Thread: .270 Projectiles Lagging Behind

Soon to take delivery of my first .270 and looking at available projectiles, the highest BC I can find is .536 for 145 ELD-X. That’s reasonable, but lags well behind the 6.5, 7 mm and heavier .30s. There can’t be any reason for this than underinvestment by manufacturers. Come on Hornady, Berger, Sierra etc, please try a bit harder for us .270 (and WSM) followers.

Any advice out there regarding other offerings (not LRABs).

Cheers

170 Berger hybrid hunting .662 (1:8 twist required)

150 LR accubond .625

140 cutting edge MTH .590

130 cutting edge MTH .540

145 eldx .536

150 vld Hunter .531

140 Berger classic Hunter hpbt .528

150 interlock .525

150 interbond .525

How far are you trying to shoot stuff? All those projectiles (and plenty more) provide more than enough oomph when launched at 270 speeds for a very long way out.

Was playing round out at farm a couple of weeks ago, just verifying rangefinder and dial-ups, at varying distances..
So rangefinder values dialled in to my VX6 at 200, 300, and 400 yards were spot on. My mate then said that from the top of the terrace to the gong is 940 yds."See how good ya are"
I set up with the bipod, dialled in 940 yds, first shot missed so allowed a little more for windage, and proceeded to hit the gong (300 x 300) with the next 3 shots.
Nothing wrong with the .270 out to stupid distances, and this was with 145Gr ELD -X

The tested .591 BC is whats called a midrange or 200yd BC, most new bullets including the eld range are now publishing data from this testing to more accurately reflect the calibres they are shot from, they will usually also show a higher and lower number as a verified bc at a certain velocity. Most apps will allow you to enter all 3 numbers, the 150gr ablr I use(d) being .625 .569 and .531 which was bang on out to 900yds in my wsm

"New" web page data says .591
Even the 165 grain LRAB is only listed as .620

The reason for the lower BC bullets is that the vast majority of 270's are 1 in 10 twist so anything more than 140gr is borderline to stableise

I shoot 170grn projectiles out of mine into tight wee groups...but they are too plurry good for poking at paper,it did same with 160grn lapua megas and every 150grn projectile tried...and its a 80s model 70 without controlled feed 1:10 twist.....try telling my rifle it wont stabalise them.

Yes all 270s will stabilise the old shorter style projectiles including 150's, but it's those new long high BC ones that cause the problems for a lot of rifles.

Thanks fellas - good points and perspectives.

As I said, the .270 offerings lag behind the 6.5s and 7s, but are plenty good enough for most and certainly for me. I just bought a .270, so I’m joining the club, not knocking it.

270 the new ‘best caliber’ !
I’m still struggling with this but loving shooting mine

@Spitfire, why do you want to shoot a super high BC bullet ? If your rifle is for hunting then in all reality the 270 is a 400 metre gun to still have 1400 - 1500 FP energy at that range.
I have just started with the 140 AB in my 270. Since buying those I discovered that Nosler makes a 140 gr Partition. Very likely that bullet would be the best hunting 270 projectile there is.
If you go with a soft bullet like the ELD-X a lot of meat will be ruined and wasted. The balance is quick humane killing at all ranges combined with maximum meat recovery
Remember a lot of the new high BC offerings are made for WSM's and not 270 Win
