RS62 Burn Rate
- Thread starter NigelM
- Start date
Because it give 35% more down range energy delivery and cuts wind drift by 30% over the Norma 130 soft points he has been using.
Good enough reason in my book and makes a good chambering a great chambering.

Haha at what range are you talking? Bet inside 400 yards it’s a wash between the two.
Over thinking it perhaps??
out to 1000 yds target
energy inside 400 yds is major reason to step up in bullet weight class
but mainly because I wanted to

That is at 400m. He's trying to do a bit of LR playing with it too so wanted a bullet that would hunt and hit paper at range.
Not over thinking it at all, just making a significant improvement.

If you want to make an improvement keep the 270 for deer & buy a 6.5 creedmoor for range work.
I highly dowt your barrel will even stabilise that 145 ELD at range. At 100 yards it may well do but at 600 yards I would highly dowt it.
You would be shocked how efficient a 130gr bullet would be at range! That being said I don’t know one single person who shoot a 270 for target lol
Let's keep this on topic shall we...

I am. Just pointing you in the right direction! You planning on using factory ammo too??

No deer or fox will be able to tell the difference in a few Ft lbs more energy.. Fact!!
Complete waste of time! Sorry you’ve gotta laugh.
Going through all this time, money & fuss wen with a smaller but more efficient calibre you will achieve the same goals..
Leave the 270 for deer use only yea

Only your making it out to be that. Prob because deep down you know it’s the right choice

I have two 6.5x47 Lapua's already. More accurate and more efficient than the Creedmoor. But if you have no imagination and just want to follow the latest fad that's your call. I'm not criticising it.

I highly dowt that. My creedmoore has much better ballistic than your 47 lapua Plus has more case capacity so can push them heavier bullet at greater speeds!
6.5x47 only shines when your running it at max pressure lol
I wish I had read your extensive research on energy transfer and terminal effect before I had wasted all my time and money on reloading heavier bullets for one of the rifles I already have....
Perhaps I should sell them all and just get a Creedmore.....

Why exactly do you feel the need to hijack this interesting thread with your nonsense @Slickshot?
The 145gr ELD-X is a very popular and effective choice in .270 Win. My mate Danny has been using it to great effect on 500m deer in windy high country conditions, I shall dig out the thread link from our NZ forum if you wish. Complete with nice landscapes, sweaty deer hunters and terminal ballistic / wounding photos of dead deer.
Its also very popular in .270WSM.
You'd be chewed up and spat out if you pitched up on our forum spouting this kind of cobblers.

It’s a forum to voice views. Funny thing is when I voice my little girls like you say it’s “hijacking” lol
It may well be in your world “popular” but in my world we use 130gr bullets & no deer ever complain. I feel the 145-150gr bullets is pointless. You wanna shoot heavy rounds on deer at range I personally would get in the the magnums.
That being said a 270 shooting a 130gr Accu-Bond @ 3100 FPS would take any deer at your given range.
Anyways this is getter boring. One day you’ll see the light
So... let me me try and understand your train of thought. You said in #55 "High BC bullets is what you want not “heavy", Lol".
Hilarious, clearly.
The 130gr ABLR has a quoted G1 BC of 0.435.
The 145gr ELD-X has a quoted G1 BC of 0.536.
Hmmm.
I dropped my mate Danny a line, I said hey Danny how fast are you pushing those 145s? Awww, 3130fps thereabouts Dave.
So lets look at the difference here. Danny's using RL26, Nigel is using RS62. Let's assume both rifles are zeroed at 200yds.
At 300yds in a 10mph crosswind, the numbers are:
Danny: path to line of sight -5.2", windage -4.6"
Nigel: path to line of sight -6.0", windage -5.0"
@Slickshot's magical 130gr Accubond at 3100fps: path to line of sight -6.2", windage -5.8"
Hmmm, I say, in my best Yoda voice.
As a hunting round, would you like to know how much more energy the 145gr ELD-X has over the 130gr Accubond? Nigel's is +6% and Danny's is +19%. Ouch.
In post #46, you make some claims about stability and the shocking capabilities of both a .277 and a 6.5mm 130gr bullet at range. Let's look at that for a moment, at 600yds.
Nigel's 270 & 145gr ELD-X @ 2900fps: path to line of sight -66.6", windage -22"
Random 6.5 CM & 130gr ELD-M @ 2950fps: path to line of sight -64.1", windage -21.2"
@Slickshot's magical 130gr Accubond at 3100fps: path to line of sight -63", windage -26.2"
Oh. I'm not shocked. Actually, what was it I was supposed to be shocked about?
By the way, Danny's faster ELD-X poops on the Creedmoor numbers... -56.7" and -20.1". Splat!
Regarding stability. The Miller value for the 145gr ELD-X in a standard .270 Winchester 1:10" twist barrel is between 1.561 - 1.596 depending on velocity. This exceeds MilSpec stability requirements for long range shooting by up to 0.1. I'm not going to assume you know the difference between gyroscopic stability and dynamic stability, as nothing you've posted so far is credible, suffice to say that as long as a bullet starts with gyroscopic stability (Sg), it will maintain stability as Sg decays a lot slower than velocity. However some bullets are affected by a significant loss of dynamic stability (Sd) as velocity drops into transonic speeds, around 1300fps. Considering this equates to a range of 1150yds, I'd say that he hasn't got too much to worry about, if it happens at all.
So now I've finished being a little girl, hopefully your deeply buried inner good-bloke will be allowed to surface, and he'll agree he really must stop chickening out and allowing peckerhead to run the show.
As a final comment, I would like to point out to one of our other contributors that the above is a good example of why Quickload is so useful. It allows data driven analysis and informed decisions, rather than plucking nonsense from the dark recesses of our rear ends.

Dodgy you are on fire this morning!
I was trying to be polite but I think your slightly more direct approach is likely to be a bit more effective.
