This is my idea:
APS Raptor receiver(still in developement unfortunately)
20 moa rail base
Lilja 1-8, 6 groove #8 contour, 3/8" heavy flutes
HS Precision DM system
APS PK muzzle brake
McMillan A5 Adjustable CP stock
NF NXS 5.5-22x 50mm NP-R1
I am getting ready to take this rifle to Oklahoma on an exotic hunt for Axis, Oryx and possibly Aoudad or Corsican sheep.
As it will be much warmer there then here, I toned my load back to make sure it will be comfortable in the warmer temps in OK. This rifle will do 3250 fps with the 240 gr SMK but I have pulled the throttle back to 3140 fps with the same bullet using 96.0 gr Retumbo and a CCI-250 primer. OAL is 3.555" which is very short but the rifle is set up for the aluminum tipped wildcat bullets when they become available with a jacket that can handle the strains of the 300 AX.
This rifle started out with a DE four port brake but now wears one of my own new "Painkiller" muzzle brakes
That would be my idea of the ultimate long range big game hunting 30 cal rifle. I also substituted the Burris Xtreme Tactical rings with a set of 0.885" tall NF Ultralight rings.
My only complaint about the 30 cal is that it has really been left behind as far as high BC bullet selection goes. The best commerical bullets out there for the 30 cals will get you only 0.710 and thats the 240 gr SMK. There are a host of 200 to 210 gr bullets that will get you in the 0.590 to 0.640 range but thats it as far as expanding bullets.
The Wildcat bullets will be a big boost to this but we really need a legit big game bullet in the 210-215 gr bullet weight with a BC in the .8 to .85 range. With modern bullet designs, this is certainly possible and practical but appearantly there is not enough interest.
The 300 is by far the most popular american caliber but in performance, the 7mm can match it in BC and outperform them in velocity in many applications and the 338 has higher BC bullets and do not give up alot in velocity. Plus they have the advantage of longer barrel life and more autority on heavier game at long range.
With the right bullets the 30 cals could come into their own but for now, the big 7mms and 338s simply are better choices for long range shooting in my opinion but all have their advantages and disadvantages.
Good topic. DO the 338 next and I will have another earful to offer!!!
