[QUOTE="jweigel, post: 2587620, member: 72021"] Vihtavuori 500 series powders give lots of options. You want to pick the 500 series powder that best matches the bullet weight for caliber. N570 achieves amazing results with 190 grain and heavier in a STW. Same with a 180 grain in a standard RM. If shooting 180s in a STW I would drop to 565 and with 168s down to 560 or even 550. I personally have not witnessed any temp issue with 500 series powders, but that's just me. At least no worse then Retumbo or 7828 SC in the same summer heat of winter arctic cold. I subscribe to the heaviest bullets for caliber to better overcome wind and more lethalness farther down range. IMHO....weight overcomes speed with modern high BC bullets. Again....this is just me. STW= 195 RM = 180 264WM = 156. Most all these "older" designs have to slow of factory barrels but when barreled to match new "modern" calibers like 28N or 6.5PRC...they hold there own or even still are KING! jjw ND [/QUOTE]
