VV N135 Temp Stable?

[WYO300RUM]

Good idea, I'll run down to the Cody, WY Scheels and pic up a pound and try it

I was in Billings last week. Stopped at Scheels. They had 8 pd. N570 only. Dont remember price.1 pd. N565, N560 and N550. If I recall correctly they were $51.99. I have plenty 570 and 565. Haven't seen 560 in long time. I got 3 pds. LRT for $42.99 pd.. Was sale on H1000. $56.99 pd.

I believe that N135 was actually designed around the M80 308 round (147gn). Probably for the FAL. I use it in 223 with 53/52 gn bullets an its not as dense as N140/Varget/8208XBR. I have been trying it with 168's in 308 but haven't decided if it's a fit or not. I would probably go with N140 for the 168's and 175's.

I cannot address 135 directly, but I can tell you for certain 120 is ABSOLUTELY temp sensitive. Loaded some 20 VarTarg loads, one with H4198, the other Viht 120 in mild temps. Took some out this summer and the 120 ended up with a heavy bolt lift and the Hogden was just fine.

On my 1 kg bottle of N-135 it states it is temp stable. I've used alot of N-135 but just in the summer so I can't attest to the stability of the powder.
I see it also says temp-stable on my bottles of N-133 and N-140.

Varget = VV N140. Check a Powder Rate burn Chart. At the cost of powder and primers. i would humbly say that VVN135 is a waste if you are looking at 308 and 175-grain bullets. N150 would be the best choice for 190-grain bullets.

I used to shoot NRA "across-the-course" matches with 308 and found 4x
.30 cal ammunition cases with 125 Speers over 44.0grains of N140 for rapid-fire to reduce muzzle jump. I just pulled a half- dozen to see if they will work - with 175's; normal load would be 43.5-grains for a bolt -gun.

N135 is a bit fast for 175s. N135 does work well for 135s. Been using N140 for 155s and 168s. N150 for 175s and 180s. Seems to do well. H4350 also works well for 175s and 180s and up. Your milage may vary.

Thanks to all. We shoot 155s not 175s, so N135 might be perfect for our application.
