Ben my loads to date with the 450grain Woodleighs in 416.

90 grains of AR2209 2250fps
93 " AR2209 2310fps

103grains of AR2213sc 2370fps

As to one of your original questions about would I use them, Yes and No. Hows that for a bet each way. OK what I am thinking is this. If I was going after just DG-not cats- I would as long as I could get them shooting to the same POI as the Woodliegh solids or Hydrostatics. Yet to check this out. I would think that a 450grain 416 pill at 2300+ fps could be as an effective stopper as a 500grain 458 at 2100fps. Just s thought. Those with some experience in this area might like to let us know their views on this.

However if I was going after DG and plains game I would stay with the 410 grain pills as the shoot to the same point as the 400 grain Hydrostatics and I could use the 400 RNSP Woodleighs on plains game out to 300mts if I had to.

Yet to have a play with the 340 Woodleigh's to see how they group and where they land compared to the Hydros and 410RN.

Cheers
