EVOL HPS HPA to shoot high sectional density, high BC slugs

[Conecrusher]

Hi,

I'm a long time reader and a life long shooter owning several custom centerfire precision rifles, Rapid, Gordon Dawson, RTI and AAA EVOL rifles over the decades.

This is a follow up to a conversation Tom C and I had on the subject of an EVOL HPA that is capable of shooting very long high BC slugs such as an NSA .257 projectile measuring 0.615 " in length at over 950 fps. Feeding these long slugs thru a magazine would be preferable to single shot loading. I think that those .257" slugs are designed with the Airforce Texan .257 in mind, but it sure would make the EVOL dominant at airgun precision shooting or NRL style competitions. It would also be fun!

Before anyone points out the multiple engineering challenges involved in meeting the goal outlined above, remember that the last several decades of development in all of the centerfire precision long range shooting platforms has been about shooting the longest possible streamlined bullets as fast as possible out of a rigid rifle. My thinking is not without precedent.

Kindly,

Mike

EVOL HPS - HPS 30 Models

We will be releasing the ALL NEW HPS EVOLs very Soon! Not all configurations will be immediately available, we will start with the Mini and the Hunter then followed by the BR/NLR models. Other than 30 caliber are the 223 and 257. Both of these are aimed at Airgun NLR and similar slug-centric...

Tom says that he will be releasing a .257 and a .223 real soon in the above post. Looks like a good start.

The day they are released is the day my wallet gets much much lighter! I am thinking .223 for its super flat trajectory. Its the very last piece I need for my A A A puzzle.

I've had the same type of conversation with Tom as well. The high BC shooting guns are in demand, but to a select market. However, with Tom's evolution of the Evol, the 'new generation' is to be more interchangable, not the one caliber platform that the majority of airguns on the market are. By doing so it opens the market up; wide open really. Because it can be interchanged for calibers fairly easily way more people will invest in it, similar to why many of us bought an Impact years ago.

A .257 Evol that can accommodate "NSA .257 projectile measuring 0.615 " in length at over 950 fps." Will get my wallet wide open!

I have not added the 257 yet but you will find performance data here when it is posted.
EVOL HPS - HPS Performance / Tune Info


NLR22 rules restrict slugs to a max of 68 gns. but there may other competitions without a grain weight limitation.

Currently the 257 65 gn NSA is running about 135 fpe without pushing too hard. These do/will fit in the HPS magazine. There is more to be had but shot count will suffer.

Thank you Tom, I appreciate your taking the time to reply.

Already have money ready to buy one once Tom has them ready. Next year will be an airgun only year for me up here.

yea i am back on my beans and cornbread diet in lieu of the upcoming year.

Beans and cornbread?!?!!? Heck I am a Raman and PB&J r8ght now. Maybe some white rice from time to time if I want to splurge! Lol
