I did not try 8208 even though I have 8lbs of it. I settled on 33 grains of Benchmark and that gave me in the middle 3550 fps. Good enough for prairie dogs.
How about powder for the 58 grain Vmax for the 6mmBR?

That is slow, real slow, unless you have a 20" barrel.
You will find it hard to wear out that barrel with AA2230 or H335. We shot cases of H335 years ago, Rem 7.5's, in Rem brass.

AckleymanII, can you give me a load of H335 with the 58 grain Vmax? I can't find any data for that powder. I've got pounds of VV135 and H335 but didn't try them. I did try my AA 2230 and the loads were way weaker off the chart. I think because it's made in the Czech Republic. Gave up on it.

I use 33.3 gr 8208 and 58 gr VMax. 3580 fps. Shoots under 0.350". I use 58 VMax because they are always in the store. The 60 gr Sierra Varminter with 33.3 gr 8208 is the most accurate bullet I have ever shot for a GH hunting load. Reguarly shoots about 0.250". Have shot some groups in the 1S with this bullet.
I only buy 8208 now to keep it simple. I didn't like the fps with many other popular powders. H322 was good. Might get good accuracy with Varget and RE-15 but the fps was lower than 8208.

IN a 24" barrel, accuracy node should be in the 3700 fps with H335 and 7 1/2's.
For colony varmints, cleaning frequency is 300 rounds with H335, 125 rounds with 2015 due to the difference in coatings on the powder.

Tried it again and groups are opening. Wow there is a big fireball coming out of my 24" barrel with H335

Gene Harwood, NBRSA Director, set a world record with his 6 BR shooting 60g Bullets at 3700 out of a 24" Max Heavy Varmint barrel using H335. Lt32 and H322 was available to him at the time.
I have shot 335 in a dozen different barrels(minimum)11-14T with short to .058 freebore since Gene Has Passed. Accuracy has always been nothing short of amazing with incredible speed. What is the icing on the cake is how clean it burns at the accuracy node which will be hot. Barrel life with 335 and 2230 will be 8000 rounds if you start off with zero freebore, you will be lucky to 1/3 of that with more popular powders.
In 20" barrels, I shoot the 60g Sierra at 3550 into groups so small it is hard to believe.
Webster, if your barrel did not like 2230 or H335, you were probably not shooting hot enough loads, as I have yet to see a barrel not shoot, very tiny groups with these two powders. Of course, I have not shot the 58g V max, but have shot a lot of my own 55g-65g bullets along with many thousands of the 60g Sierra. Barrels do have a mind of their own.
H335 and aa2230 will not shoot the 55-65g bullets into bug holes until you get to some pressure, and your reward will be some fabulous throat life...you will just have to see it to believe it. H335 worked very well with 70g Sierra Blitz kings, but trajectory sucked hind tit compared to the 55g Nosler. Groups with the 55g Nosler were spectacular at 300 at 3900fps...check out the BC of the 55g Nosler!
The 60g Sierra is one heck of a coyote round, including quartering shots with good bone breaking ability + penetration.
I punched out a couple of retired 23" 6ppc barrels to 6 BRX and 6 Dasher. AA2230 powder in both barrels with 55g Noslers shot bug holes at 3850fps, Rem 7 1/2, and got 4100 in a new 27" Brux 12T barrel with zero freebore, brx.
If you can find any of the old 6mm, 60-62g benchrest bullets, they make excellent p. dog, ground squirrel, rock chuck, and coyote bullets.
The quirk with AA2230 and H335 for me has been the faster I have shot it, the more accurate it was up to the point to where I was getting bolt click, 6 BR, 6 Dasher, 6 BRX.
Back during the p. dog wars, we shot 300 rounds in between cleanings with Hart barrels, 12-14T barrels, zero throats, shooting 60g Bullets with H335. We each had a 5 gallon bucket for each rifle we carried, including 6 BR's loaded for the two week trip with barrel life of approximately 8000 rounds. We shot the barrels till we could not see out of the scopes due to barrel heat. Hall M's and Panda's in fiberglass stocks, we filled the barrel channel full of water out of a squirt bottle when the barrel got hot. We cooled the barrels with water down the bore after we had a second barrel too hot to see through the scope...it was time for a break, anyway.
At that time, Lt32 was $50 per 8 lb keg. AA2015 was also darn good powder. Both of these powders would foul a barrel in 125 rounds, especially in 223's and 22 ppc. The coatings on these powders create a powder ring in the bore for sustained firing on colony varmints, H335 cured that problem in spades and AA2230 is just as good.

DanS, I think that your load is too light, remember the pay off in barrel life.
With the lot that I have, I shoot 32.5 - 33.5g with 60g Sierra's, work up to that load with 7 1/2's.
Also shoot 29.5-30.5g in various 6 ppc's, with the 60g.

Yes. Go with the N-135. I shoot it with all the light bullets from 58 V-Max, 70 Nos BT, 87 V-Max with great accuracy and speed. You will love it. I have praried dog kills at 914, 960, and 975 with the N-135 and 70 Nos BT's in a 6 BR and 6 Dasher.

I shot for two days on dog towns shooting LT32 in my 223A and never cleaned the barrel. About 400 rounds. My longest kills were on the last day at the end.
I do use Tubb Dust in my powder.
I will take pics of the bore when I clean it.
