Got to test my new .243 AI on some rock chucks today

[Woodycreek]

I am being strong armed by "others" to go to these Amax rounds - so I am not opposed to loading up a few, just more shooting for me!

:mrgreen:

IME the 52 Amax is about equal to the 50 and 55 Vmax in ballistics (both external and terminal)... The bigger ones seem to act about like a Ballistic Tip of similar ilk... I've shot a few prairie dogs with the 105 Amax out of the .243... and they get hammered pretty good.... but the 70-80 bullets (TNT, Vmax, NBT, Blitz, whatever) seem to offer the most Air Gopher.

Most of my p-dog shooting has been done with a 22-250 in a 14 twist barrel that will not stabalize anything over 55 grains. The BCs on the lighter 224 cal bullets don't allow for high percentage shots for me at ranges over 400 yards if there is much of a wind. After watching Jeff shoot 75 grain Amax bullets in a 223 with an 8 twist, I would say there is less expolsion with the Amax than some you mentioned, but the higher BC sure helps in bringing the hit percentage up in winds over 10mph. Velocity will play a factor in the impact results (Air Gopher :mrgreen: ) as well, but if you are only getting close it isn't much of a show either.

This is why I have decided to have a rifle built that will shoot heavier bullets with high BC's in a 6mm caliber rifle. I like the 243 or AI version, but want a lighter recoiling caliber so I can watch the show through the scope.

Just get that 243AI and put that a suppressor on. I know you want one! It's better than putting a brake on it and not that loud. Scratch that! You live in one of those backwards states.

Yeah...one of the commie states if you look at what we send to Washington :roll: . Think the 6BR is the caliber for me buddy.

Why not do a 22-250 with a twist fast enough for the 75 grainers? Just wondering as that would be a cool rifle to me. Lower recoil that a 243 and still high bc'ed bullets? Just asking. I am in my concept of operations phase of this whole PD shooting deal. :twisted:

 

[IdahoCTD]

A 22BR IMP. would be cool too. Like a dasher based 22BR or BRX. My 22BR get's damn close to the same velocity as a 22-250 now.

 

[Woodycreek]

That 6BR would be a cool one. Low recoil and high BC bullets.

I am going to do that with the #1 Scott. I might even make it an AI just to give me a little extra umph. I just know that the #1's will never be as accurate as the a well built bolt rifle and the 6BR is one of the most accurate calibers out there that can shoot a high BC bullet with very little recoil. I don't want a muzzle brake on the rifle because of the dust and noise factor when you are shooting 100's of rounds in a day like you do in a p-dog town.

What is the 22Brx based off? not familiar with that one.

 

[IdahoCTD]

The .22 version isn't that popular compared to the 6 but here are the various BR improved cases.

Thank you...very informative. The Dasher is in consideration as a way to shorten flight time. I'm not sure it is enough of an improvement over the original BR to make it worthwhile for me. It sure is fun to know there are great options our there to play with.

 

[IdahoCTD]

The nice thing about the BRX is you can use standard BR dies backed out. The Dasher requires custom dies but because it's popular those are relatively easy to come by too. They just cost a bit more.

 

[257 Ackley]

Yeah...I'm starting to find out that you pay a bloody fortune for custom dies :evil: . I guess it is the price we pay for calibers with a little more fun factor in them.

 

[IdahoCTD]

I still don't have FL dies for a few of my guns because of that. I actually wish I would have had them made 10-15 years ago because they are easily double now. We got creative for reloading or used a lot of Hornady generic neck dies and their seater dies.
