Emotional roller coaster: 6 powder droppers in < 3 years!

B
I have a AT v2 and a Sartorius Practum scale. I throw 41.52 grains +- .02 grains of IMR 4064 and 76.26 grains +- .02 grains of H1000. Throw time is between 10 and 15 seconds. I get 12 to 15 throws per over-trickle. I don't like changing the charge but I can do it pretty fast. I have the original cheesy powder hopper, no reason to change. I think that it is easy to dump powder. I use the BLE app on my phone. The trickler is extremely sensitive to the tube angle but once you get it set right it is pretty reliable - powder clumps are the primary cause of overthrows. I was thinking about getting a v4 but after reading this thread about the shims and dumping powder, I think I will just shut and be happy.

22GT load data

Sorry for the lengthy post- I am starting to have pressure issues and it's only getting worse with each range visit.

My Zeus action has 22" Bartlein .218 7.5 twist M24 barrel is chambered with a .169 Alpha 22GT reamer. I use a Silencerco Harvestor 30 cal can. I am running 95SMK over H4350 in Alpha brass and CCI450. Every 150 to 200 rounds I thoroughly clean the barrel and then I bore scope to make sure to remove all the carbon ring. The barrel has 950 rounds on it.

Initially my 10 round per charge weight ladder test the barrel loved 36.7gr. I loaded 75 rounds (with a clean barrel) come to an end on round #9 with real heavy bolt lift and crazy ejector swipes. I then dropped down to the 35.8 load because it had the next best 10 shot groups, 3030fps and SD's in the 5 range. I thought that I have the recipe and proceeded to load 100 rounds and had a care free practice session.

My last match, I ran on a freshly cleaned barrel at 35.8gr, I had a dozen or so heavy bolt lifts and blew 2 primers out.

My next scheme to avoid further trouble was to find something in the 34 to 35gr region. Then my barrel loved 35.1gr H4350 at 20thou off the lands at 2940fps avg.

Loaded 50 rounds at 35.1 for Chrono and group test. On a fresh clean barrel I fired 5 at 35.8 to foul the bore with no pressure signs. But in the first 5 rounds of 35.1gr I then had blown 2 primers...so then my brain exploded and I packed up and went home for Bourbon therapy.

After an exhausting amount of 22 GT load development bumps and bruises I am out of ideas. What is happening? Are the 6GT shooters having these severe issues with carbon rings?

Best barrel I've ever owned. I shoot almost exclusively 90 gr SMK and have had success with them out to 1400 yards.
Last year I shot a 0.33" group in a 200 yard bench rest shoot. My second best group would have also won 1st that day.
BTW, my twist is 1:7. I ordered a second one on January 3rd....still haven't received it from Northland SS. Can't imagine it will shoot as well as the first. But will see.

I’ve actually got two of those barrels, ones headed back to criterion for a little checkup and just screwed on the second one to break it in.

New Contest Starting Now! This Target Haunts Me

C
When I was in college my brother and I stored our rifles at my grandparents. we got a chance to go antelope hunting so we went and grabbed a couple of our rifles and went hunting. we had verified zero with them a few weeks prior. I found a really nice antelope buck and snuck in on him and got a shot at about 75 yards. I took the shot and missed under him. My brother told me I missed low and had to have flinched. I told him I didn't flinch there is something wrong with my rifle. He grabbed my rifle while telling me there is nothing wrong with it and proceeded to take a shot at the antelope now 150 yards away and he proceeded to blow his front leg off at the elbow. I told my brother i new i didn't flinch the gun is way off. It turned out my cousin and her husband had been at my grandparents and he thought it would be funny and fucked with all of our scopes. My hunting rifle was cranked way low and my brothers was way left. That antelope got away on 3 legs and I am still pissed that my cousins ashole husband thought that shit was funny.

This has to stop

I don't give a shit what color your skin is, where your genitals are, where you want them to be, where they are on those you like to boink, who you do or don't worship, or what you like to eat. Treat me good and I'll treat you better. I avoid ghetto fucks, trailer park fucks, and leftist morons and it's 100% because of their demonstrated behavior.
