Thread: 284 win slow speeds

Just a comment on Norma brass. When I went to 284 for F Class I was already aware of guys only getting 2-3 loads out of sized up Norma 6.5/284 brass at which point the primer pockets gave out. They were however using WARM loads. I went straight to sized up Lapua and had no issues with 180gr Hybrids at 2820. Obviously my apples were different to the OP's as my barrel was 32" but this posting is more around Norma brass.
I did get in some Norma 284 brass from the States which supposedly was stronger in the base. I never got to fire that brass though as I quit the 284.

Just out of interest what are the 7mm08 guys getting with 162-165 grain projectiles?

Been flip-flopping about a 284win win build but my 20" 7mm08 tikka does 2630fps with 162gr ELD-M without leaning on it too hard. Doesn't seem like much gain for the hassle.

Stick with the 7mm08 unless you really want to go shorter. That's damn good speeds. The 284 will just let you keep those speeds at around 16 inches barrel length.

An extra 200fps is definitely worth it, just got to use the right powders. If you only want to shoot to 500 yards then I agree the 708 with short bbl will do the job nicely

Why I rebarreled my 18inch 284.
Just couldn't justify the extra powder for a few extra fps.
When my 18inch 7mm08 was good enough to harvest deer at 500meters with the 162gr Amax.
So while the 7mm08 is now a 25 inch 7mmcreed the 284 is a 18inch 7mm creed and is currently throwing the 130gr speer @2750 during fireforming and break in
