Folks,

I am really interested in this caliber and would love some additional information regarding it. A-Square is the only manufacturer that I'm aware of who makes ammo for it. What is this cartridge based on? What barrel chambering would allow for conversion? What twist, contour, and length would be the best for this caliber? Looking at the limited ballistic data I could find, this seems to be a typical cartridge in the A-Square/Lazzeroni mold - exotic, with speed and power to burn.

Thanks in advance.

"The 300 Pegasus was introduced in 1994 and is based upon an entirely new case that features a 0.580 inch head size. The rim is essentially identical to the 378 Weatherby Magnum case, but the design has no belt. Therefore, case capacity is substantially greater for any given cartridge length."

It would seem the .30-378 does within a couple of grains of the same thing with more widely available and cheaper components.

i think aspade has a point. pegasus stats are better, but at what cost?
30-378 or 300 w mag w/ a light bullet are nearly as good, and who knows how accurrate the pegasus is? may be too radical for practical shooting.

300 Pegasus is aptly named . . . it's rumored to exist, just like it's namesake. Actually I've learned a lot about this caliber after posting this thread initially. I even picked up a 10-rd. box of A-Square ammunition from Midway - they had it on clearance. Anyway, I don't think I'll be pursuing this as a rifle project, at least for a while, due to a lot of factors. Firstly, the two possible actions I was considering using have fell through. Montana Arms cancelled their Pro Hunter action and Olympic Arms' BBK Magnum action is being re-designed and re-tooled. They won't have anything available until the latter part of this year and that's too late for my school project. 300 Pegasus requires a minimum magazine box length of 3.75" and to my knowledge, there are no other actions made with this dimension that are under $1K.

What about the Lazzeroni 7.82 Warbird? It actually surpasses the 300 Peg. in terms of ballistics. It's rare itself but more readily available than the A-Sq. round.

yeah, im not a smith really, so i think the best bet for me would be the 300 weath. mag, for long range. up close, a 30-30. and for smaller targets i love my 25-06.
