6.5X300 Win Mag not short

[Blygy]

Hi all.. I'm wondering if anyone has any data on a 300win mag necked down to 264. I'm planning to shoot 142-160 gr bullets.

Any thoughts???

Thanks

ibeleive that is the same item as a .264 win mag.

264 is the same case As 7mm rem mag and 338 Win mag. the 300 win mag is a longer case.. but I can't tell you how much longer off the top of my head..

3 mm longer, or .12"

Any noticeable performance increase over .264WM?

to be honest I'm still waiting on components.. The trigger showed up last week and now I need to wait til I get the scope..The stock is still an unknown ETA..

I'll post once I know more...

Ask Andy, here on the board. He's built one. Call it the 6.5 ARP or something like that. He gets marginally faster speeds than a 264 WM. Try the US869 Powder.

For 3mm of case lenght, I would venture to guess you should save the money and buy ammo to feed the .264WM instead.. getting 100-200fps won't change the world..

OH MY: this is an old wildcat. If you already have the barrel chambered for this, you don't have too many options. It is no better than than the 264 Win Mag. However if you're still in the process of building it, sell the action and find yourself a short action with the 308 bolt face, you have three great calibers to choose from for long range. Calibers are the 6.5X55, 6.5X47Lapua and the 6.5X284 they will be more accurate and give you a longer barrel life. Plus if you ever want to sell it, these will sell. Bill

Give it a rest Bill.The big 6.5 will do everthing Winchester said the 264 would and then some

Case capacity will give you 2 to 4 percent velocity with the same pressures. A little slower then the 6.5-300 Wby. - dan
