Home Forums Reloading Varmint Rifles H 335 Temp sensitivity

Its just a question of styles...

I have to admit, I either need to start reloading them, and quit wishing they were as cheap still as they were back in Minnesota...

on those rushing the perimeter to close....I bet a 410 would be a fun thing to have for such occasions...I need to pull out that old Savage Model 24 I inherited from my granddad when he passed away back in 1968....

her are various styles. On one PD shoot a buddy and I decided to use rimfire and centerfire handgun and rifle rounds, plus shotguns. They all worked.

Then there's the "start as small as possible so you don't startle the dumb ones" tactic, beginning with sub-sonic .22's and progressing through various .17's, then working up from the .22 centerfires to long-range 6.5's and 7mm's to, eventually, various .30-.50 calibers.

Whatever works.

I gotta say, I love your style.

My personal fave��.

I have tried t get away from it but it just shoots so well in my Ar's with 25-grs and 55-pills. I have shot here at 5500' from 30's to 90's and never had any issues. Since I have 8-lb kegs hopefully I got the ones that behave or at least until TAC shows up again...........

It shoots high when I get to Montana. But just about all powders I have tried do..
I try to give my loads a test in the warmest weather possible.. In th pacific nw. It is somtime hard to find a day over 80 deg. So I load a tad light for Montana.
I also don't give much thought to the most accurate load at 40 or50 degree as at 90 pr 100 it will shoot way dif. I found the 223 with Imr 3031 seems real consistent.. And the 222 is real consistent with data 68.

Popped my cherry doing run-ups the other day, but most of the problem is the FP

O.k, here's one.

Ran my .223 50 gr. btip load out of my bolt gun over the chrono yesterday. The load is 27 gr. h335 cci 450. My chrono told me a five shot average of 3344 fps with a variance of only 10 fps at most between shots, Gun and ammo temp 68 degrees... To be honest I was expecting a little more speed, not that it's a problem. The load shoots tight one hole five shot groops till I wiggle.

My other load with the 50 gr btip is powered by 23gr imr4198 for an average of 3500fps straight up. I was expecting the 335 load to equal the imr4198 load.

Load?
Primers?

6x45 w/85 NPT, 400's. Don't recall the charge, but seemed to top out early anyway. Whatever the charge was, it ran 2685 FPS.

Bolt face needs done....

Boomwack... what twist are you using with that 50gr btip ( 1-9")?

The bolt gun, a ruger MK-II has a 1-12 turn, 22 inch barrel.

I wish it had a 1-9. The heaviest bullet I have ran threw it is the 60 gr. partition and does just fine on deer at 3000 fps and shoots 1 inchers a @100 yards easily.

The h335 50gr. load surprised me with the velocity it gave.

Thanks, I'm working on a good working loads for two .223
I have one a savage 11 and one a CZ 527 Varmint both 1-9"s

Seen another thread on some IMR powders becoming temp insensitive and this H335 is also temp insensitive. So where is the data that lists all of the temp insensitive powder? I have a couple older IMR and JB states those IMR made in Australia are being converted to temp insensitive if I remember what I read. My question is what powders from all powder companies are temp insensitive? Are all Hod temp insensitive? I presume you guys who reload in winder time become mindful of temp sensitivity of powder if you want to shoo loads in the summer?

Val, most of us develop our loads in the summer anyway, blow through them and reload in the winter.
The H EXTREME powder line is supposedly less temp-sensitive. I have used them and been satisfied that a good load will not have scary surprises.
I'd suggest, if you don't know if a powder is "sensitive," then use your best judgment -- stay away from the red line.
I don't use H 335 any more. TAC meters at least as well, and is not nearly as feline or female as 335.

then just to be safe I guess I will hold off on the H335 until summer. I have some TAC that I picked up on the way home from visiting my parents over Christmas break. I have others to try as well.

No one answered my question...is Hornady the only company that produces Extreme temp insensitivity powder? JB mentioned that now IMR has some temp insensitivity powder but they are made in Australia so maybe I can use this as a guide on if IMR is temp insensitive. But all of my Powder is probably 5 years old so I can probably say only Hornady powders are only the temp insensitive powder I have on hand.

I didn't know Hornady produced and sold powder�.

Andy...my 223Rem is a Remington ADL that had barrel replaced with another ADL barrel. And it is a 12" barrel...I thought the ADLs came with 14" but with 12" I'll take a little versatility and see how it goes. For Varget powder what bullets are you using?

That's a new one on me. Have to take a 1 hour drive to Grand Island and see WTF is up.

valad,

Hornady doesn't make any powder, and for that matter neither does Hodgdon. Hodgdon Extreme powders are made in Australia.

Hodgdon also owns the IMR name, and some of the powders they sell under the IMR label are also made in the same plant in Australia and have the same characteristics as the Extreme powders.

There isn't any powder that doesn't react to temperature in some way. Today, however, many powders are more "temperature-resistant" than others, and not just the Hodgdon Extremes but many offered by other companies.
