MORE LOADS<br />

The heaviest loads utilized Blue Dot and<br />

either of the harder primers in .45 Winchester<br />

Magnum cases. With the Sierra<br />

l70-grain JHC bullet, 12 grains and #200<br />

primers, they yielded 1,224 fps and produced<br />

a 1.34-inch group of four shots, plus<br />

a flier. Maximum was 12.5 grains for 1,301<br />

fps and a 2.26-inch group. Th~t's<br />

640 foot pounds of energy, matching the<br />

claimed top power of the Bren 10. With<br />

# 350 primers, the same velocity was<br />

reached; cratering was excessive, even<br />

though a l.25-inch group was printed.<br />

With W-W 7M primers and everything<br />

else unchanged I got 1,271 fps with negligible<br />

cratering and a L43-inch group.<br />

I grouped and clocked a total of 33 different<br />

loads with the Sierra l70-grain JHC<br />

bullet and only a few maximum and overmaximum<br />

combinations grouped over two<br />

inches. This bullet is a top choice for almost<br />

any purpose,.including hunting.<br />

Bullseye gave good loads; 6.0 grains behind<br />

the Sierra 170 gave 1,074 fps and<br />

made a 1.3 I-inch group. Upping that to 6.5<br />

grains produced 1,123 fps, and an even better<br />

l.28-inch group; but the # 350s cratered<br />

too much. Unique (7.0 grains) in<br />

strong brass gave a fine one-inch group<br />

(941 fps, W-W ·7Ms) and in Federal .45s a<br />

L23-inch group (i,Oll fps, CCI # 350s).<br />

For target and practical shooting, cast<br />

bullets were excellent. SSK offers two new<br />

designs, a truncated cone (TC) and a<br />

roundnose, both weighing 185 grains.<br />

Driven at 1,000 fps, either meets IPSCs<br />

"major caliber" requirements. I made severalloads<br />

with the cast 185-grain TC and it<br />

grouped brilliantly.<br />

For a good medium load, 6.5 grains of<br />

Winchester 231 in .45 Winchester Magnum<br />

cases, with W-W 7M primers, gave<br />

1,060 fps and produced a 1.40-inch group.<br />

With 7.0 grains the group was a tight<br />

L04-inch, but the # 350s cratered and<br />

some leading began to show up at l,ll4 fps.<br />

Blue Dot (il grains) and 7M primers combined<br />

to make a L04-inch group at 1,097<br />

fps.<br />

In W-W .45 ACP brass, 7M primers and<br />

7.0 grains of 231 behind the 185-grain TC<br />

produced another L04-inch group at 1,077<br />

fps. Unique (7.0 grains) pushed that bullet<br />

to 990 fps, grouping 1.13-inch and 10 grains<br />

of Blue Dot grouped almost as well: 1.28<br />

inch at 987 fps.<br />

One group showed that the cast 185­<br />

grain RN did nicely: 1.48 inch with 6.~<br />

grains of Winchester 231 for 1,061 fps.<br />

I fired two groups with the Sierra 210­<br />

grain JHC, both with 6.0 grains of powder<br />

in Federal .45 ACP cases and # 350 primers.<br />

Winchester 231 gave 956 fps and a 1.36-<br />

inch group, and Unique made a neat 1.16-<br />

inch group at 854 fps. Much more could<br />

THE DEPENDABLE DNE.<br />

The solid all-steel frame construction of Charter's Police Bulldog makes<br />

this 6-shot a .38 Spl. you can really depend on. Charter's innovative engineering<br />

makes them virtually stronger and more reliable because there's no side plate to<br />

weaken the frame. You get rugged "dry-firing" endurance that only our unbreakable<br />

spring-loaded Beryllium copper firing pin can give.<br />

Here's a 6-shot that's an honest-to-goodness 6-shot -<br />

no need to leave<br />

an empty chamber for safety, because the Charter hammer block design is truly<br />

safe. The extra-wide trigger of the Police Bulldog must be in full rear position in<br />

order to fire.<br />

Charter offers the Police Bulldog in a choice of models with 2" or 4"<br />

barrels and with regular extra-wide hammer or "no-snag" pocket hammer.<br />

Checkered panel, neoprene, or square butt grips come standard according to<br />

model, but grips are interchangeable within all models. This one has the guts for<br />

"+P" ammo!<br />

For dependability... choose an all-steel frame ... and for a lot more<br />
