30br vs 30bra

Sometimes I think UBR is like the red headed stepchild farting at the dinner table of Benchrest. IMO, it does not get promoted as much as it should by the powers that be. It is a lot of fun and highly competitive.
I agree, here in KY it is very popular and also agree that it is highly competitive. Excellent shooters across the board. Always a good time.
I still have to tweak a load for my grandson, he will be shooting in the Modified class. This will be his second UBR match.

Real world comparison....30 BR 34.7g H4198. 30 BRA 36.4g H4198. Same powder lot, same 8 in drop tube, same 114g short BT bullet just contacting the powder level, same 8-10 jam, and same reamer FB length. There is indeed a faster node, but I agree with Wheeler that the main advantage is the 40 degree shoulder. No chrono data .....I only care about where the holes are.
Yes,
I am right at the same powder weight with my 30BRS with both H4198 and the N-130 so far with my testing in this particular rifle.

Has anyone tried shooters world buffalo rifle with these cartridges?

For cast bullets it's been my goto replacement for H4891. Of course I'm comparing apples and oranges, but I would try those oranges to see if they would work in the BR/BRA cartridges. I just don't happen to shoot those. However, I have Oodles of SW buffalo, so if it worked, I may just give the BRA a go.
 
Since this thread started, I have revised my powder selection for my 30BR.

Before the Nationals, I was locked into 4198. However, just before we left, I got some N-130 to try. It shot great at 35.6 grns.

When I got to Raton, I had three powders with me, figuring the 6000 ft elevation and lack of humidity would mean some serious load development. H 4198, LT 30, and N-130.

On arriving, I decided to stick the exact same N-130 load in my Rifle that worked on the Gulf Coast. It shot great. So good that I decided to simply go with the N-130.

I had a good Nationals. My Rifle shot really well.

To heck with 4198.

Are you using 35.6 with 118s?
Only shot a few groups with that charge weight, but my 30 seems to like it with 118s.

I will have to switch powders soon. Is N130 better than LT30? In the straight 30BR ?
