Gotta love internet experts.

208gr amax!!!!

But ebf shooting ftr which only allows max 155.

Um, ok then

VC, I use 155gr Lapua Scenars out to 1000yds, they seem to kill paper targets just fine...

Niblet, I think the 155gr restriction on FTR has either already been lifted or is about to disappear. I get the Scenars at a very good price, so will probably keep shooting them. The twist in the Omark is also 1:14, which limits how heavy I can go.

Keen to hear Norway's answer, like I said, I might be missing something, but the question is genuine.

Also 100gr - 120gr projectiles are light weight in a 6.5mm for long range

The Vid is targeted, I thought at extending the range one can ethicly take game, I could be wrong?

Ebf would you not use a ballisticly superior game proven projectile for game?

The DVD is about fundamentals (position, trajectory confirmation, wind calling, valley shooting and inclines) of long range shooting, they shoot paper, gongs and rocks (no animals). Have you watched it ?

Game bullet for game, doh - of course, but what does that have to do with my initial question ?

It's kinda like asking if you would use a game projectile for target or gong shooting if a much better non-game option exists...

Yes I have watched it.

Not being a competitive target shooter confined by rules I say use the best tool for the job Ie the highest bc projectile that will still provide terminal performance.
And in the case of 308 win lr hunting with 150gr is being a dick.

Is that better?

18 (0.1mil clicks) = 1.8 milrad = +/- 6 MOA

I've had a look at my windage tables and to need 6 MOA windage adjustment at 900yds (closest I have to 800m) the wind would need to be 8 mph or about 3.5 m/s.

So not sure what projectile you were using for 308, but that does not match the windage data I am using to shoot long range competitions (155gr Scenar @ 3020 fps).

Also ran some tests on JBM Ballistics for (using wikipedia speeds )

.308 155 Amax @ 910 m/s for full value 2m/s wind = 11 clicks @ 800m
.308 155 SMK @ 910 m/s for full value 2m/s wind = 10 clicks @ 800m

.264 100 Amax @ 970 m/s for full value 2m/s wind = 11 clicks @ 800m
.264 120 SMK @ 860 m/s for full value 2m/s wind = 13 clicks @ 800m

Maybe I am missing something obvious, but can't see the massive difference between the 2 calibers...

All i took from that section was that info.was givem as examples to help with developing rules of thumb for your load. Mines looking like range-3 to around 8-900. Run your figures for.your projectile through your programme. Write them.down fpr the ranges and observe the pattern. The percentage of value for wind angle will transfer across whatever your rule eventuates to.

So I guess you don't want some Berger 155gr VLD Hunting pills then

What if you had a 1:13 twist barrel on your hunting rifle ? Would you still insist on a heavier projectile ?

I want to know what sort of paper he printed onto fpr his turrets. Like the idea of the turrets set to ranges and used in cpnjunction with the card he had. No electrics to go flat on extended trips into the hills

They also.state quite clearly in the dvd at the end they have been dealing with practical long range shooting technique. Discussion of appropriate projectile and projectile performance is a whole nother subject to.potentially be looked at in another dvd.

Yes DS, all I am asking is what the actual data is that sits behind the rule-of-thumb he mentions for windage on 6.5x55 vs 308. No matter what I enter into a ballistics calc, I cannot get a similar picture... It also does not match the real-world data I have collected while logging wind corrections doing target shooting at longer ranges.

This showed how to do it in excel kind of...... https://www.youtube.com/watch?v=igmIslhusgs

Yeah but its the type of sticker paper to use that will be waterproof

I think the answer to your question is that the range card for the 308 was worked out with V0 at 755 m/s...

Great dvd Norway, congratulations on what is a clear, concise introduction to LR shooting.

Reminds me that I need to get out and practice more often with my 6.5 rather than rely on high bc out of a big magnum. Time for a load up for the wee 6.5 I think
