R1 Hunter slinging brass

[Trapper6L]

I have a Remington R1 Hunter 10mm and it slings brass 50 ft. No, that's a measured 50 feet, not an exaggeration. I'm thinking maybe not near enough recoil spring. I haven't had any other issues with the gun but the having to go on a hike to gather up the brass. It sometimes throws a few close and then slings the next ones into the next county. Considering that I couldn't find about 4 pieces of brass on clean gravel, maybe some of it is in orbit. No signs of excessive pressure and it will do it with factory {PPU 170gr} as well as handloads. The factory spring is supposed to be 24lbs but I doubt it makes that but then I have no way to test the spring.   Any ideas are welcome.

I used a small "C" clamp with heavy cardstock as pads for the rear of the slide where I used a digital fish scale to pull and take readings at the moment the slide moves (this indicates the amount of resistance holding in battery) and then just as the slide locks open.  That will be the true spring weight at the point where the slide makes locks open.  Good luck!

Another method is to use an eyebolt long enough to capture the spring with a washer and nut through a hole in piece of plate held in a vice.

You can pull the eyebolt with the digital scale to compress the spring and take a measurement but it will only be a rough estimate for actual weight since you don't know where to stop...

If it is the same flat spring used in the Para Hunter, it is definitely not 24lb.  When i had a Para hunter i swapped in a long spring cap and a 22b spring for a standard 5" gun, and it made a big difference.

I remembered a guy that did all of the work on the custom 1911's my cousin owns and went by his shop this evening. He recut the ejector, said it was way too long and not properly shaped. He said to buy a 23-24lb spring for it, that the one in the gun is an 18.5 and not near enough. He recommended a Wilson Combat Chrome Silicone flat spring and gave me the part number. Wilson wants 20 bucks for it which doesn't seem bad as long as it fixes the issue. Now I get to wait a week for it to get here.
