With 24” barrel it is no problem to get 3150-3200+ With 130s and 2950-3000+ with 150s these days. I just used alliant published load data and got just over 3200 fps with 130 partitions and RL16 in my kimber 84l. I went with 1 gr below max as slightly more accurate and still at 3140 fps. One...
The 270 is alive and well. The newest version of H4831 is not the velocity champ in the .270 anymore, but is less sensitive to temperature. That being said, it is still an excellent choice and depending on the manual gives anywhere from 3000-3150 fps with 59-62 gr of powder. There are several...
I have had 3 kimbers - 270 WSM Montana, 300 WSM Montana, and 270 84L Classic Select. All have functioned great and shoot great. I recently sold the 300 WSM, but still have the others. I have bought them all though the years. Apparently there are some lemons out there from what other posters...
The 160 is a semi-spitzer, but it does offer a reasonably high BC (.434) in the range of some "long range" partitions such as the 120 .257, 130 .277, 140 .284, and 165 .30 cal. If I wanted to use the 160 .270 bullet, I wouldn't worry about the shape being too blunt for long range work.

Towsley is about as close to a modern day Elmer Keith as we have (this is not an insult). Towsley is a big bore guy and takes shots at the .270 every now and then. I remember the article, but thought the 140 bonded bullet he mentioned was the Remington CL Ultra and said he was dissapponted...
O'Connor used the 130 weight for most of his work, but often used 150s when heavier game was the only thing on the menu. For example, O'Connor was a dedicated sheep hunter and he liked the flat trajectory of the 130s for that purpose. On the same pack trip for Sheep, O'Connor would bump off a...
Actually, the Nosler Patition was around during both of their primes. I think O'Connor got bullet construction a bit more than Keith did. O'Connor quickly adopted the Nosler Partition for his .270 work, especially after seeing the 130 version consistently exit on game like Zebra on one of his...
Interestingly, O'Connor and Keith were not all that different on caliber capability. What O'Connor & Keith really differed on was caliber recommendations. Let's take one of Keith's most hated, the .270 Winchester on Elk. In one of Elmer's early books he said the .270 killed Elk like lightning...
I have 2 .270 WSMs. One is a stainless M70 that I've had a few years, the other is a Kimber Montana that I have not worked with yet. The M70 .270 WSM has shot everything very well from 110 Barnes TSX to 150 Swift AF. I have had no problems meeting expected velocities with any weight, which is...
My favorite powder for 150s in the .270 is H-4831SC. I generally load 56-57 gr. Generally gives close to 2850 in a 22" barrel and 2900 in a 24" barrel, give or take a few fps depending on your gun and components used.

I guess this is what I'm trying to figure it out. I agree that 7mm bullets of higher SD (i.e. greater weight, such as 160 and 175gr) will have higher BCs than a .270 of lower SD, but I see no trend anywhere that supports that a 7mm of equivalent SD has a higher BC than a .270 bullet of...
WPH,
Similar statements about the 6.5mm and 7mm usually having the highest BC is what got me curious to go looking around. I have seen several articles in the magazines comparing .277 to 7mm making similar statements (i.e. 7mms have higher BCs) and the most common example used is the Nosler...
Nosler Team,
One thing I have been curious about is why your .270 bullets generally have lower BC than bullets of 7mm given same bullet weight or .308 of slightly lower SD. For example, the 7mm 140 Partition and BT have higher BC than the .270 equivalent and the 150 and 180 .30 Cal have higher...
Corn feeder/baiting is a good way to get them, but hogs can be very nocturnal. I had a lease in TX with a ton of hog sign that my lease partners and myself hunted hard during deer season and never saw a pig during day light hours. Another fun way is to still hunt them in the thick stuff...
Always wondered this, so thought I'd ask the bullet makers... Do bullets get old? I have some old bullets of various manufacture (some I would bet over 30 years old) that I picked up at gun shows every now and then, including some noslers and was wondering if bullets age to the point where...
The chrony is the ultimate truth serum. I have some guns that are "slow" compared to expected results and some that are "fast". I wouldn't loose sleep over a 100 fps or so, but understand your desire to get what you expect out of your rifle. I have a .280 remington 700 Mt Rifle w/ 22" barrel...
