N160 or N165 for 270win

[Foxyboy43]

6.5 x 55 is a lovely round. I use a 6.5 X 47 lapua a Schultz & Larsen with a gorgeous stock for the summer but my stainless steel Tikka .270 synthetic stock comes out in the winter or for when I need just a bit more oomph.

Actually you could just stick with the 6.5x55 - very little in it either way with the .270 according to those nice people at Sako…..

or N165 as per tim 243 data

Either, depends on bullet weight and there is of course some cross over. Not a huge difference between the two.

Personally I am running N140 with 110gr TTSX and getting 3400 fps, but actually that is too hot.

About to try N150 with 118 grain yew tree copper, should be 3100 fps ish.

N165 is too slow for anything less than 150gr IMO. I've loaded up to 62gr behind a 150gr bullet. 60gr N165 with 150gr gameking gives around 2900 fps in my 22" T3.

N160 would be better for the lighter bullets. Currently loading 61gr N160 behind Barnes 110gr TTSX for a friend.

When I am using 130gr or 140gr bullets in my 7x57 I find RS62 is a good powder (similar to N160). I use 49gr of powder and get about 2,880fps with mild recoil and good accuracy/ballistics out to 900yds. So .270 should be quite similar with that powder.

You're welcome - in fact according to the RS Swiss website, RS62 was specifically developed for .270 Winchester: Reload Swiss RS® - RS62 Rifle Powder

I using N135 with my 110gr .270 TTSX and very happy with the results although they are whistling along at 3298

Gosh - I've never read before of such a fast powder being used in .270, even with light bullets.

Gosh - I've never read before of such a fast powder being used in .270, even with light bullets.

I have exclusively used IMR4350 and IMR4895 for my .243, .270 and .308 loads - the .243 and .270 using 4350. When I cut over to using copper in the .243 I found that the I couldn’t get deer-legal muzzle energy with 4350 so I started trawling around for alternatives and ended up with N135 - I’d also been researching loads for Fox bullets in the .308. A bit of additional digging yielded data for the .270 and a quick ladder test yielded this result (jump set to factory VOR-TX COAL). End of load development (for now)!
