Hi folks,

Looking at loading up some 60 gr Nosler Partitions or some 65gr Sierra Gameking SBTs.

Going to start using Ramshot TAC. Anyone have any other suggestions?

Plan on using for Muntjac, Chinese Water Deer and the occasional fox.

Scrummy

that'll work just fine.
I use AA-2230 and H-322 so really no different than what you got there.

I agree with Lamar. I had a can of Tac and the loads were as good as H335 and Bl-C(2). My rifle shoots less than a minute but doesn't shoot bug holes; it is a standard 700 tupperware stock rifle that I bedded myself. I use it mostly for shooting offhand and shooting sitting with a sling, so it might shoot better if I focused on load dev, but any spherical powder with a published max load seems to shoot well.

Viht 133/135/140 as we can get in over here readily enough.

Do you find so? I don't find the Ramshot stuff so bad.

I find data for Viht tough to get though I like the powder.

Hello Scrummy

l've got piles of the stuff up 'ere Sir.

l pick it up in the westmidlands without a problem when l'm down the workshop (Brock & Norris) l'm also toying with several Lovex powders imported by Westlander, which are some of the old Accurate Arms powders. My stocks of IMR and Hodgdon's are dwindling.

Having developed loads for a lot of rifles, when l worked with Mike for two years l've come to like Viht a lot, especially their single based powders.

l've also found Sako factory loadings to be very consistent and they use Viht, of which l have their old file and load weights for their factory rounds.

Regards.

Ratty.

Hi Ratty, getting the powder isn't a problem, it's more the data for it I find a challenge.

Scrummy

Ah, righty....

l'll have a rummage about in my library and also have Q/Load here, so if you'd give me your components and barrel length l'll crunch some numbers for you.

tac and h335 are excellent choices

Very kind of you!

.223 Rem, 1:9 Twist, 22" barrel, Nosler Partition 60gr and Sierra SBT 65gr

Ok, so allowing a decent margin for safety, 300bar below P-Max, as l don't know what brand of brass you're using, or the throat dimensions.
Some of these loadings exceed 100% case fill, but with a drop tube you're still within capability.
Sierra 65grn SPBT OAL - 2.260"
Nosler 60grn Part' OAL - 2.260"

Ramshot TAC - 24.5grn. Sierra SPBT 65grn - 2825ft/sec. 1152ft/lb 89.92% burn efficient. 24.9% ballistic efficient. (3340bar)

Viht N133 - 22grn, Sierra SPBT 65grn - 2841ft/sec. 1165ft/lb 99.73% burn efficient. 30.5% ballstic efficient. (3425bar)

Viht N135 - 23grn, Sierra SPBT 65grn - 2830ft/sec. 1156ft/lb. 99.135 BURN EFFICIENT. 29.3% ballistic efficient (@ only 107% fill and only 3088bar - P-Max is 3792.12bar)

Viht N140 - 24grn, Sierra SPBT 65grn - 2906ft/sec. 1219ft/lb. 98.71% burn efficient. 28.6% ballistic efficient (3503bar)

Ramshot TAC - 25.5grn Nosler 60grn Part' - 2960ft/sec 1167ft/lb. 89.42%burn efficient. 24.2% ballistic efficient (3484bar)

Viht N133 - 22.5grn. Nosler 60grn Part' - 2933ft/sec. 1146ft/lb. 99.32% burn efficient. 29.4% ballistic efficient (3362bar)

Viht N135 - 23.5grn. Nosler 60grn Part' - 2911ft/sec. 1129ft/lb. 98.4% burn efficient. 28% ballistic efficient. (3000bar)

Viht N140 - 24.5grn. Nosler 60grn Part' - 2989ft/sec. 1190ft/lb. 97.91% burn efficient. 27.3% ballistic efficient. (3411bar)

l would (as always) advise starting 2 grains below these loadings and work up, watching for any adverse pressure signs.

l hope some of this helps.

Ratty, that is awesome and thank you!

Had a play with the Sierras over TAC today. Encouraging start, need to play with seating depth a bit more - Shot well up against the lands but not quite found the second node yet. Ran out of range time.

You're more then welcome.

l tend to load a given powder load (within 5% or less of maximum, or where l want the velocity) and then tinker with the seating depth first. l've found it works for me.
Best of luck with the loads... So many itches, and so little time to scratch.

I used it for about 2 years in my IBS Varmint Hunter Class rifle in 6PPC. It performed very well but, the burn speed varied greatly from lot to lot and, it was very dirty.

Hello Doc'

Yes, those have been my issues with TAC and some other Ball powders.
We don't tend to get massive temperature swings here, yet they are still enough to give variable velocities and pressures. Hence why l tend to use Viht whenever l can. lt's not helped us over the pond since the new "REACH" compliance regulations came into place this year, which means that when a lot of the US/ADI powders are used up there'll be no more, until either they're reconfigured or no longer imported.
What's wrong with a few nasty chemicals here and there.

Ratwhiskers,
It is interesting to see someone loading TAC and N133 as I have done with my .405 WCF DG loads. At first was was in my Winchester 1895 .405 with Woodleigh 400 grain .411 bullets.

TAC - best performance was with near max loads and using Federal match Magnum primers. The final shots with Chrony showed a net average deviation of zero with a highest single shot deviation of one (1) FPS. Also a very accurate load at 48,000 + psi. Very clean burn too.

N133 - not quite so clean(strange odor at low pressure) or fast as TAC UNTIL I changed to Fed Match Magnum primers and then equal velocity with much less pressure with no peaks! In fact, the VV N133 pressure for 400 grain bullets is so low (less than 40,000 psi, that I can use it in my Simson Suhl .405 DR and achieve regulation.

Both powders are very good, but for my applications N133 is better suited due to lower peak pressure.

PS all the .405 loads were compressed using a 24 inch drop tube.

I noticed something else with these two powders. Wondered if something in the N130-N140 couldn't successfully be used for heavier .223 Rem loadings and 250gr Accubonds in 9.3x62...

Hello again old man.

Viht's own book states

250grn Nosler Accubond
N530 46.1 @ 2224ft/sec - 51.2 @ 2444ft/sec
N140 52 @ 2274ft/sec - 57.6grains @ 2493ft/sec
N540 53.4 @ 2300ft/sec - 61.4 @ 2605ft/sec.

Nosler Book 7
Barrel Length 26"
250grn Accubond
N135 49.5 @ 2326ft/sec (Most accurate load)
N135 51.5 @ 2429ft/sec
N135 53.5 @ 2487ft/sec

l hope this helps.

Ratty.

Cheers Ratty!

N140 might be the way to go if then.

Scrummy

Yes, and a degree less pressure than the N5 series of powders.
l've got some bits n spare bullets coming by way of a friend and there's a nice 338-06 in a sale section... Just one more of those itches....
Best of luck making some decent sized holes.

Is that on the "SD" per chance? Nice looking rig and be great on the piggies

Hmm... Maybe....

l've got a T3 action here with a shot out barrel, l may just have to look at options down the line. lt's a great cartridge for anything from mouse to moose...
l nearly had a 9.3x62 on ticket up here for deer. Slowed down and using soft bullets it would have made for a nice Red to Roe rifle.

I have a 9.3x62 rifle. Mainly for boar. Does a good job on roe as slow.
