Thread: 300WSM loading options (homework)

make that a .277 150grn NBT
muzzle of will go 2800 cause its bit heavier.....400 yards 2107fps and 1479ftlbs with 22'' drop from a 200 yard zero

and just for grins n giggles cause its easy enough with manual open in front of me

will add in 160grn partition at 2700fps...cause that figure follows same curve/line of 10grns projectile = minus 100fps velocity

BC .434
muzzle 2700fps-----400yards1932fps and 1326ftlbs with 25'' drop from 200 yard zero

now IF you could push that flying brick of a160grn partition at 2900 at muzzle it would be snapping at heels of the fatter 168grn .308 with said same 21'' drop and 1564ftlbs energy retained

all in all there is not a huge amount in it bud.....

I agree not a huge amount in it, it's about making the rifle nicer to carry and shoot off hand by shortening the barrel whilst keeping the same or close to it performance. In the case of the heavier 30 cal pills it is and only ever so slightly better performance out of a shorter barrel. if I was only doing it for projectile performance and ballistics you're right not worth it/much in it, but when you add that it will make the rifle nicer to carry, travel with and shoot off hand these are the factors that I'm looking for.

I think you missing my point still bud......I dropped velocity from what you getting now at 75fps per inch removed.... so you DO GET the nicer to carry and shoot off hand thing,while still having terminal preformance more than ok..... pretty sure you not going to drop 75....depending on cartridge it can be as low as 25fps... 75 was worst case .... but you big boy and know what your doing...Im only trying to point out how green the grass is on your side of fence before you risk your knackers climbing over the barbed wire.

I do get what your saying.....but the 300wsm will still do it better, won't be turfing the 270 barrel or components till new one is proven....or disproven
