I'm wondering if there is any published data for bullet with respect to how fat the bullet oglive is from the tip of the bullet. Or anyone that knows first hand. I know that oglive is not an exact measurement with different tools used to measure it returning minor difference. For the record i use the hornady tool formerly stony point gauge. 

What i'm trying to do is find a bullet that i can load for my 300 wim mag that will allow me to test accuracy with a jump of less that 0.090 which is the closest I can get right now with my tikka. This is due the the length of the magazine. 

This is a hunting load for ELK and Moose and I prefer 180 grain. 

Regards,

I've had astounding results with the Barnes LRX 175gr and Reloder 22.  I haven't seen specific engineering documents from Barnes, but I too use the Stoney Point.

That mirrors what my friends .300 WM's have achieved too. RL22 is a good place to start with a 180gr bullet.

HOWEVER...my VERY fickle .300 WM Sako preferred IMR 4350 with a 180 grain Barnes Triple Shock bullet.

if your rifle wont shoot the 180gr sierras, either the pro hunter or the game king sbt, then i wouldnt shoot it.

Just make a dummy round you can use to measure your OAL with either calipers or even better, a comparator.

Step 1: Size a case.
Step 2: Seat your chosen bullet intentionally "long" without any powder or primer in the case.
Step 3: Color the bullet with a Sharpie marker so you can see where the rifling lands starts to engrave the edge of the ogive.
Step 4: Feed dummy round into chamber. If bolt closes easily, your bullet seating depth is likely too short. Check for marks made by the lands. If too short, load another dummy round with longer OAL to ensure contact with the lands. If bolt handle doesn't close with reasonable force (don't force it), eject the dummy round and keep seating the bullet incrementally deeper by a few thousandths at a time until the bolt JUST closes with some felt resistance. You should have very slight land marks on your bullet. This is your max OAL for that bullet in your rifle. When the bullet is just kissing the lands, you will need to measure OAL over the ogive with a comparator, as there is more OAL variation over the bullet nose than when measuring over the ogive. Just use the same ogive comparator or seating depth tool each time.
Step 5: If you gotta jump to the lands (mag box length restrictions or your rifle seems to shoot better with a jump), set back the bullet from there by the desired amt.
Step 6: Save the final dummy round to setup your seating die later by running the press ram all the way up with the dummy round in the shellholder, then screwing the seating stem down until it contacts the dummy round's bullet ogive without seating it any deeper.
Step 7: Go kill stuff and live happily ever after.
