A weatherby bt 150 grain has a 3540 fps what would a 300 rum be in fps?

I can't understand you sentence. But I think you are comparing the two in 150gr.

I don't know as I wouldnt' bother to shoot a 150gr bullet in a big game gun.All I can say isonce built up some 150gr with 4350 powder for the hey of it. Velocity was not good in my gun at 3450fps. But I wasn't after velocity or would have picked a different powder.But thatswhy I have a 308win for deer.

I never suggest people ever trusts too many published data for anything to make a decision on what to buy. Everytime I break out my chrony, people walk away upset.

Every gun and barrel is different. I have had identical calibers, identical guns, identical loads, shoot 100fps different.

Big country,
I guess what I was asking was if a ballistic tip 150 grain weatherby ammo has a projected 3540 fps rating; What wouldlets say 150 grian ballistic tip out of a 300 rum be in fps?

I don't know anybody that loads 150gr for 300RUM factory wise. Sorry, can't help ya.

Remington has a 150gr Scirocco load listed on their website.

300 yards 2762

That is from a 24" test bbl.
