7mm Remington speed with 150 grain Ballistic Tips?

[Lonnie]

Well, I decided to go with the 7mm Remington Magnum for a variety of reasons. What I would like to know, what is realistic speed I should expect in a 7mm Rem Mag, shooting 150 grain Nosler Ballistic Tips in a 26 inch barrel. Gun will be custom Remington 700, Broughton barrel.

Thanks

Im just guessing, but somewhere around 3200fps. I was getting 3250fps out of mine with 140's and a 26" tube.

According to Nosler you could get 3,250 ft/sec with a max charge of IMR4350. Their test rifle had a 24" bbl.

The average max velocity with other powders ran about 100 ft/sec less, give or take.

Should be in mid to upper 3200's. I get 3240 with 24" tube.

3150 ft/s in a 24 ".

A 5 C or a 5 R barrel may give you more vel.

I have an unfinished 7mm barrel blank that is 29.25 inches long. It will finish up to 27.75 inches long. What kind of velocity would 150 gr BT's get in a 7mm Remington mag with a 26 or even 27 inch barrel? Would it be getting close to the 7mm STW speeds with a long barrel?

I forgot to mention that the barrel is a Broughton 5c barrel. I like heavy guns, and the barrel is a light varmint contour.

Lonnie,

Hopefully this is on topic. In my 28" Douglas 7-.300 Weatherby I got 3,525 feet per second with 150 Nosler Balistic Tips. It used 85 grains of IMR7828. With 80 grains of H4831 and 77 grains of IMR4350 it achieved 3,400 fps.

Unless you have an abundance of 150 grain bullets, I highly recommend 140 grain bullets. I shoot 2 7MM guns with fantastic results Lou

The 150 BT is my "go-to" bullet in the 7mm mag:
