30x47 Lapua loads

[the long shot]

I was wondering if anyone has used benchmark powder for 30x47 or another powder. I am probably going to use 118-7 Bibs. Any suggestions?

I run with between 41-42.5 gr. of either IMR 8208 or AR Comp. Both shoot to about the same spot, click or 2 in any direction. I have also used IMR 4895 but I am not near my notes right now.

N133, Benchmark, H322, the various 8208's, 2015, 2520 and even 748 all are proven powders in the various 30×47's size cases with bullets from 112 to 135 weight. -Al

I've been using N133 in my Jag 2 which is a modified 30x47 for years with good results at quite a few score matches. I just started using that caliber after laying off from using it for about 3 seasons. It shot well enough at a short range IBS state score match on Sunday at 200 yards in VT to finish 3rd by getting creedmored out of 2nd. Years ago a lot of people were using N135 in that cartridge. That was the go to powder for many years in the Hunter class. I probably have around 50 pounds of it in 4 or 5 different lots and I tried to make it work and it never shot as good as 133. With a 2001 lot of 133 I was using 43.5 and was using at the time a 112 Bart and at the time it averaged around 3205 fps. I started out with that lot of powder then I ran out of it before finding some more and I had to increase the powder charge by a half grain to 44. I talked to Randy Robinette at length about the 30x47. He was surprised he said that I was using that much 133 because he said that he couldn't get that much in his case. He said he had good luck using H322 in his. I found out one thing not to use a 205 primer with that much powder in my case. It just didn't perform. Went I switched to a BR4 primer boy did that make a huge difference. You can see the difference between the 2 primers. I can shoot consistent high zero's to mid ones all day long with that combo. The first 2 pictures are from 2016 when the barrel was new. The last picture is the first time I shot the barrel after Bob Green freshened up the chamber. I had to up the charge to 43.8 to equal what I was avg for speed. It's a Hart 16TW and it had 2223 rounds on it when he did it in May of 2020. The barrel still shoots. I now use 43.5 but with my 115 bullet that I make. I also have tried LT32 in it and that shot pretty darn good also. Something that I learned years ago. All these groups don't mean a damn thing if you can't read the flags and pull the trigger at the right time.

Jim, at one point N135 was the go-to powder in the various 30X47-48 cases.

In the early 2000's, the burn rate of N135 effectively 'slowed down', as did N133. As a consequence, most competitive BR shooters with the 30X47-48 cases moved to the N133 and never looked back. We used a lot of N135 in our 30 WareWolf cartridge over the years ( .165 short 308W on the Lapua 308W case) and also made the transition to N133.

Good shootin' -Al

Yes I knew that about the burn rate of the older N135. I have 90's vintage of the stuff that's why I tried all of the 4 or 5 lots that I had.

I think I was about the only guy in the country shooting N-201 in my 30x47.......

And shot it very well!

I wonder how much SRB is still floating around? -Al

Chad's probably got it all......

 

[AlNyhus]

Yeah....D.B. ran a 'dispensary' long before that term means what it does today.

Hope all is well, partner.

It 2009 to 2004 I shot a bunch of VV-135 around 42.5g with Randy’s 118 10 0’s and had success with a 18 twist pacnor in my 30x47 !
