I don’t disagree with what you wrote.

In this instance, it’s in an AR. It currently has a 308 caliber flat coil spring and 12 ounce buffer and I’m not sure what the bolt weight is, but it’s heavy.

And still slinging brass out about 12 feet away.

So, it certainly does need more resistance than what it currently has.

When using a non-scientific fish scale to see how many pounds the pull is on the charging handle, it’s around 18 or 19 pounds when fully rearward.

Which is still not enough.

So, that’s the reason why I’m in the process of making a 2 stage buffer for it, with heavier springs. Similar to the Armaspec stealth. But not quite.

In a different upper, I heavily modified an armaspec buffer to work in it. Only in this case, I am using an A2 rifle length to further slow the ejection down with the longer action.

I had to make a different/longer buffer on my lathe due to how the guide rod and bolt works, but I’m just trying to find the heaviest springs I can find. If it’s too heavy, I can always reduce the spring weight some. Or skeletonize the buffer weight to reduce some of the mass of it.

That’s why I asked about the spring sizes earlier so I could tell whether I wanted to try to use that style spring. Since I’ll be making the guide rod and buffer setup myself, I can make it any size that I want. I just needed some numbers to get an idea as to whether I wanted to use that kind of spring based on the diameter and length of it.

Didn’t know a guy could get a 24 lb spring.

I’ll look that up.

In the process of trying to design a better AR buffer for the carbine.

Thanks !!!

Edit:

Any way you could give me the inside and outside diameter and length of the spring? If it isn’t too much trouble?

Yeah, those would work.

The xtreme bullets are total jacket though. And about $20 cheaper/500. But, those bullets are still better priced than the Hornady. Thank you.

Thanks Ken.

Sqlbullet, velocity is what I’m going for. If I can squeeze extra fps out of my loads, that’s what I’m going for is Ft Lb of energy on target. I am not looking at my notes but I think when I shot these over a chrono, they were hovering around 1570 fps ballpark?

The distances that I normally hunt at are pretty close. 70 yard shots are rare and would be a very long shot due to the terrain and all the growth. Typically 18-40 yards is pretty average so I don’t exactly have to have cloverleaf groups as long as I can get the bullet into the boiler room. Plus, being a carbine, is going to lend itself to being more accurate for me than it would a handgun shooting at the same distances.

I got the new optic zeroed yesterday. Finished off the armscor 180 grain pills I had stashed back. Not finding any more available at any of my usual haunts. Natchez. Powder Valley. Etc. Out of stock everywhere. I know they’re imported. Phillipinnes I think, but they aren’t anywhere to be found now.

I may end up getting some of the xtreme munitions 180’s to use next. They’re $60/500

Best alternative I can find for that is $20/100 at midway for hornady pills.

Anyway, The gun zeroed well. I like the little prism optic on it. It’s a circle dot reticle similar to the Eotech and other than the center dot being a bit big and covering the entire little bullseye dot, will work well for deer hunting for sure. I didn’t need to use the illumination. Just used it as a simple scope yesterday.

I think I’m going to try some of the Lee cast 175 powder coat and start at maybe 13.8 or 14 gr and work my way up to get a comparable load so I can write it down in my book for perhaps some future time when getting components is harder and I may have to fall back on casting my own stuff full time.

I’m using 14.5 gr of #9 with the jacketed so I would prefer to err on the side of caution instead of going right for the horns at my max load. I’m not sure what the hardness is of the lead I’m using.

Do any of you think I should start even lower and go up or does 14 gr seem like a reasonable starting point and fire for effect? Even 14 gr is a little spicy. But the gun is doing fine with 14.5 and jacketed.
