Re: 300 SAUM load advice.
Thanks very much for all the information. This will be very helpful when I start loading for this rifle. Rifle season is getting pretty close here in KY, so today I slapped a 3.5-10x40 VX3 on the Sendero(I will switch to a 6-18 VX2 during load developement) and plan on trying some factory stuff to sort of break in the barrel, and maybe get it shootin good enough to carry it a few days.
While I was cleaning my barrel this afternoon I descovered a small dent in the crown, does not look like it is effecting the rifleing, but I will not know until I shoot. I hope to be able to shoot a little sometime this week, I will let y'all know how she does.
sewwhat89, have you had any luck with R22? or IMR4350? H4350 should be pretty close right?
