i hope this works..lol...first time for everything i guess

Glad it's working and good shooting!
I'm gonna say it was the extractor needed defanging.
wisdom of the crowd - ocharry - 03-08-2023
BFT...i do in fact believe the extractor was absolutly involved in what it was doing...even if it was just a little...first round out of it told me the extractor had changed the ejection timing...because that is the only thing that changed
i do know that before the cases were hitting the case deflector pretty hard because it always left a lot of brass smudge on it...i always cleaned it off so when i made changes it was kind of a marker
but this last run of testing it didnt show any signs of brass on the deflector...nothing...and i think that is because the extractor is letting go of the rim just a touch sooner and the heavier buffer slowed the bolt down.....
just watching it run now vs before, it is a completely different acting rifle....we shall see... if it gets colder i want to run some rounds through it then for another test run....
i want to say it is fixed....but.... it is gona have to prove it to me..lol...lots more rounds down the pipe....bigger sample size if you will

well boys yesterday was the first day it was cold (28-30) and not doing something wet....so i took the grendel out for a spin ....
first round out it puked....what the heck is goin on here...cleared the rifle and next round puked...this test was with the 95gr v-max bullets...deliberate..yes...so for sure the cold has been and is still a problem....
after the gun warmed up it did seem to get better....but a couple times the bolt was locked open and the case was stuck in the extractor...i had to literally pull the case off the extractor....so i think i still have a problem with the extractor...although it does not seem to hold onto the rim of the case when i have it off the bolt...so not sure what is going on with that thing but before i take it out of the rifle again i am going to lock the bolt open and see if i can make a case stick on the bolt to see just where it was or is getting caught
it is running better than before when it was cold...but we aint there yet....heck it may never run these 95gr bullets consistent...well when it is cold anyway...ran them fine the other day when it was in the 50's
i'll be back...lol

Can we get some pics of your extractor?
Preferably the underside of it so we can see the lip corner geometry from a rear view angle.
wisdom of the crowd - ocharry - 03-16-2023
LRRPF52...
the back side of the lip was exactly where the case was being held onto...it was not doing it with the extractor off the bolt..but when installed on the bolt those corners were digging into the rim and trapping the case from ejecting....when i took the bolt out of the rifle and played with it under the big eye i could see exactly why this was happening...and i could make it happen....for sure the extractor was holding onto the rim
so i defanged the back side of the lips until they did not hold onto the rim...put it on the bolt, take it off...probably had it on and off the bolt 6-7 times....when i got it where i thought was good i polished it really well with a felt bob and some jewlers rouge
i also relieved the out board side of the radius just a touch....not sure if it needed that but i cleared it anyway...looked like the case was bumping there to and helping with the locking the case on the extractor thing...lol...not now....case comes off the extractor when it is on the bolt like greased lightening...lol.....oh sure ...lol
rainy and snowy today...but saturday it is supposed to be in the 20's....more testing if you please...making some more testing fodder today so i gots me plenty of boolets for saturday
so if this dont work out...fingers crossed...when i take the bolt out i will get a couple of pics for you to look at....i do plan on getting a couple more extractors from BFT just to have extras...i did order a bolt and a extractor kit from him the other day
also want to add BFT....i tried to answer you PM but it said your mailbox is full and i cant reply until you empty it some.....something about exceeding your limit
thanks guys

OK fellers...back with the freezer report..lol
yes it was a freezer yesterday...saturday 3-18-23..high was 23* with a wind of 10-15mph...wind chill was 9*
took the gun and ammo out to the table and set it up and left it there for about 20 min.....the gun and ammo was already kinda chilled because i left it in the shop...was about 45* i guess in there...i dont keep it heated unless i am in there doing something...was 16* friday night
i loaded 20 rounds with the 95gr hornady bullet and h322 that it likes...just didnt want to run consistant before when cold..but does pretty good in the grouping department
so after the soak in the freezer for about 20min, i went out and just banged at steel with 10 rounds....my fingers were popcycles after 10 shots....but the rifle ran perfect ...shucked them cases out like a boss...well now that is an improvement....so i left it siting out there in the wind and cold and came into the house and put some wood on the fire...build a pot of venison stew and made a cup of coffee and pondered what just happened...45min all together i guess... rifle is still out there in the freezer for all this...i wanted it really cold for the last 10 rounds
so last ten rounds went just like the first...not even...notta..nuttin...ran flawless....so... did we fix it??? more testing and time i think...i really want to trust it but a 20 round sample size is kinda small...well it is 23 rounds i guess, i did run 3 rounds through it the other day after i worked the extractor...it was about 45* that day but it shucked them out too
i will say i was impressed at how hard those 95gr hornady v-max bullets were smacking the steel at 200...pretty good whack..and a pretty good splash group there too...
so right now i am pretty happy... we have made a very big improvement... and for the second time i want to say i think we fixed it...it sure looks like we did...but i dont really want to go there just yet.....but it is running better than ever...plus i bet if you could get a 5 gal bucket sitting in the right place it would put all the cases in the bucket ..at about 4 oclock .....i had a nice little pile of 20 about 4-5 ft out...so that looks good too
so i want to get some more stuff loaded and shoot it somemore....test more and maybe get some blood on it...thats why i built it to start with
so right now i am happy with this rifle i built...very accurate..looks good and right now i want to say the gremlins are out of it...we shall see i guess and i want to thank you all for chiming in and helping me trouble shoot this thing...im not sure i would have looked to hard at that extractor if not for you guys...glad you pointed me there for sure
thank you all very much

So far, so good, but as you say time will tell!
