Chopped my 300 to 20in 180 bts 74gns 09 gave me 3000 avg in 24in using same load in the 20in but havnt chronied them but guess about the same as Smiddy accurate to

So i ended up chopping my 300wsm down to 21" and fitted a hardy can. 178amax at 3070fps. Only lost 50fps with the chop.

FYI. 20" 300 saum 168 NBT 2,976fps. 150 Barnes 3,186fps (have settled on the Barnes and dropped .5 grn for 3150)
Wonderfully accurate with both loads.

What powder you using there Thar cheers

2208 for 150. N550 for 168. You saw that its a SAUM and not a WSM, eh.

Sure did thanks dont have either only 300wm 09 has worked well in the past interested to try the n550 works good in a friends wsm with 200elds have to do a trip to the big smoke to get it though have tried 08 but that worked better in the 375h&h with 250grn thanks
