6 creed with 115 nosering DTACs?

[khuber84]

Be ready for that 26 to go wild on you. I bought a couple 8 pounders and felt like I had it figured out.....then out of the blue a load that showed no signs of over pressure started blowing primer pockets out of the brass.

I'm scared to take it past published velocities by more than 5% or so.

I don't run it that hard, that's just as high as I went in testing. I typically find ejector marks and back it off a grain. I run 44.5gr with 112s in my 18in barrel at 2950. I was able to get up to 3100 with 47gr before getting psi signs.

I've been there myself.....and then something changed. It happened in a 260ai and a 243.

Are you one those guys that doesn't clean your barrel? I'm not a member of that occult. I watch my velocity. If it goes up on avg by 30fps over my know info without any major temperature change, I clean the throat.

You and I are similar. It was taking me about 300 rounds to carbon up my 260ai.....the 243 only had about 200 down the tube in it's life.

Oh yeah I don't go that long between cleaning unless I'm running varget or H4350. RL series powder needs cleaned often. Stuff is dirty as hell, and suppressor just makes it worse.
