+3 What Bob said..

+4, move into .357 and it's pretty much hunting medium size game, more shots is not a concern, power is.... and of course accuracy.

IMO, distinguishing between the .30 cal and the .35 cal.... in other words aiming them at different segments of the market.... makes the most sense.... Since the .30 cal appears to have decent power right now (81 FPE) and should, at that energy be able to deliver two 7-shot magazines, I'd tend to leave it alone.... The .35 cal, however, needs more power, IMO, and if you can tune it for just ONE 6-shot clip at maximum possible power but with minimum velocity spread, I think you'd have a winner.... Since the pellets run 78-82 gr, if you can get them up to 900 fps, that would be 140-150 FPE, which should be do-able in terms of onboard air.... providing the ports are big enough.... Then by using bullets that will still fit the magazine (up to about 105 gr. or so), you could get a bit more energy and still get those 6 shots.... Personally, I think that's what everybody is hoping for with the .357....

Bob

I totally agree

[pepegraves]

MORE POWER! We are hunting so if you are out to lets say shoot a pig, your not going to need more then a clip. I would like to see a good power band on a single clip with a low ES............ 6-8 shots before topping off is all one would need, thats for the .357 for the .30 10 shots will be great!
when im out hunting I do not waste shots, I make every shot count.

that's an outstanding point of view I totally agree

+4 what Bob said. At 140 or 150 fpe and five or six accurate shots I'm an interested customer.

No doubt it can be done but we would have to do it ourselves. I would maybe start with the dia of the stem and some porting?

Too true.
Hopefully, one of GTA's resident gurus will mark a trail that can be followed without mill or lathe.

None of the airgun manufacturers seem to be approaching  900' per sec.  Do you suppose that due to the large diameter pellets they might not be flying true at over 830fps?  With those large skirts it might be easy to get them whipping back and forth at over 830fps.  Regards, Tom

I can't speak for the 35 cal but the 30 cal 44gn JSB does not like to go over 900 fps without significant loss of accuracy.  In the case of the 35 cal guns many are producing less than 800 fps.  Can you say cannon ball!

Tom

[rsterne]

The Daystate .30 cal is well over 900, with great accuracy.... and the .30 cal JSBs are winning just about everything in Benchrest now (that doesn't allow bullets), at nearly 900 fps.... I can't imagine that what you suggest would be a problem, as the .35 cal pellets are basically just scaled up versions of the .30 caliber, and because of the increase in size actually end up with a better SD and BC.... I think it's a matter of not pursuing power at the expense of shot count.... For 900 fps, that works out to 1.8 FPE per grain, so an 80 gr. .35 cal is 144 FPE while a 50 gr. .30 cal is "only" 90 FPE.... All things being equal, that means the .35 cal will use 60% more air per shot, or get about 40% fewer shots than the .30 cal. at equal velocity....

I personally would sooner have one 6-shot clip at 150 FPE than two at 90 FPE in a .35 cal.... Realistically, how many times do you need more than 6 shots of that power when hunting?....

Bob

[QVTom]

Interesting about the Daystate being > 900 fps.  Every time I bring my 30 Rainstorm with with the TJ barrel over 900 it really opens up.  Timmy stated he was shooting at 875 for the EBR.  Daystate's barrel may be more tolerant of the higher fps?

Tom

[rsterne]

It's possible.... The FT guys shoot JSBs in the 880 range in .177 cal, so it's probably just the sweet spot for ultimate accuracy with that shape of pellet, regardless of caliber.... I use 18 gr. JSB Heavies in several of my guns at 950-960 fps with good accuracy, good enough that I haven't chased lower velocities in search of better.... It's good enough for ground squirrels out to 106 yards.... I don't hit every single one on the first shot, but my success rate is good, and inside 50 yards I seldom miss (unless they duck!).... My Hatsan .25 cal will shoot groups you can cover with a dime at 50 yards with JSB Kings at 1030 fps, and just over an inch C-T-C at 100 yards.... so again, I have never needed to look slower for accuracy (although I am looking forward to the new 34 gr. to drop back into the mid 900s).... I don't personally have enough trigger time on my .30 and .35 cals yet to see if they have a "speed limit"....

Lets say both Hatsan's big bores are very accurate in .30 and .357. What pellet will be better on a windy day at 75 yards? 

A 35 caliber 80 grain traveling at 800 fps.

A 30 caliber 50 grain traveling at 900 fps.

[rsterne]

Not a lot of difference, it depends on the exact BC at those velocities for each pellet.... The 80 gr. in .35 cal has an SD of 0.090, and the 50 gr. .30 cal about 0.079, and they are almost identical in shape (assuming both are JSBs), so in theory the larger caliber pellet should have a BC about 14% better.... The BC is likely a fraction better at 800 fps than at 900 as well, so my guess would be the .35 cal.... Only velocity measurements downrange will tell you for sure....

So, where are the great accuracy results?

Rick Eutsler from airgunWeb says both rifles he has tested are accurate. AGD also states the .35 is accurate. Links:

I went onto airgun depot to check these new models out. Says more on their way. I call them and they have yet to ever even  get them!!  Was told they will not get any until summer time. Why the *(&^ not just say that?? They have it written like they sold out and more are coming!!

Thats why I do not deal with them , PA says 2-15-15 they have a date , plus they do not charge you until the item ships so you can pre order and not worry about your funds being tied up forever.

Bob my gun I do not know , but when I tried JSB's over 950fps there became erratic, and when I went to a 31gr H&N I got a .500ctc 6 shot group. The JSB did not work well at High velocities. My company goes to the shot show every year and it just dawned on me to tell them to stop by JSB and see if they have some of the new .25 pellets, and if they do, pick up as many tins as they will sell you at lease come back with one tin
I have to do more testing it was the guns first time out.

hammer0419,

Sorry about the confusion on the ship dates for the new Hatsans. Unfortunately with the way our backend system runs and links with our inventory system in the warehouse whenever a gun is out of stock it will automatically add the "More On The Way" status at the top. However if you look at the button that normally says "Add To Cart" it will be changed to " Pre-Order" and there is a note directly below that that shows the estimated in stock date of 02/15/2015, that is the date that Hatsan has said we should be receiving them.  I am working with our web development team to change the "More On The Way" notice to "Pre-Order" and move the projected in stock date up to the same line so hopefully that will clear up some confusion. Thanks for your feed back,
