Reloader #17 Powder

   Anybody use #17 yet?

I've been working up a load for my 300WSM and using 180gr nosler e-tips (non lead for CA hunting) and mag. primers and 64.5 grs. of #17 powder @ 2.875" COAL. I'm only getting 2930fps and not showing any presure sighs. I think i'll bump up another .5 or 1.0gr I would like to get up over 3000fps, As I was working up the load the hotter it was the tighter the groups were getting. 

Alliant calls for 66.0gr of powder max load for 180gr lead bullet @ 2.860"  and should be 3088fps. Now supposivly if you are using non lead bullets then -2.0gr for max load which would be 64.0gr max.

My nosler and speer reload manuals dont have Reloader#17 data, I called nosler and they said their new book for next year would, but not doing me any good for now.  

Whats you non-lead load data?????

Don't you just love working

Don't you just love working with a new powder that really doesn't have any real load data that is published for it yet?  If it were me I would continue to work it up a half grain at a time from where you are at right now.  Also while at the range take a magnifying glass with you to where you can look at the primers to see if they are starting to crater.  My last loadings for my .340 looked OK to the naked eye but under the glass you could tell that I was close to the point of trouble.  Then I had one case that had a nice shiny part of the rim where it hit the extractor.  The funny part is that all the 10 previous shots had cronied at exactly 3400fps with no variation in the speed.  But after looking at the primers I decided that I better back off a little.

I'm not a fan of judging

I'm not a fan of judging pressure by primer's. Problem is it could be soft primer cups or even a fireing pin hole a bit to big. But a really flattened primer will get my attention every time. I do like to watch for ejector marks on the rim and case head expansion. Also a hard bolt lift is a gimme! I'd also go up .5 grs at a time. You may or may not get a published velocity with your rifle, no big thing. A 180gr bullet at 2900 fps is nothing to sneer at!

#17

   Thank guys

     When I was at the range I was shooting 5 shot groups and checking for a tight bolt lever with each shot and inspecting for ejector marks on the cases and every thing looked and felt good. I loaded up some more round this time 6, and am going to do two 3-shot groups, I bumped up in.5 grain increment. If I can just get sub 1" group at one hundred yards and around 3000fps i'll be happy. They claim this powder is faster made for extreme weather and not to vary with its pressure's. It was 41 deg. and foggy out side when I cronied it, I'll be testing it again when its 110 deg. and dry. Heck it was neer 0 deg. last nov. in Colorado durring 3rd season.  I'll post some new results in a few days.

Alright it was sunny and

Alright it was sunny and 55deg. out today so I did a little shooting.

Tikka 300wsm, 180gr Nosler E-tip, Win mag primer, Reloader #17, COAL 2.875"

64.5gr = 2935fps = 1  7/16" group 

65.0gr = 2961fps = 1  1/2" group 

65.5gr = 3003fps = 1  3/16" group

66.0gr = 3040fps = 1  1/4" group

66.5gr = 3059fps = 1  1/8" group

Conclusion: E-tips suck or just California's Laws.

I thought maybe it was the Leadslead i was using, cause I cant shoot from my shoulder now so:

I shot my Nosler 180gr Accubonds, 66.5gr = 3030fps = 11/16" group, Now that what im talking about!

elk load damage

No,... not for the 7 mag just my.338 win mag. I'm currently running #22 in the recipe for the 7mm. I had devoloped a load for her using the 162 gr. Hornady BTSP on top of 68.8 grains of RL#22 for my elk loads and reduce it down to 65.5 grains for whitetails while hunting here in Michigan with the same projectile. I had the misfortune 2 seasons ago to load up the 7 mag with one of my elk loads by mistake and boy did it ever put a hole in that poor deer. I'm sure she didn't feel a thing and when I hit her I was shooting uphill. It entered right where it should behind the shoulder and exited on  the opposing side just below the backstraps. I had my elk loads on one side of a 50 round box and the deer loads on the other and so labled but I took 3 of the wrong ones. I'll try to attach a picture below of the exit damage on her after skinning her out.

rl 17

I'm using it in a 250AI and a 270 with lead and non-lead bullets.  Seems to shoot well in both.
