30R BLASER - Powder Choices

[AKMATT]

I have been waiting for a while for folks to share more information on powder choices for the 30R Blaser cartridge. Not much to see so far other than Reloader 22.

Can anyone with Quickload recommend 2 or 3 powders that are relatively aesy to find in the US that would be suitable for loading either 165 or 180 grain projectiles? I would appreciate any help I can get.

No idea but with ballistics similar to the 30-06 improved would that be a good start?

It seems that there may be a few people trying to realize the potential of the 30Rs case capacity by loading it to bolt action pressures.

This might be fine with the jager block equipped K95 or D99, but not so smart with the BBF/BS/BB.

I am not in the head of either Blaser or RWS, but it seems to me that the 30R has been designed with the goal of offering a tad more speed than the 06, but at significantly lower pressures, so that it can be used with a healthy strength/safety margin in non jager block break actions.

I don't see any real need to be concerned about the lack of data. I would do as suggested by mchughcb, and start low with either 06 or 06AI start loads.

Given my thoughts on pressure levels in this cartridge, I would probably look at H4350 or H4831SC with those bullet weights. RL22 seems to me to be a choice for stoking it up as hard as you can, which would not be my approach if I was fortunate enough to own a 30R anything.

Going to wait until theo gets his before we test it properly.

I have heard this cartridge described as being the rimmed 30-06 AI once or twice. Capacity wise isn't it almost identical to a 300 H&H? Shouldn't those powder/ bullet combos be very close and therefore- pretty good choices? Let's change one variable and say, "I will be shooting this in a falling block action like a Ruger No 1." If the capacity in a 300 H&H is the same, then using the same powders and expecting very similar velocities and pressures in a 30R should be a reasonable conclusion. Am I missing something in my thought process?

Reading from DEVA data, easy to obtain powders(?) such as Win WMR and IMR 4831 are listed as able to be used with 150, 165 & 180g bullets;

150g 68g IMR 4831 935 m/s
165g 64.5 g IMR 4831 864 m/s
165g 65g WMR 842 m/s
180g 63g WMR 815 m/s

however R19 and R22 are the speed demons, e.g:
180g 65.3g R19 851 m/s
200g 61.6g R22 808 m/s

Given IMR4831 / H4831 sits between R19 and R22 according to this http://www.adi-powders.com.au/handloade ... alents.asp it wouldnt surprise me if it has potential with 180 and 200g bullets but just hasnt been thoroughly tested and written about. From an Australian perspective, 2217 has caught my eye as a candidate for this cartridge.

Lets face it. If you aren't using 220 woodies you might as well use a 308 and stick with 150 corelocks?

[Gun Barrel Ecologist]

Btw, case capacity of the H&H is 10g more than that of the Blaser case

[Gun Barrel Ecologist]

Lets face it. If you aren't using 220 woodies you might as well use a 308 and stick with 150 corelocks?

Depends what you are shooting and how far out, there is a process of demonising returns with 200g+ bullets in 30 cal, high SD but less ftlbs where you need it than a higher BC 180g... Look at the history of the .30'03 vs .30'06...

But then again, I load 181g Tugs in the .308

[mchughcb]

If you had of asked me a year ago I was happy with the 180gr but since I lost a few sambar and converted to the 220gr woodies, what a difference that has made.

[Gun Barrel Ecologist]

Did it coincide with reading "Green hills of Africa"

I would have just opted for a bigger diameter bullet

[mchughcb]

Not in the K95 stutzen I won't. I value my shoulder

Looking at Quick Load the various 4350's, RL17-RL19, URP-N204, W760 or powders in similar burn range look to be the best with charges in the high 50gr to low 60gr charge weights.

I hope this helps.

Thanks for the table Dchamp. This was what I was looking for. I will see what powders I can find on a regular basis that are of those you listed and give them a go. I have never seen MRP powder. Does that have a US equivalent?
