Re: 6.5-06 AI 120gr Swift - Loads??

This may be hard to read. Send me an e-mail and I will send you the spreadsheets for 6.5-284 and 6.5 WSM. Below is a section from the 6.5-284 data
All velocities are instrumental and usually at 15 feet. You can see that 3300 fps or at least 3280 possible with 56 -57 gr of N-560 propelling 130 Accubonds in at 26 inch barreled M-70. I use HBN coated bullets.

If you use the same bullets, etc., I guarantee you will gain velocity......Rich

Re: 6.5-06 AI 120gr Swift - Loads??

The same bullets in the same barrel by the same manufacturer with the same twist does not gain velocity with the WSM case. The velocity with a wide range of powders is equal or less. If there was a VV N-565 there might be an advantage. N-570 is slower than Retumbo so helps only with 140 and 160 gr bullets. I am experimenting with an 8 twist 28 inch 6.5 WSM barrel and N570 now.

Re: 6.5-06 AI 120gr Swift - Loads??

I had the same pressure results as Dano in my AI. With the straight wall it sneaks up on you. I started with Win. 25-06 brass and 4831sc, then went to 7828. After about 2 or 3 loads, the primer pockets were gone. I found that Rem brass weighs about 6g more and seems to be tougher. I only have a 10' twist, so 120s or lighter for me. I could get 100s to 3500+ and 120s to 3200. 7828 got me there, but pressure was a bit high. I tried Hunter, and found velocity was there, pressure wasn't. No more pocket problems, but did get hangfires with standard primers. Went to mag. and all is well. This is with a 28" barrel. It is now my favorite shooter. Trajectory is very flat, about 21moa at 1000. Fun to shoot with the 123A-max.

Re: 6.5-06 AI 120gr Swift - Loads??

WOW that is some pretty fast velocity with the 130's! I'm doing 3090 with the 130 scirocco II in my 6.5-06 springfield, using the N560 powder as well. I have plenty of neck clearance, so I may eventually switch from my current rem 25-06 brass to the lapua 30-06 brass, and with it I will probably swing a bit more velocity. However, it took some work getting sub-MOA with the scirrocco's, so I'm not looking forward to any more load development with this bullet.

Anyway, I was a bit confused with your posts, are you shooting a 6.5-WSM or a 6.5-06ai with 270win brass??

Re: 6.5-06 AI 120gr Swift - Loads??

I am collecting parts for a 6.5-06. So far I have a Rock Creek 9 twist light weight fluted barrel and a Bell & Carlson thumbhole stock. I have ordered a 25-06 Redding bushing die.

I own two 6.5 WSMs and a 6.5-284. I want the neck length to partially resize that the 270 or 25-06 case allows. I have some 270 Nosler brass on hand. I also own a lot of WSM dies and a reamer but I have not found anything outperforms the 130 Accubond from the 6.5-284 case. The higher BC bullets just cannot be driven fast enough to shoot flatter than the 130 AB.
