Re: 7mm reloading

Is the twist rate on the BDL fast enough to stabilize the 162 and 168?

If you do this in a bdl you will likey be jammed into your lands. You might not be able to eject a cartridge ( at least not the bullet and some of the powder). Your pressure may spike. Always find your lands and measure from there, you need to know if you are into them as there can be consequences. Once you know where your lands are, you can see if it fits in the mag, then adjust from there. Some rifles (Tikkas, Brownings, Weatherbys) your mag will be shorter than your seated distance to lands. The BDLs I have experience with will easily reach the lands before I reach Magazine length (Including a 7mag with 168 VLDs).

Haven't tried a 7mm RM in a 700, but my 7mm STW is way past mag length before it touches the lands...Same with my .308 Win. Both BDL floorplate setups.

Weatherbys have freebore, you most likely won't be able to even touch the lands unless you have a rediculously long bullet, or the bullet is barely in the neck.

Browning A-Bolts have short magazines, so seating them just inside mag length is nowhere near the lands.

I have, and have had numerous 700's, Brownings, and a Weatherby, and all seem the magazine is alot shorter than the distance to the lands. Both short & long actions.

Just my experiences.

Re: 7mm reloading

The 7STW is a very long case (2.85"). The 7mag case length is 2.5". Almost 3/8 of an inch is a huge difference when we're talking bullet seating. They both have the same mag length.

Re: 7mm reloading

The new bdl's, sps's, etc.. have a 3.71", so .010" short would leave nothing but the boat tail of a 168 Berger in the case of a 7mmRM, if you have a comperator the saami spec freebore on a 7mmRM is .135", M700s usually have about .020" more than saami, 3.425" should put you just off the lands and I suspect 3.445" to put you .005-.010" in the lands, good luck.
