ULD .277" bullets arrived...

Though you guys would be interested in seeing these little beauties.



These are the 130 gr Ballistic Tips on the left and the 169.5 gr Wildcat ULD Rebated Boattails on the right.

Initial tests are showing a B.C. of .748. Now if my 270 Allen Magnum will hit its projected velocity of +3400 fps we will have a HELL of a long range rifle with moderate recoil.

Just thought you may be interested in these new .277" ULDs. I will be sure to post pics when bullets start flying.

Good Shooting!!

Re: ULD .277" bullets arrived...

LarryJ,

The Allen Magnum rounds are a family of high performance non belted magnums designed on a full length 338 RUM case with extensively modified shoulder angle and diameter.

The case is designed to offer the largest possible case capacity for the 257, 6.5 and 270 calibers. The performance goals will obviously only be reachable using bullets such as the Wildcat bullets that are being designed specifically for these three rounds.

There will be bullet weights of 130, 145, 150 and possibly 160 in the 257 AM. The 145 gr ULD has a B.C. of .730!

The 6.5mm will start at 140 gr and include weights of 160, 170 gr with a ULD in this caliber as well with a projected B.C. in the very high .7 range, possibly .8

The 270 AM will have a 130 gr conventional Bonded Core bullet as well as weights of 160, 170 and 180 along with the 169.5 gr ULDs pictured.

These rounds are designed for 500-600 yards deer and pronghorn hunting built on 8.5 to 9.5 lb sporter weight rifles.

Obviously they will also perform as excellent extreme range rounds in heavies.

I am expecting to have rifles on the range to be tested by mid Jan.

I will certainly keep all of you posted.

Good Shooting!!!

LRDT,

Believe me I am about going out of my mind waiting for the barrels and reamers but as soon as they get here I will probably in the shop all night and day getting these things up and running.

When I get the 300 and 350 gr ULD match bullets I will definately post some pics with the 300 gr SMK.

Good Shooting!!

Re: ULD .277" bullets arrived...

How much? I would like to try them out of my little gun?

I've read about BC depending about the FPS of bullets. BC changes between hipersonic speeds.

Years ago a needle point projectile was not as BC as small HP point.

I have always wondered about the true testing of long BT bullets and claimed bc? I might only have in low 500's of BC.

I study the BC tables of my .277 and have shot 1000's of Chrono loads to make the best 600 yard paper shots with 140 and 150 moly coated SPBT needal point loads out of my 29 inch stick? None of the 135's match bullets even get close to the grouping.

I would like to test yours on BR shooting at 300 just to see a group. The guys up in Arco idaho have nice BC also
