Gelatin
Gelatin was measured for calibration (Temperature 37-41 degrees, BB penetration 3.25”-3.75”) and shot within 20 minutes of removal from refrigeration. *Note – because of very windy conditions, we were unable to test the velocities of the BB’s, however temperature and penetration were within parameters.
Rounds
San Angelo PD tested:
40 S&W 180 gr. Gold Dot and 40 S&W165 gr. HST & SXT
45 ACP 230 gr. Gold Dot, HST & SXT
Test Events
Bare Gelatin
All rounds typically perform well in bare gelatin, which is the easiest test event. It is the benchmark test for bullet performance. Past and current hollow points were designed to expand 1.5 times the original bullet diameter. Federal HST rounds were engineered to expand more than twice the original diameter in bare gelatin.
Federal HST 40 165 gr. Expanded 42% more than the Winchester SXT and retained 3.45% more weight.
Federal HST 45 230 gr. Expanded 30% more than the Winchester SXT and retained 8.18% more weight.
Bullet Cal. / -------------- Weight --- Penetration ------- Expansion --- RetainedWeight
Speer Gold Dot 40 S&W ---- 180 gr. ------ 13.00” ------------- .59’ ----------- 98.72 %
Federal HST 40 S&W ------- 165 gr. ------ 13.50” ------------- .81” ----------- 100.12 %
Win. SXT 40 S&W ---------- 165 gr. ------ 15.25 -------------- .57” ------------ 96.67 %
Speer Gold Dot 45 ACP ------ 230 gr. ------ 13.25” ------------ .71” ------------ 99.96 %
Federal HST 45 ACP --------- 230 gr. ------ 13.25” ------------ .97” ------------ 99.35 %
Win. SXT 45 ACP ----------- 230 gr. ------ 13.50” ------------ .75” ------------ 91.17 %
Heavy Clothing
All Bullets performed well in Heavy Clothing. Federal HST again demonstrated the design expansion characteristics and outperformed all tested rounds for expansion.
Bullet Cal. / -------------- Weight --- Penetration ------- Expansion --- RetainedWeight
Speer Gold Dot 40 S&W ---- 180 gr. ------ 15.00” ------------- .65” ------------ 99.17 %
Federal HST 40 S&W ------- 165 gr. ------ 14.00” -------------- .75” ----------- 100.25 %
Win. SXT 40 S&W ---------- 165 gr. ------ 14.00” -------------- .65” ----------- 101.58 %
Speer Gold Dot 45 ACP ----- 230 gr. ------- 14.75” ------------- .71” ----------- 100.09 %
Federal HST 45 ACP -------- 230 gr. ------- 13.00” ------------- .96” ------------ 99.26 %
Win. SXT 45 ACP ----------- 230 gr. ------- 14.00” ------------- .81” ---------- 100.13 %
Auto Glass
Auto Glass is the toughest and most difficult of all barrier tests.
ATK’s bonded Speer Gold Dot .40 & .45 both stayed together through Auto Glass.
Federal HST and Winchester SXT both experienced core jacket separation in the .40 165 gr., however they stayed together in the .45 230 gr.
Bullet Cal. / -------------- Weight --- Penetration ------- Expansion --- RetainedWeight
Speer Gold Dot 40 S&W ----- 180 gr. ------ 15.25” ----------- .51” ------------ 87.33 %
Federal HST 40 S&W -------- 165 gr. ------ 14.0” ------------ .48” ------------ 59.88 % **
Win. SXT 40 S&W ----------- 165 gr. ------ 12.25” -------- .57 77" ------------- .52 % **
Speer Gold Dot 45 ACP ------ 230 gr. ------ 15.5” ---------- .65” --------------- 98.39 %
Federal HST 45 ACP --------- 230 gr. ------ 15.5” ---------- .64” --------------- 90.65 %
Win. SXT 45 ACP ------------ 230 gr. ------ 15.5” ---------- .60” --------------- 90.09 %
** Core jacket separation
Wallboard
All rounds performed as designed through wallboard. Again, Federal HST had superior expansion to the Winchester SXT.
Bullet Cal. / -------------- Weight --- Penetration ------- Expansion --- RetainedWeight
Speer Gold Dot 40 S&W ----- 180 gr. ------- 14.25” ----------- .64” ---------- 98.72 %
Federal HST 40 S&W -------- 165 gr. ------- 12.25” ----------- .72” ---------- 95.82 %
Win. SXT 40 S&W ----------- 165 gr. ------- 14.50” ----------- .64” ---------- 99.21 %
Speer Gold Dot 45 ACP ------ 230 gr. ------- 15.75” ----------- .63” --------- 99.78 %
Federal HST 45 ACP --------- 230 gr. ------- 14.5” ------------ .86” --------- 99.35" %
Win. SXT 45 ACP ------------ 230 gr. ------ 16.25” ----------- .73” --------- 100.00 %
Plywood
Plywood is second only to glass when measured in terms of bullet failures to expansion and performance.
Federal HST performed as designed, with no failures and great expansions. While Winchester SXT .40 165 gr. plugged and the Gold Dot .45 230 gr. also plugged.
Bullet Cal. / -------------- Weight --- Penetration ------- Expansion --- RetainedWeight
Speer Gold Dot 40 S&W ---- 180 gr. ----------- 14.25” -------- .64” ------------- 98.72 %
Federal HST 40 S&W ------- 165 gr. ----------- 12.25” -------- .72” ------------- 95.82 %
Win. SXT 40 S&W ---------- 165 gr. ----------- 14.50” -------- .64” ------------- 99.21 % *
Speer Gold Dot 45 ACP ------ 230 gr. ---------- 15.75” -------- .63” ------------- 99.78 % *
Federal HST 45 ACP --------- 230 gr. ---------- 14.5” --------- .86” ------------- 99.35 %
Win. SXT 45 ACP ------------ 230 gr. --------- 16.25” --------- .73” ----------- 100.00 %
