[QUOTE="woods, post: 282324, member: 6042"] Picked up a 300RUM Sendero and need to start some loads. I have Remington cases and have received the following dies RCBS Neck Sizer Redding Body Die RCBS Seater Lee Factory Crimp I have taken the expander ball out of the neck sizer and it sizes the outside to .332" and have outside neck turned the brass down to .0135" thick which should give a grip of .003". So now to stretch the brass I would like to try 180 gr TSX 200 gr Accubond I can load the TSX to within .060" of the lands and still fit the magazine but the 200 gr Accubond is going to be .110" out. Seems to me the appropriate powder would be 180 gr bullets - RL22 200 gr bullets - RL25 both of which I have plenty of. I also have plenty of H1000, IMR7828SSC, H4831, IMR4350, RL19 and IMR4831, all of which are possibilities. My Nosler #5 shows 87 gr RL22 as the max load so a possibility would be 180 gr TSX - 85 gr RL22 180 gr TSX - 86 gr RL22 180 gr TSX - 87 gr RL22 But for the 200 gr I have no listing for RL25. If I wanted to guess I would say 200 gr AB - 85 gr RL25 200 gr AB - 86 gr RL25 200 gr AB - 87 gr RL25 Should I use the IMR7828SSC instead with the 200 gr AB? This is just stretching the first 25 cases but I would like to start at a meaningful powder charge but still be well within safety ranges. What I'm looking for is someone who has gone through the development stages as well. Good to go? [/QUOTE]
