longrangehunter · 2025-07-18T14:10:54-0700

If someone can help me out that would be great!!

6.5x55 Swede 18.5” bbl.
Lapua brass
127 LRX, Nos 125 and 140 Partition using
Norma 204, and URP.

Norma lists the 140 Partition, it would be interesting to see how QL compares.

Appears that the URP will be just a little more efficient.

Thank you very much Dr. Mike!!! Much appreciated!

Hopefully one of these will come together and be consistent enough that I’d hunt with it. I only have on hand one other bullet that’s easy to make shoot, the Green Boxed 140 GK. Partitions tend to be fairly easy to get to shoot, and a better bullet then anything else to boot too!

It’s those first, after that I have some Norma 143 BondStrikes.
