham Weaponry lots of credit in solving issues that were with the original Bushmaster (the original Windham Weaponry) carbine in this caliber offering to provide us shooters who really like the 7.62x39mm cartridge and excellent platform from which to shoot them."
