.204 / Varget / 39SBK

[chuckw2]

Guys,

Are any of you loading Varget in the .204 with Sierra 39 BlitzKings?

Varget is a little slow for the .204. A 100% load density yields only ~47,000 pressure @ a bit over 3600 fps.

Most folks are having great luck using the 39's with either 10X or H4895.

Mike that is exactly what I am getting, 3645 FPS with 28.3 grains of Varget. Load density is 100%.

The load shoots great, also the fact that I have 24LBS. of Varget sitting around made me want to give it a try..

I think I have a little 4895 left...I will try that next...


Thanks very much for your help

Mike-What is 100% load density? Is that where it is just before being a compressed load?-Steve

Steve,

Short answer is yes to your question. It will vary ever so slightly depending on the actual case capacity and seating depth.

I just used the numbers from my .204 in the example, and have the data in Quickload.

A 40gr Vmax with 28gr Varget in Winchester brass and Remington BR primers showed 3857 on my chronograph from my LRPV, I didn't get to see what the 39BKs would do yet.

The Hogdon data says this should be about 55,100 PSI. They say it should be 3647 from a 24" barrel. I suppose my results are close since I have a 26" barrel.

This load shoots pretty good from my gun, everybodies experience will vary. I haven't settled on the ultimate load for this thing yet.

What about RX-10x?????

I would definately suggest that you try H4895!

In my Kimber Pro Varmint,22 inch barrel), the 39gr Sierra BK & 27.7grs H4895,Hodgon Maximum)gave me an average of 3873 fps for 5 shots. Actually, 2 of those rounds fired chronographed over 3900 fps,both were 3910 fps). This load generated no pressure signs at all.

It would be interesting to see how further I could go before I strike pressure signs, however I may just keep to this load from now on. Velocity and accuracy are impressive!

Hodgon say that this load generates around 55,000psi and according to their data 27.7grs H4895 behind a 40gr V-Max gives 3774fps in a 24inch barrel. I get an increase of 99fps in a 22 inch barrel.

I also found that H4895 was cleaner burning than BLC-2 I was developing loads with and produced less muzzle flash. 3673fps was the highest velocity I obtained with 29.8grs BLC-2, though the SD of 5 shots was very good and the accuracy about the same as my 27.7gr H4895 load.

Regards,

Michael.

My best load so far has been with 27gr of Varget with a 40 Nosler B tip, I only have 7 pounds of it. This load has produced more than 1 one hole group for me in my HS Varmint rifle. That said I can get a one hole group with factory 32gr Hornady cartridges. FS

I get very good results with 25 gr of RL-10X with the 39 gr blitz

 

[shooterjon]

Yes my Remington VSSF II likes Varget-27.6 grs with the Sierra 39 gr BK in WW brass and a CCI bench rest primer.This combo gets me 3680 fps Chronographed and shoots consistently 1/2 " to 3/4' groups at 200 yds.

I've tried 10x, RL-15, and BL-C,2) powders with luck. BL-C,2) seems to be the ticket for the 39 SBK. The 40 gr Berger shot best with a stout dose of RL-15.

 

[Ogre6br]

all my mates who load for a 204R say that H4895, and our local EQuivalent powder) is the go with 39 BK's
