"Cool" powder for the .17 Remington
Hey Guys
Time for me to put a new tube on my .17 Remington. Seems that I enjoy wearing out barrels in that caliber. Even though I do not usually load hot I have been using mostly Varget, usually around 23-23.5 grains, with 20 and 25 grain bullets. A very knowledgeable friend says that powder burns too hot and advised me to use a cooler powder so I can get longer barrel life next time. OK fine. So I guess I need to know what is the coolest powder that I can use and still get the speeds and accuracy I want? Anyone got a clue here? As always, all reply's are appreciated. |

I'm not sure if I can comment on the "cool" factor but I like 8208xbr better than Varget. ( I don't own a 17 rem)
Another method would be maybe running a slower powder at a lower pressure to help combat throat erosion? Ramshot Big Game would be a thought. I have this in my 17 rem notes for BG "I ran 28.0 grains with 20's and 26.5 with 25's" again I do not own nor have owned a 17 rem. but it has peaked my interest several times.

Don't know about the "COOL" factor, but I know some that use CFE 223 running around 4000-4100 with 25 grain bullets and are quite happy. Bill K

BLC2 is a little slower,I like it for 20 gr bullets. I used to run W760 with 25's it is slower then BlC2. Now I run H414 with 29,30's, I think that is as slow a burn I have tried. Shot probably 1500 rounds with the W760(high book load)and 25's before new barrel time.

I think 2006, I was using w760 in the 80's. Haven't purchased any since 2001-2. I still have some, but I wouldn't substitute with out load workup.

Yes, I believe W760 and H414 are the same powder. AA2700 is a similar speed, but not the same powder. I have used a bunch of W748, and W760 in my 17 Rem. I have some development loads of AA2700 and IMR 4320, but haven't gotten to shoot them yet. Many folks also like IMR 4198, but I usually stick with ball powders or very short stick powders.

If you want to keep your barrel cool, burning less powder works quite well. One of my favorite light loads for the 17 Remington is 17.0 H4227 pushing the 20 gr. Vmax bullet at 3700 fps. Chunks critters out to 200+ yards, the barrel stays cool, and delivers outstanding accuracy in my rifle.

Johnly, I would have never thought to use something as fast burning as 4227... But my gut thinks something like that is the only way to reduce heat. Less powder.
TinMan, 4320 is what I cut my 17 caliber teeth on. I got so frustrated trying to get it in the neck... but once I did, it shot very well. However this is what drove me to start shooting ramshot big game. What I didntvlike was you about needed a compressed load and eventually went with Tac which does the same thing with less powder (less heat). That said it’s not a cool powder, it seems to warm up first about 8”-10” up the barrel from the chamber IIRC. I was always going to build a 17 Rem Imp because I thought it might be a better capacity case for BG. I also bought 8 lbs of 2700 to try out in the 17 Rem but never got around to iplay with it much yet. I also use Tac in the 27-222 and I think the 17 Jav Imp. And Tac really shines in both of those cartridges but I wouldn’t consider them cool barrel , just less heat than the 17 rem I prefer the ramshot powders but the only way I have learned to keep the barrel cool is shoot several guns and switch off often.

I want to say there are 3 powder "bases" single, double and triple. each creates more heat from what I recall.
Powder quantity also doesn't paint the whole picture. for example in 9mm Titegroup is a popular power. It uses close to a 1/3 less power than most other powders yet it generates some of the most heat from a 9mm load. It however is a triple base powder. |
