Anyone have a good & tested seating depth for Berry's new 9 MM 124 gr. hollow base bullets---this bullet is quite long

[Walkalong]

I have shot it at 1.140 to 1.145 OAL in 9MM with good results. I have loaded it light with fast powder shot it and the X-Treme 124 Gr RN at the same OAL, with the same charge, and it resulted in around 75 FPS less velocity for the Berrys. Due to the hollow I expect, despite being deeper in the case. It can obviously be run hotter, but this is one side by side sample I have.

I like this bullet in the .38 Super @ 1325/50 FPS. (In a gun set up for hot .38 Super)

Berry's new 9 MM 124 gr. hollow base bullets

I seat mine at
1.070 for my keltec pf-9 (short throat) with a reduced load of Universal. 4.0 gr.
1.125 and 1.135 for my SR-9. I've not experienced any problems at all with any of them.

Are you talking about the TP series? I just checked the website. I am using the standard double-struck HBFP.
I have never used the TP series.
sorry

The 124 gr HBRN-TP bullet has longer bullet base but with most small flake/ball powders, it won't compress the powder charge.

I have used 1.135" OAL (that's comparable to OAL of 115/124/125 FMJ) and feeds/chambers reliably in various pistols.

Berry's 124 gr RN, 124 gr HBRN, 115 gr HBRN and Winchester 115 gr FMJ RN:

@ TT

@bds

Berry says that these are more accurate than std bullets.
What do you think?

[bds]

Definitely more accurate than regular plated RN bullets with solid base.

In my opinion, the hollow base expands to seal with the barrel better to produce more consistent chamber pressures. My 9mm reference load has been with 115 gr FMJ with exposed lead base that allows expansion of bullet base but my range tests have shown that HBRN loads can be more accurate - http://www.thehighroad.org/showthread.php?p=7266869#post7266869

Following were shot from Glock 22 using Lone Wolf 40-9 conversion barrel at 15 yards off hand (target squares are 1 inch).

Reference load - Winchester 115 gr FMJ RN

Thanks everyone for all the info.
Will Berry sell 9MM 115gr HBRN-TP in 250 box-- I only see 1000 ???

[bds]

You may want to call Berry's customer service and ask as they recently added the 115 gr HBRN-TP bullet and their website may not have been updated.

Berry's 124gr HBRN over 4.4gr HP-38 with a 1.135 COL is my go to load in 9mm

[rfwobbly]

Berry now makes at least 3 "hollow base" bullets for the 9mm.

Generally speaking, if you've been shooting their 124gr RN, then you can sub in the 124gr HBRN at the same load and OAL. The HB bullets are longer, but the void in the middle keeps the case volume the same. There will be a slight difference due to the longer bearing surface, but IME the 2 loads worked out to be very, very similar. Same goes for the 124gr HBFP vs the 124gr FP.

I have not tried the 115gr HB but have seen some great range reports. Some say they are enough to make you believe in 115gr again !
