LOVEX S070-05 or SW4350 in the 3006 (2025)

You need to state your chambering.

Comprehensive data here, as any web search should show: https://explosia.cz/app/uploads/2016/11/reloading_Lovex_EN.pdf

I'm not sure what S070-05 is. The only Iovex powder that I know with a suffix is the double-base D073 range, that comes in D073.4, .5 and .6. S070 is just, well S070 (single base). So what is it that you have ?

FWIW I have used S060 for full power loads in a number of chamberings, as well as reduced loads with cast lead, with good results. Not that that is relevant.

Explosia powders are good stuff. You might even be familiar with them re-branded for the US as "Accurate". powders.

OK, a Google. Which is easily done.

Shooters World seem to simply rebrand Lovex powders for the US market. And make no bones about it.

So use the Lovex data to which I referred earlier.

SW4350 is Lovex D070.

Quote: And cut to the crap.

RIFLE POWDERS
SW4350
SW4350 is the slowest of all the
4350 derivatives. As such, it has
broad capabilities in moderate
calibers where other 4350
derivatives cannot reach 100%
loading density. It also has
enhanced capabilities in larger
magnum calibers, where other
4350 derivatives cannot reach.
If you seek accuracy, one of the
keys is to find a propellant that can “fill the case and seek maximum velocity”.
Several shooters have found this relationship to be true with SW4350, and are
impressed with its performance. But please understand, SW4350 is not exactly
the same propellant as H4350. Ranked in fastest to slowest of the 4350 derivatives: H4350, IMR4350, Accurate 4350, SW4350.
SW4350 has tremendous capabilities across virtually all long-range class and
magnum class centerfire rifle ammunition.
Despite SW4350 being an extruded propellant, we have found good flow characteristics through a volumetric powder dump. The grain is narrow, and cut short.
While some reloaders insist on weighing each powder charge, we did not find
that extra time necessary when loading for accuracy with this propellant.
Another advantage to Shooters World propellants is the long track record of
these propellants. Our manufacturer has been making propellants since 1920.
In addition to Shooters World reload data directly accessible from our home
page, many of our propellants are sold throughout Europe under the Lovex
brand. The Lovex published reloading manual is available on-line, and also
linked directly from the www.shootersworldpowders.com website home page.
There, you can find additional data for such calibers as 7mm Remington Magnum, .243 Winchester, .270 Winchester, 6.5x55 Swedish, 8mm Mauser, and
even .338 Lapua Magnum.
The density of SW4350 is approximately 0.9 grams/cc. It contains a level of
flash suppressant. Its extruded geometry is of a narrow diameter, and cut short.
Therefore, its drop consistency through a volumetric charger is quite consistent
for an extruded propellant.
Under the Lovex brand, this propellant is referred to as S070.

No, SW4350 is Lovex SO-70 which used to be sold here until around 20 years ago as Accurate Arms-4350 and has been available since then under the Lovex name. It is a single-based tubular powder. I don't think there is a DO70, but if there were it would be double-based.

AAC-4350/SO-70 is the slowest of the 4350s, so is far from being a close substitute for either IMR or H4350. It should suit the 30-06 well as the case has enough room for it. The current bottle I have under the SO-70 name which I bought last year is considerably slower and/or lower energy than the 4350s and I couldn't get enough in the case to give full velocities in 7mm-08 with a 160gn Sierra being well down on other 4350 alternatives. If Shooters World's stocks are the same, it'll behave more like the 4831s than 4350s - but no problem in the 30-06.

Use either SW's or Explosia's loads data. Both sets of tables are on the Shooters World website either as straight-in table or IIRC for the Czech data via a link.

Oops, I said D rather than S. My typo. I still regard the Explosia offerings with affection. And the Westlander chap who gets them in, also.

Thanks for engaging, Laurie and putting me straight.

I'm very fond too of the Lovex powders @Sharpie, especially the extruded single-based SO varieties. Between Covid lockdowns I ran a series of range tests last year using some 16 powders in a 7mm-08 F-Class rifle looking at alternatives to the now banned H414 and H4350. I'm just about to write this up in Target Shooter online magazine.

My (and Hodgdon's) top charge of H4350, 45.0gn gave a 160gn Sierra TMK 2,784 fps (31-inch barrel) and a one-hole 3-shot 100-yard group, so that speed became the benchmark. In practice, it was easily achieved by nearly everything tried, and frequently bettered with the best (in speed terms) almost hitting 2,900 fps at reloading manual listed charges.

SO-65 acquitted itself very well, as I expected. Explosia shows it as far too fast burning in its burn rate chart - it is closer to the 4350s than H. VarGet. SO-70 was one of the last pair I tested just before Christmas and Lockdown-3 and I initially wondered if I'd picked up the wrong powder bottle and loaded the extremely 'slow' SO-71 by mistake such were the very low MVs and their discrepancy from QuickLOAD projections. I loaded yet more up to the old Accurate Arms Co. manual's 46.0gn maximum, as much as a Lapua 7-08 case holds, and got another range session in, just! Results were good in some respects with some very small groups and ES values, but MVs only hit 2,690 fps with the 46gn top charge, 90 fps down on H4350 and the lowest MV produced by any contender.

So, I don't know what to make of SO-70 right now. It may be that I have a bottle from an abnormally 'slow' production lot. If the norm, it's certainly very limiting to its use in smaller case cartridges that use '4350-equivalent' powders like the Creedmoors, 243 Win, 260 Rem etc, but not an issue for those with more room like 7X57mm, 270 Win and 30-06. Even so, people won't get full MVs without exceeding liswted maximum loads and need a chronograph to do their work-ups. Or, it may be that the mild Russian primer I was using wasn't aggressive enough to counter the chilly temperatures of the test session.

I shoot a lot of Shooter's World powders. SW4350 will be fine in the 30-06. I have used it in 6.5 Creedmoor and 300 Win Mag. Excellent performance.~Muir

I originally bought this powder for my 6.5 Creedmoor and 140 gr bullets . However , I am using 120gr (Speer Gold Dots) bullets with N203b and am having good performance. Will know if the Gold Dots are suitable for Pigs this fall.
