QuickLoad advice - 30-06 with 185gn+


Catch-22

Recommended Posts

Hi,

Could anyone help me out with some QuickLoad advice please?

Load is 30-06 but long throated for 185gn+ bullets, specifically Lapua 185gn D46 and 185gn Scenar, 190gn and 210gn Sierra Matchkings.

I don't know the exact COAL but from case head to start of the throat (per reamer print) would be around 2.822". I guess that puts COAL around the  3.400" mark?!

Barrel: 1-10" twist, 30" finished, standard 0.340 neck (not tight), 

Brass: Lapua 30-06

Primer: likely to be Murom LRP or CCI 200

Pressure: likely to be close to SAMMI max at 60,000psi

Powders: seems H4350 and IMR 4350 is the standard but I'm specifically interested in those available in the UK, namely;

- Viht N150 (maybe too fast), N160, N165

- RS52 (maybe too fast), RS62, RS70

- Ramshot Hunter

In addition to the above, I'd appreciate a 'full list' of possible powders in order to understand how my preferred powders stack up?! 

Many thanks in advance!

That's the powder suggestions (no Hogdons powders etc) for each of the 4 bullets, based on max 60K psi and a 105% fill. Bare in mind the COAL and H2O capacity can affect the results quite a bit. And obviously QL numbers are indicative at best sometimes!

Whilst a staking rifle I’ve used N160 in my 30-06 and whilst a shorter 24in barrel I’ve found it a very good powder but, I predominant shoot 165 grain bullets.

I would be interested to see how your project goes as I was surprised at how the calibre shot at range recently having never tried it before.

@GT3_richy many thanks for all the info buddy - really appreciate the help on this!

@Gandy well I've got a switch barrel rifle; 6.5x47 for more precision work upto 1000m, .338 Norma Mag for 1000m+ and just having a big fat boomer for kicks. I have a couple of spare barrel blanks for each calibre to keep me going.

But i decided to opt for a 3rd barrel in 30-06 as a do all, shoot lots calibre. It sort of has all the good bits a .308w has (easy to tune, lots of components, bullets way cheaper than the long range 6.5mm and 7mm's, barrel life around 4000-5000 rounds, tolerable recoil) but with few/none of the downsides. I know others may disagree, but I've always felt the .308w just struggles to 1000m. Whereas the 30-06 has just a bit more capacity to do so with ease, even with heavier bullets.

According to superior minds, such as German Salazar et al, the key to improving accuracy with the 30-06 is by changing the throat lead angle from 3 degrees to 1.5 degrees. Doing so matches the .308w and seems to really breathe new accuracy potential in the 30-06, which is what I'm specifying on my reamer.

So my aim is to see if by using a long and super fat barrel in 30-06, I'm able to get lots of medium/long range trigger time whilst spreading out my more accurate shooting on the other barrels. I didn't fancy .284w or similar because a barrel would be toast in 1/2 the time. Bullets are pricer too. Didn't want to go .300wm as I've already a bigger boomer than that. Plus 30-06 can be loaded close on the heels of a .300wm. Anyhoo, it's all just a bit of fun. We'll see!?
