I ordered a jug of IMR4146 and IMR4451 today, why? everything was going wrong

I am out in the dusty sage brush.
The 50.7 gr 4166 6.5-06 120 gr NBT moly 3.34" 64 kpsi 3200 fps is now more Copper resistant in the Shilen select match 8" ratchet #3 barrel.
I found my limit, 10" group at 600 yards.
I will hunt closer than that on Saturday when the season opens.
 
that just doesn't make any sense though. clark, you are far more experienced than any of the posters in this thread, I heard someone mention the grit coated bullet system and that's the first thing that came to my mind as well(but I agrre, the quality of that barrel should not ever need something like this). I have a Taurus snub with some rough marks in the first inch of barrel, leads quickly but accuracy doesn't suffer, doe not foul with copper in a short span. I have a badly pitted mosin chamber with heavy tool marks, and even running .002 oversized cooper bullets, I don't get the fouling you are describing. what's the cause? have you ever had a similar experience with another rifle in your past?
 
Oi, am I happy with that powder.

629 yard kill. A new record for me. I

50.7 gr IMR-4166
3236 fps 65 kpsi Quickload estimate
3197 fps chronograph measurement

I was sighting in the scope turrets for 100 to 600 yards for 2 weeks
I was cleaning:
1) my 6.5-06 8" twist Shilen select match ratchet 120 gr NBT moly 3200 fps with 4166 powder
2) my 300WinMag 10" twist Krieger 125 gr NBT moly 3400 fps with 4166 powder
3) my brother's stock Rem700 7mmRemMag [with original barrel Rem bought from Hart the 1960s [sewer pipe]] 140 gr NBT non moly with old [I presume pre temp compensation] H4350

The cleaning process was:
rifle vise mounted on tailgate of my vehicle
Carbon fouling solvent on patch on jag
Clean patch
KG12 Copper solvent on patch
clean patch
Inspect bore for Copper at muzzle
brush 15 times with Witch's Brew [like Kroil mixed with Flitz]
Patches with Alcohol
clean patch
Inspect bore for Copper at muzzle

I had been taking my rifles to the range for a month before I got the 4166 power and using H4350 and heavier bullets.

My seat of the pants impression is that the anti Copper coating in 4166 makes the rifle shoot 4X as many rounds for the same Copper fouling.

No controlled tests were done. So anything in my head is a half truth.

.. then hunted 4 days to fill my 3 deer tags. I helped two guys get their antelopes, a raccoon, a game bird, and a skunk. To hunt on his ranch, I had to work separating cows from calves. One big mean cow wanted to kill me. I will never forget her or her yellow ear tag with black letters, "84".
I complained to the rancher. He said he hates her too because she has the snort and so does her miserable calf. To me that sounded like having the schwartz in Spaceballs. Separated cows and calves moo all night. Ask me how I know.
 
My shpeal:
1) Slow rifle powder
a) IMR-4451 has temp coating and anti Copper coating
b) H4350 has temp coating.
They are both the same speed, use interchangeably for Quickload predictions to match the chronograph.

2) Fast rifle powder
a) IMR-4166 has temp coating and anti Copper coating
b) IMR-4895 has nothing
They are both the same speed, use interchangeably for Quickload predictions to match the chronograph.

3) Faster rifle powder
H4895 has temp coating
 
I shot 3 deer with 4166 last week.
One at 629 yards.
The wife is feeding venison to all my descendants tomorrow.
I have a position in AMZN.
Things are good.

Negatives?
