Model 1 Sales 300 whisper upper function problems

[sharpshooter33]

Ok, I've fixed my extractor problem. I now have a fully functional 300/221 fireball from Model 1! I'm using Jrippers load of AA1680 at 11.0gr and 220gr SMK's sized alittle longer than Corbon's, but they still fall below 2.260 OCL. I've used RP and LC cases and both are just fine. This load seems to be shooting somewhere around 950fps.

I'm a happy camper! Now I just have to get a suppressor and my project will be complete.

BTW when I put it back together I ordered a MRFS-C and drilled a hole for my AGT. It is a bad ass looking setup right now. Will be even nicer when I get it suppressed.

I see a 300/221 bolt gun in the future also. I'd like a real quiet one. 8-)

Thanks for all the input here guys. I would never known I had a problem unless I was reading these posts and I wouldn't have known how to fix it either.

Thanks

Glad to here your upper is running well. Mine is also, altough a few weeks ago, a friend came over, and we went to try it out, and I got failure to feed/extract short stroking again, sub sonic or super sonic. When I pulled ou t my bolt, I found that the carrier key had come loose. I then noticed that the "staking" on the model 1 bolt did not even touch the allen screws. I put red loc tite on them, and staked them a little deeper, and it all works again.

Just something to check if you are using a model 1.

Thanks everyone here for their help, as I don't think I could have gotten it going without the input here

I finally chronographed my 11.0 AA 1680 and 220 sierra load. Out of my 16" M1S ar, 3 shots averages 980, with a high of 1020 and a low of 933.

Only did three, as that was all I had on hand, and it was starting to rain.
