Loads for N135?

[acloco]

Anybody using N135?

[jo191145]

Yep. Anything I can help you with?

Have any starting loads for 35/40 gr Bergers and 40 gr VMax?

[jo191145]

I've been doing most of my testing with 40 Bergs so I'll start there. I would suggest starting at 25.5gns and plan on stopping around 27.5. Warning Keep a close eye on pressure indicators. I have gone higher than 27.5 but with less than stellar results not to mention popping a primer or two.
You should find your best results between 26.8 - 27.4. At these load levels you should be well within safe pressures.
Velocity should be around 3730- 3800. Trying to push past 4000 will get you in trouble. Just had to try

Keep an eye on your neck expansion. It seems to me Viht powders are not reliably expanding four seperate lots of brass.
I'm gonna try Benchmark and 40's today just to measure my necks. Trying to figure out whats up.
Annealing might be in order.

jo191145 - Thanks for the info.

Does Viht have any load information online? I have not been able to locate any.

[jo191145]

No Viht does not offer any load data for the 204. Thats one of the things that initially drew me to it. As close to wildcatting as one can get with a factory cartridge
Walt Berger has offered up some quickload data for Viht powders. In my experience it is extremely conservative.
You can search this forum for it and other posts by me and others concerning Viht powders. Theres been some discussion this summer concerning it. I initially posted some results from last winter using 35 Bergs and WS2 in my old tube.
Have you decided to go with a bullet lube yet? You might want to try Viht with naked pills first. It seems to help prohibit coppering. At least it did in my barrel. Bergers also give me less copper. V-Max the most and Nosler/Sierra not to bad. This new tube now coppers less than my previous three. When it was new it was horrible. Trying to break it in I got to three shots and no longer could clean it. The copper was like shards and tore the patches to shreds.
In a fit of anger I lapped it with 600 grit paste. I'm not recommending this procedure to anyone!!! I was ready to bend it over a rock. I think they switched direction during the bore reaming process.

If I was not computer illiterate I would offer up some Viht post links. Good Luck and mic up them necks. I'm totally confused on that issue.

Good Luck and mic up them necks. I'm totally confused on that issue.

jo191145 - YES on the WS2, waiting for it to arrive from another member. Cannot seem to find anyplace to purchase...in quantities of less than a couple POUNDS! ugh!

Mic up them necks...what do you mean? My Savage does not have a tight chamber..so I am ok.

Interesting on your findings of what coppers up barrels faster or not. Of note, my Savage 12FV in 223 can go 4-500 rounds before CLEANING...let alone worry about copper. See my other post of "manning the fenceline" - that rifle had just under 400 rounds down the tube prior to that trip and he put another 150 down the tube in a couple outings in Montana.

I checked accuracy prior to leaving for Montana with my standard H4895, CCI450, & 69 gr HPBT's at 3000 fps...and it shot 1 1/4" group at 300 yards...so I deemed it ready to make the trip.

I have let Hoppe's copper remover in the barrel overnight, because I did not believe this barrel did not have copper in it...but only got a hint of the "deadly green" on the patch. (work up to leaving something in a barrel overnight....could get ugly if you don't).

Too bad for Viht...more people would probably use their powder if they did.

Oddly enough Viht 133,135 and 140 do not always expand the necks on my collection of brass. Wierd. Other powders H-4895 and Benchmark do not have these problems.

WS2? I bought the 1lb "sample" from lowerfriction.com. Something like $40.00 bucks shipped anywhere in the lower 48. I've used it for all sorts of things.

You posted your desire to switch to moly because you were tired of cleaning copper. Every 500rds with Hoppes does not seem to be a problem. Mines running quite well now too. The v-max will copper near the throat so I don't use them.

500 rounds down the tube occurred in the 223 with Nosler 69 gr HPBT match bullets. My 204 is a different story.

Will try the website mentioned...
