Mag is restictive and I have bench buddies that shoot 300 wsm off a 270 case with better shoulder and same 200 grain bullet with better results,bullet selection poor. I do like the rifle for timber hunts,but would rather have one of my 338 normas
Thanks for your experienced comment! MontanaRilfeman suggested almost the same than you did, so the 325 WSM is kind of a one - way street. From what I know is there still hope for the good 8mms like 8 mm RM, 8x68S and others. In the USA, Hornady starts doing a good and promising work on the 8mms. At last they came out with a new 323' SST with 175gr. for LR and later on there will surely be a 220gr version of it for the hotties. The same thing can be watched in Europe, good bullets are to come and the 8 mms finally will get the high ranked place they deserve.

Re: 8mm Thread

the 8mm Rem Mag has long been a favorite, having loaded for it for many years and having seen it's accuracy and ability to dump large bull moose and brown bear in Alaska has me convinced it needs more attention than it currently has .. back in 2000 I had several wildcat schemes going and one of them was the 8mm-300 RUM..... naturally, the lack of high BC bullets killed the dream...and I ended up with my smiths version of a 300 RUM AI ( similar to 300 Tomahawk) and a hand full of 300 RUMS, 7.82 Warbird and later a 338 Edge

This time around....... as an additional barrel to my current project.... I have necked down my 338 Pro to 8mm ( 338 Norma Mag parent case)

.342 neck length and a 35 degree shoulder yields case water capacity at approximately 108 grains
(quick design estimate) 14.5 more grains than the 8mm Rem Mag and 23.1 gr more than the 8x68S RWS.... the shorter fatter case will be perfect for running the heavier bullets without impacting powder space... the throat/ leade will be set to run the bullets to seat at the base of the neck/shoulder and still cycle through my rifle set up with AICS cip detachable mags.... the Rem 700 platform is perfectly suited for this wildcat cartridge........
this effectively recreates the power I envisioned with a 8mm-300 RUM years back........ all dimensions are being reviewed and a reamer will be ordered for my newest wildcat the

"8mm XIPHOS"


the Xiphos was a short sword use by the ancient Greek Warriors the Spartans with deadly effectiveness...... as seen in action in the movie "300"
it means simply ...... penetrating light.....

+! I was using an 8x57IS (Mauser) over a long time with best results on game, it never let me down. But, this round wasn't made for LRH! Out max. to 300 m. Nowadays I'm mostly using 7x65R and 300WM. Currently I've been completely intrigued by the 8x68S and will have one build in 2014 parallel to a 7 RM. The 8x68S is easy to reload (important to me) and has plenty of perfomance which is more than sufficient for all European game and plainsgame in Africa. That's good enough for me so far.

Wow! Really, that's about rocket science! I'd love to see this gun in action.

The film was great, I loved it, and this particular round also will be! I wish you the very best with your project and please hold me updated!

Re: 8mm Thread

Sorry about the quote thing! Have to take some training I suppose. Made a mistake, but my thoughts are hopefully clear.

LM-102

Very high BC Bullet for windy long Ranges


LM-102, 55 mm long, 16 g heavy, BC1000 1,219, for 170 mm Gain twist barrel


That's the actual (brass) bullet for the 8x68 Taras delivering 1985ft/s at a distance of 1200m/1312yd. 323' LR - bullets on their way forward.

Interesting... it looks a lot like a GSC bullet. Interesting tail

Re: 8mm Thread

Thanks Mark! Here are some informations about lead - free bullets which I was posting in the current Barnes thread. Unfortunately it seemed so far not to be of interest.
My post includes data for the 408 Cheytac as well and of course 8mm (323') . This new rifle G -6 in the brand new 8 x70 is currently tested in Norway. It's based on a Christensen system and has a GRS - stock. They were already shooting out to 2000m ! That's quite a distance. I'd also like to hear the opinion of Broz about this development.

Lead - free producers like Barnes and others will come under (big) pressure since the development of lead -free bullets for the exclusive purpose of LR has already made big steps forward.
The Lutz Moeller Company in Germany has developed two different kinds of LR - bullets for the 408 Cheytac made of brass. Chey Tac 1021 with a 26g/401gr bullet weight and the 1022 with 30g/463gr ...!! Both hold a velocity of stunning 549m/s or 1801ft/s at 1200m/1312 yards. You'll find loading data on his web sites also for American powders like RL 22, H 4350, H 4831 and IMR 7828.
Under a project called G-6 (Gewehr 6/ rifle 6) Moeller develops a special LR - round LM -101 (100% brass) for a... .323 round, the brandnew 8 x 70! In addition the G-6 gets an interchangeable barrel for 338LM. This barrel in 338LM is thought for "low cost" training sessions. Looks like that thinks are getting better.

BC1000 for the Cheytac 1021= 0,95 and BC1000 for the Cheytac 1022 = 1,069
