H4350 Temp. Data

Does anyone have any experience with temperatures affecting this powder. I know Hodgdon says it does not. Just wondering if anyone has any first hand experience. Thanks

Re: H4350 Temp. Data

I think the only way to prove or disprove it, would be to put some powder into a heated container. Then, at the range you could fire ammo with powder at ambient temps(let's say ~40deg), and load(locally) hot powder ammo(let's say at 100deg) and shoot side by side across the same chrono setup/condition.
With this, you would have the same conditions except different powder temps, to compare.

I don't know if anyone has ever done this..

Re: H4350 Temp. Data

They LIE!

I use it to compete with at 1K and granted my loads are on the upper limit but the ammunition used at 55 during the first relay must be reduced by .5 at 85 in the afternoon. The ambient also has the action and chamber warmer to start with but without going into finite detail it does change the pressure.

Re: H4350 Temp. Data

I have had some minor issues as well here in Colorado. When it was high 80's - low 90's, the ES was going crazy with 52-63 FPS. In the 70's it was better at ES of 29's but still high. This is with 4 different rifles; they are over the counter rifles.

No matter how exacting on everything, I cannot get a very minimal ES with H4831sc, H4350, and even H1000. I switched to IMR 4350 and the ES went back to mid teens and group closed back to 1/2" @ 100.

There must be something good about the powder but I have decided to not be a kool-aid partaker.

Re: H4350 Temp. Data

Thanks for your input. Does anyone have any experience with difference with cold. Since it will mostly be used this fall in Kansas and Nebraska. 338 have you had any difference in the 20 to 30 degree range?

Re: H4350 Temp. Data

The first 3 days of Colorado 3rd season las year was in low 70s. The next 5 days was 20s in the mornings and 50s thereafter. Unfortuantely I was actually using RL19 in my 338 last fall and honestly never got a shot off so I can not attest to RL19 performance in that cold temperature nor the H's performance.

For what it is worth, I am reloading hunting party's custom 300 Win Mag with H1000 but 2 for a 30-06 and a 7mm Rem Mag I am going with IMR 4350 and IMR 4831 respectively. For my 338 Win Mag I am not sure but chances are not with the H powders.

Let us know your approach.

Re: H4350 Temp. Data

I have had totally different experiences with H4350. I have shot it in 243AI's 6.5x47L and had really tight ES's, like in the 6-7 range. I have chronographed loads I have worked up in the 6.5x47 when it was 20ish degrees outside and have only noticed about 10fps difference at 85 degrees. Most people I talk to say that 4350 is probably the most consistant powder in the Hodgdon line. From what I have seen so far, I would have to agree.
