Need help identifying these cartridges.

Could it be a 6mm BR-DX or 25 wssm?

 

[cfvickers]

It is a BRX

 

[barnesuser28]

ok.

 

[cfvickers]

See you made me start doubting myself, but I proved myself right this time. a 25 wssm has a case head/rim diameter larger than a 300 H&H Mag. If there is/were something called a BR-DX it would just be the dasher. bot the BRX and Dasher are improved versions of the 6 BR

The 6mm BR-DX does exist 6BR Improved Cartridge Guide within AccurateShooter.com third one down, it doesnt have a 30* shoulder though so it is out, i didnt realize that before.

I think the BR-DX is the Dasher. I was thinking DX stood short for Dasher improved.

I looked and I stand corrected. it is very close to the dasher though. The one listed is still a BRX in my opinion.

The correct answers were: 4.6x30,22 PPC, 6.5x55, 300 H&H, 30-378 WTHBY, 9.3x74R, 416 Dakota, 505 Gibbs

Well had I gotten the first one right I would have been right on the third. I knew that 6.5x55 looked like a 6.5x55 but the 6.5x50 has about the same angles. that 22 PPC didn't seem to have enough body taper in the picture for a PPC. When I looked at the dimensions of a PPC against a BR or BRX I determined BRX based on the taper, or lack of and the shoulder angle. I considered all of those except the 4.6x30 which I have never even heard of, and that is odd, because I have at least seen something written of just about any cartridge I see. Learned something new. Thanks for updating us!

 

[barnesuser28]

I also have never heard of the 4.6x30, it took the guy that got it right like 30 guesses at least to get it right.

 

[cfvickers]

Had time for further inspection on the measurement and vis comparison chart. I STILL say the second is a BRX. Too fat and too little taper for a PPC. I will buy that the 4.6x30 is that. and my first instinct was that the third was a 6.5x55. did they show a picture of the case head markings?

No they didnt.
