204 40 ballistic tip

[YoteSmoker]

Anyone have any experience either on the bench or in the field with these new bullets? I picked up a box to try in my new CZ 527. I will also be experimenting with 40 v-max, 32 v-max, and 35 bergers. All are test rounds are loaded and ready to try at the range on my next day off. Powders I am working with include: H322, H335, H4895, W748, and Varget. I am hoping that the 40 ballistic tip works the best and seems to be the most aerodynamic design with a high b.c. I am interested to hear from others on this forum as to bullet performance on game and paper. I put a 5.5-16.5 monarch on my CZ, so I really hope this baby shoots!!!

I had great luck with the V-max 32 gr in my CZ--when I had it.

Win 748 took them to 4195 fps. I will be trying the 40 BT's for a friend soon though.

Pop- I'm not sure if you are working with another CZ or not but this may be of interest in your load development concerning seating. The magazine oal measures 2.335" I seated both the 40 and 32 v-max to 2.325" oal leaving just .010 room in the mag and neither bullet makes it to the lands. I found the longest I can seat the 40 b-tip is 2.250" within .010" of the lands. I set the bergers to 2.310" oal.

In the CZ I had before I just sat them as close to magazine max as I could. If memory serves right the bullets were not close to the lands.

Range update: 32 v-max grouped .310" using H322
40 ballistic tip grouped .630" using H335 bettering the tests with 40 v-max, but I am still going to tweak and shrink it some more hopefully. Sidenote: could not get the 32 ballistic tips to group well in this rifle, no matter what powders I tested. Will experiment some more in the morning and post the results if it gets any better.

velocity?

 

[YoteSmoker]

Velocities averaged just over 3500 with the 40 ballistic tip and 24.7 H335 (might try to push it a little faster eventually, but nice groups)

Velocities averaged right at 4000 with the 32 v-max and 27.3 H322, this with a 25.5" barrelled CZ 527 Varmint.

I zeroed the 40 b tip at 100 yards with the 32 vmax hitting exactly 1.5" high and dead center left and right. Now, I'm going to figure out my drops/clicks at 400 yards. Both should only drop about 2.5" at 300 so I'll just put the crosshairs on a p dog's nose and let him have it. Sweetness!!

FYI- 32 Vmax has .210 BC and the 40 Ballistic Tip B.C. is .239

Here's the info I came up with converting bulllet drop to clicks using a scope with 1/4" adjustments at 100 yards.

204 Ruger 40 Ballistic Tip
M.V. 3510 B.C. .239 24.7 H335
CLICKS FPS Bullet Drop
