Feel free to include barrel length and load if you wish.

I've got a new rifle coming, really hoping that I can get 3000'/sec with a 180 Accubond or other similar .5 BC bullet.

Thank you all in advance.
You should have no problem getting 3000' with 180's. I can easily hit 3050' with 190's (.616 b.c.) in my 300 Sherman which has very similar case capacity. I've fired 180's at 3150 with 62 grains of RL-17 with good accuracy. My rifle has a 28" barrel so a 24" would probably be about 150' slower........Rich

In my Sako 85 Finnlight (24 3/8ths bbl), 67 gr of RL 17 pushing 180 E-Tips @ 3190. H4350 is 200 fps slower. Accuracy in this rilfe is extremely poor.

Re: 300 WSM......How Fast??

With a 26" tube mine shoots the 178's at 3070 with I7828. 168's at 3150 with I4350 and 208's at 2870 with H4831sc. None of those have been hot loads. I switched from 215m primers to the 210's and saw my veloctiy spreads drop. H4831 has turned in the the most uniform velocities in my rifle. The 208 load is one I am still playing with but has been the most accurate at 1/4 min. The others have run 1/3 to 1/2. I know some guys have had great luck with ramshot as well but I haven't played with that.

Very greatly appreciated

Keep them coming please, I'll eventually use some of this for my initial load testing/development.

Kirby tells me that the rifle should be included in his next batch.

Thank you all again.

Borden Alpine magnum action , 1-10 Lilja barrel with APS slim PK brake (approx 26-27" with brake), McMillan Remington Hunter stock with swirled colors and Pachmayer Decelerator pad, Jewell trigger...........Plan is to keep weight under 9lbs not including scope............don't remember barrel contour for sure, #6 maybe.
