Rel 15 works well with 160's as well.
John In my Winchester Featherweight,it'sIMR-4350 with a 160 gr Sierra GK. Getting an average of 2710 fps from a 22" barrel. In the CZ it's H-4831 and a 160 gr Nosler Partition. IIRC that load is in the 2750+ range from a (almost) 24" barrel. The CZ I can seat the heavier bullets out to 3.330". With the lighter bullets well.... ![[Linked Image]](http://i1243.photobucket.com/albums/gg546/elkhunterinnm/IMG_0421.jpg) ![[Linked Image]](http://i1243.photobucket.com/albums/gg546/elkhunterinnm/IMG_0425.jpg) I don't use the above load,backed off a little bit and get better accuracy. Not that there is anything wrong with the group in the pic.

W-W brass
160 gr Accubond or Deep Curl
50 gr H4831
CCI BR2
Use in modern rifle only. Thanks for the mention of Speer's Deep Curl bullets. I had an email exchange from one of the techs at Speer and he mention in passing to use only the data published on Speer's website for the Deep Curl bullets. When I asked why he said that those bullets act differently from a normal C&C so it's best to stay with data published specifically for them. I just thought they were a regular bonded bullet, and reloading manuals put out by folks like Hornady and Nosler don't make a distinction between their bonded and C&C bullets. What are y'all's thoughts about the tech's advice? Thanks.

Rev, I think it is wise to do as they suggest, the Deep Curls construction (plated jacket) is much different from C&C or other bondeds. I followed the data Speer provided designated for "Modern Strong Action Only" which maxes at 51 gr. Happily it coincided with the load I had already worked up for the NABs which came from an old issue of Handloader, also for modern rifles. Interestingly, IIRC the Poobah has said he uses the same powder charge with 160 TSX's which is either a case of great minds thinking alike or fools seldom differing, probably the latter.

I agree. If there is anything unique about it, better safe than sorry.

Just picked up some 140 gr. VLD's.
Started with 48 H-4350,got 2775 into a 3 shot 1/2".
Couldn't believe it.
I might be done,or may still try to get to 2850 or so.

I used to use 760/414 in the 7x57, and it did provide outstanding velocities with good accuracy--in what might be called normal temperature ranges. But eventually I found it didn't work nearly as well in real cold or heat, proving too erratic.
Eventually, like many people who've posted here, I settled on H4350, which is MUCH more tractable across a wide range of temperatures. But another problem with the 7x57 is that throat length is all over the place in different rifles. I've owned rifles that could take over 50 grains with 140-grain bullets without the slightest sign of distress, and others that couldn't take 47 grains.
Consequently I just advise using enough H4350 to reach a certain velocity level, and leaving it at that. Of course, velocity will vary depending on barrel length, but 50 fps can be added to 24" barrels or subtracted in 20" barrels from the following suggestions for 22" barrels:
120's: 3150
140's: 2900
150's: 2800
160's: 2700
175's: 2600
Ramshot Hunter also appears to be a pretty good choice, and is a little slower than H4350 so might be capable of more zip, especially since it's a ball powder so more can fit in the case. It certainly works great in the 7mm-08. But I haven't used Hunter enough with all bullet weights to come to a firm conclusion yet--except it's noticeably more consistent in varying temperatures than 760/414, and burns a lot cleaner as well. This matches my experience as well, just bear in mind that it may take a lot more than any book shows to get these normal velocities in a long throated rifle. I have been tempted to try Hunter as well, but I have probably 15 pounds of H414, so....haven't yet. It takes 50 grains in mine to get 2750 with a 160 partition in mine, as an example. 52 with 140 TTSX

Hello MD,
Agree! Those velocities/bullet weights matches very accurately my findings after 40 years reloading the 7x57.
Best Regards
