300 rum reloaders, need some help

[SPAK]

Hey guys,

I have a friend that is going to get started in reloading his 300 RUM. I'm looking for some data on components before purchasing some dies.

Which brass has the most consistent neck wall thickness? Midway has federal, nosler, and Remington. My instinct is to go with the nosler but that would just be a guess. I don't know if winchester makes 300 rum brass, but I don't think they do. Not planning on neck turning.

does anyone know what the average neck wall thickness runs for each of the three brands OR what outside neck diameter runs loaded round with a 180gr or 200gr accubond (non neck turned)?

Normally I would start him off with a lee collet die, but I don't think they make a die without custom work. Otherwise brass neck wall thickness would be a non issue.

Thanks in advance.

I use Remington and have good results. 180 and 200 acubonds for hunting have performed well on elk. I don't have to shoot twice. I don't turn necks anymore, I just don't have time with small kids and more demands at work.

I measured mine and .337 outside neck with 180 ab. I don't have the greatest calipers for measuring just the neck but i was getting .013 for once fired before sizing and .014 for new. I only neck size and haven't split a neck yet but my oldest brass prob only has 4 reloads.

I would pick up some Remington and don't look back. My sako and friends 700 both like hot RL25 loads with jump. Good luck.
