[OPEN GLOCKS]

The powder is Vihtavuori N350 - too bad, got to use whatever I got. I read in here (and Glock forum) that N350 can use as Open powder (of course, not as good a HS6 or Autocomp) - so I figure I start small (4.0gn) and go up the powder load.

Hopefully I won't blow up my gun (at least not yet) since right now my gun is not 100% recycle after each round.

One question that I asked was the shelf life of the powder - is 1999 too old? when does the powder goes bad (or lose its power)? I don't have much experience with Open powder, most of my Tigtgroup or WST or VVN320 are used up within 6 months after opened used for my Limited gun load.

I guess I need to read more before some other people call out for my stupidity again. LOL.

Need some help with my load:

Firearm: SJC Glock in .40 (built from G22)

Powder: N350/6.5gn

Xtreme 165 RHFP – OAL 1.135

Xtreme 180 HP – OAL 1.138

I tested and started with 4.0gn and she did not even cycle the slide – keep testing/moving up to 6.5gn and now it will recycle 90% (I think I may have to go to 7.0gn). I have not even started any chrono yet (just want the damn thing to recycle first! LOL).

So I tested today with my 6.5 gn load and found that the recoil with the 180g was much higher/harder than my 165g bullet (similar OAL/same amount of powder).

What is the reason for that? I thought heavier bullet will give smaller flip?

Is there a problem with:

• Powder too old (manufacture date 1999) – sorry, I can’t find any HS6 or Autocomp – need to use whatever I have now

• Do I need more powder to get more gas (for the comp)?

• Any other suggestions?

Thanks for everyone’s help in advance.

What is your powder load using 135 g bullet?

I have the same question but in .40 - I am waiting for my SJC Open Glock (for the last 5 months) and was told it should arrive soon. .

Probably looking at Autocomp as well... but not sure of OAL and bullet brand.

Any one have info on the load? Thanks in advance.

I would use a light 135 gr. jhp Nosler/Rainier. light bullet more powder, makes comp work better.

+1 on silver - since you Open is silver in color.

I have the same one on my STI for Limited.
