does 1680 perform that much better than 296 in the max?

[Deerhunter#1]

well still waiting for accurate to start shipping this powder as they told me last week they just got it in and would be packageing and starting to ship out to dealers. I have been shooting 22 grains w296 and 180 hor ssp bullets(MAX DATA CALLS FOR 21 G SO USE AT YOUR OWN RISK). That said accuracy has been decent at 100 yards but not the greatest. Have seen several post here where people are saying there gun shoots that powder better than any and really havent seen anyone really jumping on with 296. Is that realy the best powder to use in the handi max as far as you guys feel?

[OSOK]

I haven't been able to locate 1680 in my area, so I have been using H110. I hae had very good results, accuracy running an inch or slightly under at 100 yards with the same bullet. I use 21 gr. (max load in the books).

[gendoc]

to some it is............but to me, for my kinda accuracy with my seasoned handloads...  neither is used !

[cudatruck]

ok Doc, I'll bite... what cha' usin'?

[Doublebass73]

I can't find 1680 in my area either.

Has anyone had any luck with Lil' Gun and the 180 SSP's?

ok Doc, I'll bite... what cha' usin'?

Good to know, I'll try it out before I spring for a can of 1680.

Can't speak for all but A1680 shines in my rifle.  Have tried 2400 and 4227 and just couldn't get the accuracy shooting RD359175 and RD359190 both GC and paper patched.  I do use what some consider stiff loads that I won't post in open forum, but I'm able to seat out somewhat and have no signs of pressure at all plus no leading of the bore.  Goat

I love 1680 with jacketed bullets.  (Shoots the ssp's about the same) Have had good results with lil gun with cast.

A1680 is Steve's powder of choice for more than one of his Maxis, per my email confirmation with Johan Loubser of Accurate Powder, being a bit too slow for the cartridge even compressed to a load density of 120%, although at pressures beyond the SAAMI MAP of 40kpsi, would require an SB2 frame, not for use on an SB1, but his pressure tested loads listed at the COL length specified are all under 40kpsi and safe on an SB1.

[revbc]

Duane, it is.  That is a hornady xtp 180gr

I picked up a brandy-new can of AA1680 yesterday at my favorite locally owned and operated one-horse gunshop.  I figure if this shop has this powder then the big boys ought to have it as well.  He only had one can and I asked him if he sold the rest and he said "no" and that he hadn't ordered any it was shipped to him by mistake.  Good thing I got rid of my 357 Maxi a couple of months ago.

Can't speak for the Max but I like 1680 in small cases like 32-20 and 22 Hornet. I was told a few years back it was hard to get because it was the go to powder for the guys loading the 7.62x39 . In my experience wherever l'il Gun works so will 1680.

i perfer imr-4227 in my "39"  and it speaks for itself too.............

[Doublebass73]

After shooting the 180 grain SSP with Lil' Gun I'm not going to bother buying any 1680

tried some maxi rounds with 158 xtp s using federal small rifle primers and remington 7 1/2 small rifle bench rest primers. at standard oal even with only 18 grains of H110 I have primers expanding back into the firing pin hole! so much so that you have to hit the top of the barrel to get the action to open! Is this a result of the large firing pin on the sb 1? Am i mis reading data and over loading? It shot 140 ftx bullets with a high of 21 gr. H110 with no problem. I am putting a heavy crimp. should i try without the crimp. everyone recomends a firm crimp with h110 should i try another powder? factory 357s or 38s will get pierced primers about 1 out of 10. if i load a mid range 357 and use rifle primer no problem. but any where near upper end loads and it has issues. any advice? Am I loading  H110 too light? tried 19.0 19.5 and 20.0 all with primers bulging into firing pin hole!

[kevinsmith5]

I've done 158 XTP's with CCI small rifle primers at 20 gr of H110 with no pressure signs in my Maxi. Of course at 50 yards the bullet blows apart on impact....took out a stray cat that was raiding  the hen house at my brother's farm with one at 50 yards this past weekend and dang near disintegrated the cat.

The 158 XTP FP will hold together better than the hollow point at that speed.  Tim, Johan is no longer at Western Powder, Inc.  He was real helpful on several questions for me, sorry to see him leave.  Found this out from a fellow Marlin Owners Member I had referred to ask Johan a question.  DP

[quickdtoo]

Sorry to hear that DP, last time I heard from him was in February on the 499HE, I wish him well, thanks.

Tim, a couple of other Handi chamberings Johan indicated were on the verge of 1680 being too slow, were the 375/ 38-55 and the 444 Marlin.  I have tried the 1680 in the 444 and will be doing so in the 375 and 38-55 this summer if Montana doesn't burn up. We have some major fires going now, one is listed at over 150,000 acres.  DP

I think i am going with lil gun. Load with 22the grains and col 2.25 preduced better group than any of 296 loads. Should be around 2100to feet a second. Still no 1680I around
