On another thread was the below post, as i did not want to highjack thread I thought i might start a new one.
>>Where do you get teh VLD and ULD bullets???
>>Well, for lower velocity rounds, under 3200 fps in most occasions, Bergers VLD bullets are very quality bullets. In fast twist barrels they just tend to not like things much over 3200 fps in a 1-8 to 1-9 twist barrel.
>>Hornadies A-Max bullets are much the same way as the Bergers but I call these a semi-VLD bullets. They just do not quite run with a true VLD bullet ballistically. THey do however have better on game performance at long range because their polymer tip initiates expansion better then the HP match bullets.
>>Again, for over 3200 fps there are better bullets.
>>Now another semi-VLD design is the Sierra Matchking. Again I call them Semi because some of their designs do not offer true VLD ballistics. Others such as the 240 gr .308 and 300 gr .338 are VLD designs.
>>The Sierra Matchkings have a thicker jacket then the Bergers or A-Max bullets and will generally accept velocities 200 to 300 fps higher then these other two match bullets.
>>Personally, from what I have seen testing the Wildcat Bullets, I would use these for any VLD or ULD design. These bullets offer extreme ballistic performance in the ULD family of bullets. One example is the 156 gr Rebated Boattail in .257" that I use in my 257 Allen Mag. This bullet over 500 yards has a B.C. of .810 with a muzzle velocity in the 3100 to 3300 fps range.
>>Wildcat bullets offers bullet options that I have yet to find from anywhere else. YOu can get +.800 B.C. numbers but in a bullet built with a heavy tapered jacket to perform like a premium big game bullet.
>>Here is my contact informtion for Wildcat Bullets: email@example.com
This is where I shop!!!
Well, Kirby thanks for the info. I contacted Richard at wildcat bullets and he said he had the 169.5 gr. rebated boatail ULD being the lightest and the heaviest was a 225gr. rbbtuld. All are built on j-4 jackets and that bullets heavier than 225 can be built on a harrfield jacket.
He said that twists rates for them seem to be equivalent to comparable bullet weights, the secret with the ULD's appears to be seating depth and pushing them hard, as you stated above. He said that in fact they seem to shoot better as pressure goes up and that usually a max load produces the best accuracy.
Now heres my many questions:
1: in a .308 the 1 in 12 twist rate would stabilize how much lead in your opinion? in the wildcat ULD's. 169.5gr or more?
2: with max loads how long before barrel failure or fatigue with my 700 LTR? Don't worry just looking for your opinion based on your use.
3: How high or what type of velocities do you think are realistic and are the ULD's of benefit in this round?
4: When you use these ULD's, what type of seating depth do you find works best? Just touching or just off or something different?
