The hybrids are very forgiving in regard to seating depth. I personally would run at a tried and true jump of .040 and run a ladder of ~0.3gr charges. Quick easy and can be fine tuned down the road.
This quickly gave me sub 1/2moa w/ my 300wm.
Mine is a sporter also. About 3 shots is all it can handle at a time. Just let cool good inbetween shots and groups. Still shoots bug holes and light enough to pack around but sure has kick even with brake. I learned on that one no more sporter bls in magnums.

Agreed but I would start with .015 jump.
No, I completely get your point and I by no means think you are wrong. I simply state .015 because I would like to not adjust for throat erosion and this is what Bryan Litz suggests. I have not killed any elk but I've shot plenty of 215 bergers through a 300WM.
I'm gonna go out on a limb here and say throat erosion will be the last thing to worry about in a .30 cal hunting rig. Granted he doesn't shoot the living crap out of it. I can't imagine one would find pleasure in high volume banging steel or cutting paper w/ a sporter barreled 300wm pushing 215's, sounds like a recipe for a flinch.
I obviously can't speak for you guys but you do not get proficient at long range shooting with your rifle in the gun cabinet. I shoot my rifles. A couple of points. First throat erosion can typically be measured within twenty rounds and only gets worse from there. Second the demise of a barrel is almost always due to the throat which is why many set back and rechamber. If I like my current 300 as much as I believe I will I will most definitely burn the throat out and its even nitrided. You may not chase the lands prior to you rebarreling but I can assure you it will have throat erosion. This is a long range hunting forum. Only unethical people would develope a load and stop there until hunting time. It takes time and rounds down the tube and in field conditions to take ethical shots at over 500 yds on animals. Ohiohunter and Gord0, I am completely dumbfounded by your posts.
