Hatsan big bores update

[blackdiesel]

Seem they made the barrel smaller on the .357 and it seems to have solved the accuracy problem. They also lowered the power and increased the usable shots on the .30 cal.

.357 otb making 95 fpe for 18 shots? Not too bad. Assuming they used JSB ammo, that's pretty slow though, roughly 730 fps. I'm willing to bet with a little personal tuning it can do a little better, maybe reaching 825-850 fps if the shot count were to dropped down to about 10-12

Wish they'd widen the mag & slot a little to accommodate longer ammo. Looks like it'll only take pellets & shorter bullets. But still very impressive.

Only question I have really is how many options are there wrt .30 cal ammo on the market now? besides JSB it doesn't seem to have a lot of ammo choices available currently. So the better gun at least for now just might be the .357

if I had the .30 Id just cast my own bullets/pellets, Lee molds are cheap and scrap lead is easy to come by other than taht a small ladle and a small melting pot is all thats needed.

wheel weights make good bullets and can be found really  cheap, id also do the same for the .357.

Thanks for that update, I'm going .30cal first. Im going to work some magic on it to increase power for two clips. I will be looking for 90-100ftlb with the .30cal thats my goal for that gun. with an low Es.

I know these are pre-production numbers but at this time I can't think of how these will benefit me so I'm going to wait on the sidelines for now.  I got a chance to shoot the 43 gr Eun Jin pellets in my 25 cal Sumatra and a full magazine gave me a hi of 951 and lo of 920 fps. I guess that about 84 fpe average. At 30 yards I had one flyer but 5 shots went into the same hole.  This is too similar to what the 30 cal is doing.  Plus I think there's only a couple of options for ammo available for 30 cal.   My Career Ultra I'm getting from 120-180 fpe depending on what I'm shooting and the power wheel setting so I don't need another .357 cal.  I ordered a mold to cast the 80 gr EPP\UG slugs and that will give me several options for ammo.

[Bwalton]

With the .30 I'm going to shoot long range with it, 150yards, with the heavy pellets the drop rate will be to high at long range. At 30 yards it may be ok but stretch it out to 100 or more is where I'm more concern with the weight. The 30cal JSB shooting @ a avg of 975fps will give me 94.5ftlb and a much flatter curve.

Am I the only one that sees a complete disconnect in the data on the .30 cal.... How can you go from 7 shots at 80 FPE (560 FPE) to 21 shots at 73 FPE (1533 FPE) with the same airtube?.... Makes no sense to me....

No I seen that too, but did not matter to me as I was going to dive right into it to make it do what I want it to do. I don't think that they have the real numbers as of yet.

Good question Bob.

Only answer I can come up with is that in the initial testing their combo of sizes for the valve outlets, tp and the hammer strike/dwell was way too long & the gun was dumping huge amounts of air with each shot, even long after the projectile had left the barrel, making those settings highly inefficient.
Hopefully, they'll sort those bugs out & get the mix just right before production & sales to the AG community.

I guess we need to know what he means by "usable" shots?

LEE, does NOT make any suitable molds. Caliber or length. Custom molds only possibility.

This is actually the bullet I was thinking of, 75 grain will cast @ roughly 75 grains and can be sized down to .307 or whatever dia needed for rifle bore.

I dont know if these would work of not just an idea that came to mind.

You are correct, it's lyman that makes the mold I was thinking of and NOT LEE.

I to am curious, so I sent Rick an email.  Hopefully he will get back to me soon.

Rick Eutsler was kind enough to answer my email about the difference in shot count that Bob noticed:


Joe,

The rifle was originally set to max power to accommodate the heavier JSB pellets that are used overseas (will be imported middle of next year to the US).  They are 50 grain and utilize the power more efficiently.  The lighter 44.75 grain .30 cal pellets don't and that's all we have for .30 cal here in the states at this time.  The lighter pellet just wasted the air.  By backing down the power some, we were able to not lose much on the FPE side, but gain a lot in the shot count.  I was just out videoing yesterday and got some really great groups with the .30.. 75 yards may be under 1" shooting off sand bags.

Cheers,

Rick Eutsler

In the .30 cal PCPs I have shot, I haven't seen a huge difference in air usage between 45 gr. and 50 gr.... and yes, the 50 gr. are available in the USA and Canada under the Daystate name.... I guess we'll see eventually, still makes no sense to me....

I'm hoping these guns will be around $400 or $500 or is that wishful thinking?

A new 22 and 25 cal BT65 cost more than this so what do you think?

[kayak1979]

BT65 .25 new is right around 550 bucks...I'm just asking a simple question in what the price might be.  No reason to get snarky.

[Bwalton]

They are going to be in the $750- 800 range A BT65 is $679 the Hatsan Galatian QE is $769.99
where is a BT65 new for $550? Maybe old style, old stock
