Same as the first test. The impact velocity was made to duplicate modern 6.5X55 loads and .260 Rem at 100 yds. Cast bullets were approximately 1500fps.
Approximate impact velocity:
85-100gr.............2850-2900fps
120gr..................2750-2800fps
125gr..................2600-2700fps
129-130gr............2550-2600fps
140gr-142.5gr.......2500-2550fps
156-160gr............2400-2500fps
168gr..................2300-2400fps
Now I�d like to see the same results for .264 Win Mag velocities at close range�
Approximate impact velocity:
85-100gr.............3400-3650fps
120gr..................3200-3250fps
125gr..................3050-3100fps
129-130gr............3050-3100fps
140gr-142.5gr.......2950-3000fps
156-160gr............2800-2850fps
168gr..................2650-2700fps
I suspect some of the bullets that didn�t fare too well at the 100-yard 6x55 velocities would fare much worse.
Even at my 6.5-06AI velocities, I agree with GregW � the 140g Berger is not one I would choose to use, especially if close range impacts were a possibility � which they almost always are. Extrapolating the results up or down in caliber and adding velocity explains why I choose the bullets I do for my loads:
3200fps = Roberts 100g TTSX
3150fps = Roberts 110g AccuBond
2950fps = Roberts 120g A-Frame
3150fps = 6.5-06AI 130g Scirocco
3350fps = 7mm RM 140g TTSX
3200fps = 7mm RM 140g North Fork
3000fps = .30-06 150g AccuBond
2900fps = .30-06 165g North Fork
2900fps = .30-06 168g TTSX
3200fps = .300WM 168g TTSX
3050fps = .300W 180g North Fork
3050fps = .300W 180g MRX
While I�ve never used newspaper, I have tested close range impacts in clay and water and actual game and even at high velocities the North Fork, MRX, TTSX and A-Frame do well. (Haven�t tested the Scirocco of AccuBond except on game at ranges that don�t come close to �close�.)
YMMV
Thanks for all the work, Steve � good job!
