That sounds good, always had heard horror stories about ballistic tips with jacket/bullet separation so I have never played with them. I am definitely going to try that load though. I also have a lot of 165gr core-lokt bullets so I will see what I can cook up with them. My 30-06 is also a 700 and my 7mm RM is a savage 110 - but that gun is not used much.

Hodgdon's new Hybrid 100V propellant combines the chemistry of a spherical powder with the geometry of an extruded propellant. According to the company, Hybrid 100V is ideal for use in calibers that fit H4350, and it delivers velocities not seen before in many popular cartridges, such as 3310 fps for a 150-grain bullet in the .300 Wby. Mag. Its unique small-grain, semispherical/semiextruded shape allows it to flow smoothly through a powder measure, thereby improving charge weight consistency and load density. Hybrid 100V comes in 1- and 8-pound containers, and complete data is available at the hodgdon.com Reloading Data Center.

Try the Hornady sst's and the sst interbond's they are better than the noslers and a lot cheaper too.

Has anyone tried it with a .270 and what did it crohno at?

The Hodgdon website lists it for the 270

130 GR. BAR TSX _ Hybrid 100V _ 52.2 gr _ 2994 fps _ 55,700 PSI _ 55.5 _ 3144 _ 63,100 PSI

It is listed with the highest velocities for this bullet. May have to give it a try. Wonder if this is similar to what Hornady is using in their Superformance Ammo?

I don't know, but the Hodgdon hype for the powder is that it will give you 200 fps faster or better than any other powders without excessive pressures.

It seems Hodgdon isn't sitting around waiting for things to change. I just read the following on another site;


"August 21st, 2010Hodgdon Will Introduce Two New Powders in 2011"

Hodgdon will introduce two new propellants in 2011, LEVERevolution and Superformance. According to Chris Hodgdon, these powders will allow hand-loaders to replicate Hornady’s factory-loaded LEVERevolution and Superformance ammunition. Hornady used proprietary powder blends to achieve impressive velocities in its Superformance ammo. Now reloaders can take advantage of that blending technology to get more performance from their hand-loaded cartridges.
According to the Shooting Times website, the two new powders should be available starting in January 2011: “This is welcome news to handloaders who until now have had to sit by and watch as factories make the best use of new bullets such as Hornady’s FTX and mass-produced loads that handloaders couldn’t safely duplicate. This should also be welcome news to shooters who until now have avoided new high performance cartridges over concerns about future high performance ammunition availability.”

Hodgdon data doesn't list 200 fps for the .270 Win. Maybe 200 fps over the slowest in the group. Otherwise its about 50 fps. I also noticed that in some of the loads where max pressure is typically just above 50,000 psi, they show Hybrid 100V just above 60,000 psi. Looks like I've more to learn about internal pressure. There might be some aspects of pressure duration that allows this variation.

Things will be getting interesting in the next 6 months. Who among us will be leading the exploration for new handloading knowledge?

Slim, the 50,000 is CUP not PSI !!!

en.wikipedia.org/wiki/...f_pressure

Copper units of pressure or CUP, and the related lead units of pressure or LUP, are terms applied to pressure measurements used in the field of internal ballistics for the estimation of chamber pressures in firearms. These terms were adopted by convention to indicate that the pressure values were measured by copper crusher and lead crusher gauges respectively. This was necessitated by the adoption of more modern piezoelectric pressure gauges that more accurately measure chamber pressures and generally give significantly higher pressure values. This nomenclature was adopted to avoid confusion and the potentially dangerous interchange of pressure values and standards made by different types of pressure gauges. Pressure is a fundamental thermodynamic parameter that is expressed in units of force divided by area. In the avoirdupois system, the units of pressure are pounds per square inch and in the metric system, the units or pressure are newtons per square meter or pascals. A chamber pressure measured with a copper crusher gauge would be expressed as psi (CUP) in the English system or MPa (CUP) in the metric system.

wait, there is more!

While CUP and LUP numbers were intended to be comparable to the crushing power of a given pressure in psi, the numbers are not equivalent. Since a longer duration, lower pressure pulse can crush the cylinder as much as a shorter duration, higher pressure pulse, CUP and LUP pressures frequently register lower than actual peak pressures (as measured by a transducer) by up to 20%. For example, the SAAMI maximum pressure for the 7.62 x 51 mm is given as 52000 psi (CUP), or 62000 psi (430 MPa); the .45-70, on the other extreme, is listed as 28000 in both CUP and psi (190 MPa). SAAMI standards for a given cartridge may be expressed in CUP units, LUP units, or in standard units of pressure (psi or MPa).

Now its clear as mud! Ok, the two measurements are different and not the same.

And here's more that might help you understand it better !!!

CUP is used when chamber pressures exceed 15,000 PSI
LUP is used when under 15,000 PSI
Neither are true pressures they are relative units for comparison against a set standard
When load data shows the PSI rating (as you've posted) that means a piezo gauge was employed to achieve the data instead of the crush method (cup and lup).
PSI is a true measurement.

The most important thing to keep in mind is that all 3 have independent properties. Because of this there are no formulas to convert one to the other. Conversions have been tried and there are similarities but nothing that can be dependable and safe when dealing with max pressures.

And then I had to go and find this.......obviously I've been taught from the old school !!!
Might have to change my position on my last statement.......after further investigation of course !!!

Hate it when that happens !!!

Looks like we need Dimitri to join in! A quick look shows a compelling analysis.
