Home Forums Hunting & Shooting Ask The Gunwriters New IMR powders for sale from Hodgdon

Listen you blokes, leave the new stuff alone and keep burning through the Extreme line.

If demand for it drops there, they'll start making less of it here and all I can see that doing is driving prices higher than the FIFTY FIVE DOLLARS per 500 grams I am paying now!!!

Bingo. I do not chase RCH's. Any appropriate powder will get me withing 50 fps of optimum. That said, some folks do have to make a living on such "news", that I do understand.

The downside of Australia that is so unknown to the outside.....Aussies get stolen from every time they buy anything.
I filled up last night @ $2.87 a gallon or about half what Aussie's pay and they have their own oil from Bass Strait. The Oz Govt will never disclose what it costs per barrel to extract. The Greiner 3+3 tax per litre (That is $0.03 per litre for 3 years to fund roadworks) added in 1987 was never lifted, they just stopped advertising the tax.

The Aussie designed and made Holden Monaro was imported to the US and sold as the Pontiac GTO. I saw them for as little as $26,000 new where by Aussies paid 2-3 times that for the same car and that is just 2 examples of thousands.

Cold beer and sunshine ain't everything.

Indeed John.

I used to think decoppering agents in powder was just a farce or a new marketing tactic etc.

I found out I was wrong, some powders with decoppering agents work and work amazingly well.

Recently I was doing load development on a new 6ppc barrel, I used the same cases,primers, bullets on all loads so the only difference was the powder. I used the tried and true VVN133,the new Accurate LT-32 and IMR8208XBR.

To make a long story short VVN133 and Accurate LT-32 would leave a trace of copper with a single shot down the barrel and with as many as 30 shots down the barrel the IMR8208XBR left absolutely zero copper !!!!!! amazing

N133 has been around forever but it makes me wonder why Accurate did not use a decoppering agent in the LT-32

Probably because LT-32 was primarily intended for benchrest shooting, and benchrest shooters are going to scrub the hell out of their bores after every few shots anyway!

Are there current available powders with a de-coppering agent suitable for the 300 win mag w/165 and 180 grain bullets?
I've got a barrel that's a terrible fouler. It doesn't get used much because of that.

The new IMR powders that started this thread are supposedly available right now. 4451 and 7977 would be the two to try in the .300.

Or you could also install Dyna Bore Coat.

This one would be a good candidate for DBC, I'll try that first as I'm in the process of super cleaning the bore right now.

Yeah, super clean bore is key to successful DBC application.

I think some of the DBC "failures" we read about are from not fully cleaning the bore, pre-application.

I'm biased towards the Hawkeye to check it out. A clean patch doesn't necessarily tell the whole story.

Up again.

It's been a while since I've seen the list, but I believe it includes 748 and maybe some of the others, perhaps H335.

The problem with many older spherical powders is they burn (or burned) so dirty the resulting powder fouling (which is pretty abrasive) tended to negate the value of the decoppering agent. While newer versions of those older powders tend to burn somewhat cleaner, decoppering agents are most effective in cleaner-burning powders. There are also some other extruded powders that supposedly contain decoppering agents, I believe some of the Reloder series, but I've never seen much reduction in copper-fouling when using them--and as with many other things such as primers and bullets, companies will vary the formula from year to year. Probably the best thing to do is ask powder companies themselves for the latest info.

Considering the total lack of Ramshot Big Game, will any of these new powders work their magic in the 9.3x62?

I called Alliant Powder Co and they said they did not have any de-coppering agent in their powders. I talked to a guy that I think answered the phone after I had to go through a contract service co to get to him.

I'd guess 4416 would work with both 250's and 286's, since it's in the same approximate burn-rate range as Varget and RL-15. 4451 might be about right for 286's, but Hodgdon doesn't have them listed on their data for the 9.3x62 yet.

The problem I had calling them once before was they didn't want to acknowledge that the round can be safely loaded to modern pressures.

You're going to find that with older classic rounds, like 6.5x55, 7x57, etc.

Some providers will give loads for modern actions, some stick to vintage gun limits.

I like to research on line for that type data. Load Data is a good source, but you have to subscribe. To me, it's a good deal, as they have most proprietary loading manual data and you won't have to buy a stack of those to have the info.

Good to know. I'll be doing some 4166/8x57 loading over the winter.

FYI, Lohman arms claims to have all 3 in stock. Graf's and powder valley have 4166.

Saw all of those at the LGS yesterday, 29.00 a pound. Saw something else, Hodgdon killed off the IMR 800X. Its now Hodgdon HI-Skor 800X. Whats up with that?

Was limited to 2 lbs per day, picked these up yesterday, going back today for 2 more.
