.308 Win Reamer Suggestions

Obermeyer chamber works just fine with Jugs, I even shot them out of a 13 twist.

How do you think an Obermeyer chamber would do with 185 Juggs? Could possibly see myself shooting them after reading how well Wheeler likes them for hunting. This would be a mag fed 700 BDL.

Thanks for all those PDF's! Really appreciate it!

The limitation is magazine length as you go to the heavier, longer bullets. To fit in the mag, the bullets need to be seated deep, taking up powder capacity. The Juggs have a longer ogive than a Sierra 175. What that means is that when seated to magazine length the juggs will be jumping farther than the sierras.

As far as accuracy/precision goes, the Juggs will shoot great out of an Obermeyer chamber. But you may find that the most accurate load ends up being longer than your magazine.

Thats why I used the .170 FB available in the FTR Reamer for the 185 Jugs in a 12 twist.
Works real well for me. ( I single feed as well )

you seem to be mixing apples and oranges.
mag length ammo and long single fed ammo bullets
the two do not mix well.
if you are going with a mag fed rifle then ONLY LOOK AT BULLETS USED IN MAG FEED AMMO.
I SHOOT 175'S FROM A MAG. and LAPUA 185'S SINGLE FEED

generically
if you load a sie mk175 to 2.8 oal you have 47.8 usable case volume,
if you load a 185 jug to 2.8 oal you have 46.0 usable volume, a loss of more than
1.6 when you are trying for 1k velocity...not a good thing

I’m not afraid to go with an extended Wyatts BDL magazine kit, I did that on my win mag and I can seat bullets to 3.800”, they make a short action version. So I could run an Obermyer chamber and seat bullets long and still feed from a magazine. Little mill work on the stock and you’d be good to go

Not looking for 1K velocity for the juggs. If I’m shooting game at 1K the win mag with 215 Berger’s at 3K FPS comes out. 600 yard velocity I’d be happy with

Pic is exit wound with a 215 Berger at 1,034 yards. Conditions and setup were absolutely perfect.

What is you OAL with the juggs? And what is the jump/jam that works for you?

I dont recall the OAL with Juggs...only measure the BTO anyway...Currently Shooting the 175 Berger LRBT with RL15 @ 2.261 BTO with -.045 from soft jam. ( Think around 2.870 Coal )..but dont hold me to it. ( About )
They fly real well ( Have nothing loaded to measure except 175 SMK @ 2.940 Jam ) I jump them .088 around 2.852 Coal
The Juggs i seat -.028 -.030 from jam

Obermeyer would be an excellent choice.

Agreed
