20 TACT

[niceone]

what shoots best in yours any one tried 30-35 berger ? what load data do you have ..............

niceone,

I wasn't sure if you were asking just about bergers or any 20 cal pill. My favorite load is 23.5 grains of H4198 and a 32 grain Hirnady V-Max. I can shoot three of them into one ragged hole. I use IMI brass exclusively. This particular rifle has a Lilja 1:12 twist.

I don't know if you've seen this article, but there are some good Tac-20 loads in the Tac-20 section near the end of the article:

Let me know if you have any further questions.

Kory

40 Grain Berger BT Varmint Match bullets,lot 1342) seated
to 2.270 OAL using Dakota Lapua brass with CCI 450 primers.
Bullets & cases weight sorted, powder thrown from Harrels
measure.

24.8 grains N-133 5 shot 3 group agg = .309 smallest = .140

25.0 grains N-133 5 shot 3 group agg = .548 smallest = .482

25.2 grains N-133 5 shot 3 group agg = .641 smallest = .458


Same as above except using 24.8 grains of Benchmark, all components but primers
weight matched. I measured the raw group anywhere from
.417 to .419 at 200 yards

Looks like slew & I found a similiar sweet spot for respective rifles with N-133, he at 24.2, mine at 24.8, I have a 1/12 Shilen select and used CCI 450's.


Reduce your starters to be safe!!!!

PS I am working with 10X now also,.... too early to report however.

My favorite load for my boltgun Tac .20 is 32 gr V-max with 25.5 gr Re 10X lit by CCI BR4s. Bergers may shoot better in it but V-maxes are cheaper for PDs. My .20 PPC likes 40 gr Bergers best with VV N-133. I shoot 32 gr. V-maxes over 27 gr. TAC in my Ar-15 Tac .20

I shoot the 40 Vmax with 2230 powder

32 gr VMAX w/ 25.7 gr. 10X 2.220 oal, rem 7.5
32 gr. vmax w/27.0 gr 8208 2.220 oal rem. 7.5
Both these loads are into the lands, and are max or near max loads in my rifle, which has a lilja 1-11 twist with no freebore originally cut into the chamber. 39 gr. Blitzkings loaded over 25.5 gr. H322 w/ rem. 7.5 primers oal 2.220 ( this is not into the lands) is my go to load. 25.8 gr. was somewhat sticky so I cut back to enhance brass longevity. I would also consider this a top end load, so work up carefully.

I can only say that for the 20 Tac. AR-15 uppers we build, my normal test fire load is 24 gr of N133, a BR-4 primer and a 32 gr Sierra Blitzking shot magazine feed at magazine length. That load in many brand new AR-15 uppers has delivered numerous sub 1/2 min groups at 100 yards just during test firing with no specific load work ups or anything and no barrel break in.
