No joke I shoot the same in .300 WBY. I've just never had all these problems with a pass through such as others seem to have... and I've never shot a lot of bonded bullets at Whitetails. I'm just shooting Sierra's most of the time.

I read all these posts on every forum on the internet about needing bonded bullets, etc. Sometimes they have me even second guessing myself and I think I should go work up a better load with a Partition or something. Then I shoot a deer and blow the whole front undercarriage out from under it and I'm sitting there dressing it thinking how could everyone else be having the issues they are having?

35 whelen with 225gr Sierra btsp, boom flop, no runners.

Whatcha loading under that Sierra? I use 4064 under a 250 gr Hornady RN in my 35 Whelen AI.

I have some 165 SPBT sierras coming to try in my 308 as I type this. I have been reading the 'gloom and doom' about them on the net for the last few days, and I've come to the conclusion that the vast majority of the folks who are claiming bullet separation and disintegration also said their animal fell in their tracks, or took three steps and fell over. If the sierras will do that, then I don't really care whether the jacket separates internally or not.

I just want an accurate bullet that will do the job, and don't cost $50 for a hundred. I believe the sierras will accomplish this with no fuss.

You will not be disappointed. Sierra makes good bullets that will create a large wound channel. Bullets may not exit but you will have a nice souvenir when you gut the deer that died in its tracks.
