These are always fun to work with. Love the big 50s.
this is one of my HBR rifles i build. This one uses the very large BAT LX receiver with 40 moa base, 34" stainless, fluted, bartlein 1-15 twist heavy straight taper barrel. McMillan Beast stock, Jewell trigger, and my Super 6 port PK muzzle brake. Roughly 38 lbs with vortex Razor HD in the saddles.
customer wanted to use an easy to find bullet so we went with the old work horse 750 gr Amax which admittedly is rather average ballistically these days but is accurate and good all around 50 cal.
this rifle is chambered in my 510 Allen Magnum wildcat which is my version of an improved 50 bmg wildcat With my shoulder angle and case body taper design to offer great performance at max working pressures.
worked the load up using H50bmg again as the customer wanted easy to find components(have lots of this on the rack). We decided on two loads after load development was done. A mid level load, 250.0 gr which produced 2900 fps (14,000 ft/lbs energy) and a top performance load that produced a solid 3000 fps (15,000 ft/lbs energy).
one would not expect to feel this much difference between these two loads and while the 2900 fps load is significant, its much more comfortable then the 3000 fps load!!
not a small round!!
. The 510 AM also has the advantage of being able to shoot quality 50 bmg ammo safely. I say quality because most surplus grade ammo will not even fit in my chambers. those that will, are totally safe to shoot and EXTREMELY mild as far as recoil goes.
tested this morning at 580, 1025, 1340 and 1590 yards as the customer ordered the rifle with drop chart developed as well and once zeroed this big girl was dead on for drops out to 1600 and all the way back.
These rifles are not my money makers but they are what i am passionate about and a big reason why i got into the business. Even the reason for my call sign of Fiftydriver!!
while the 510 AM has been out classed by my 510 Maximus and 458 Maximus as far as sheer ballistic performance, its still an extremely user friendly option with huge performance. With this set up, the Vortex Razor gen 2 will allow dial up shooting to 2400 yards using the main crosshair, then you have the reticle reference points over that. Supersonic velocity is maintained to past 3300 yards at my elevation. While the 510 Maximus will push this to 3500-3600 yards and the 458 Maximus will extend past 4000 yards, neither are as user friendly. The 510 AM is just hard to beat for fun all around extreme performance in the 1/2" class rifles.
