First off, kinda new here so please bare with me. I just had a 300 Win Mag built. I am reloading for it and in measuring the distance to the rifling, I have to seat my bullets (in this case Berger 190 VLD) WAAAY out there to contact the rifling. I measured 3.744" COAL and 3.033" to ogive using the Hornady / Stoney Creek gauge. Does this sound right??? Any help is greatly appreciated. Thank you.

yeah sounds about right. if you cant get to the lands with enough bullet still in the neck you may need to change bullets. but lots of people have great luck with getting the Bergers to shoot.

Sounds long to me. My 300 win was built with a Tactical Match reamer that has a longer throat. I don't shoot the 190's but I do the Berger 210 and 215's.

Here are some measurements.

Both bullets seated -.040" off the lands measure head to o-give is 2.855"

The total over all length, -.040" off the lands, of the loaded rounds are as follows.

210 VLD= 3.555"
215 Hybrid= 3.630"

I will add though I could seat the 210 VLD bullets out .100" longer and still have 100% of the neck contacting the bearing surface. That would leave 100% of the case volume available with only the boat tail hanging in the powder area.

Jeff,
How do you like the 215 hybrids? And will those fit in the magazine box by chance? And if you don't mind my asking, what recipe do you use for that load.

does seem like a long measurement but sounds like he is doing it correctly. Thats why I mentioned that he may need to switch bullets if he cant reach his lands and still have shank in the neck. Obviously I dont shoot bergers so my experience is limited but I have tried them a few times. and it sounds like a less finicky ogive or maybe the hybrid is gonna be a winner here

Here ya go. Here isd a very long report for you to read that I did. There should be enough info for you to draw your own conclusion if the 215 is for you.

I use Lapua brass, H-1000 and a Fed GM 215 M. The bullet is seated -.040" off the lands.

I would say you will be fine on box length, that is if it is a 700 REM. If not a Wyatts box will get you there for sure.
