Thx mucho Dr Mike!!

Would someone mind running a QL for me on the following data points, bullet, powder, etc. I ve been working with some mild loads with these components in a new rifle but would like to get some projections to see where I might be able to work up towards. 7-08 Rem 22” barrel 9.5 twist N550...

I don’t think it’s too much spin , 3134 fps out of an 8 twist would be 282,000 rpm. That s/b perfect. Something seems odd to me …

When we ve shot ladders typically 2 minutes between each shot; on overbore cartridges like 257 Weatherby and other magnums we d wait 3 minutes. Those were with med weight sporter barrels and 10 shot ladders.

+1 to Salmonchasers advice. Stay a little off lands for hunting ammo and don’t worry about oal if: -Ammo fits mag -You ve got a reasonable amount of bullet/pull in the case

Money for them ; plan on Federal ammo and components costing you more over the years ahead. Those PE hogs gotta reward themselves AND ruin the work environment for existing employees; it s their (PE) standard “playbook” ….

More like 300 fps if loaded to comparable pressures …!!

I m old but the Solid Base was the Daddy to the original Ballistic Tip. ( SB + plastic tip = Ballistic Tip) So that same thick base that BT is known for came from the Solid Base.

Hodgdon gives H4895 reduced load guidance. They do not give it for IMR4895.

A well chosen bullet and a solid 270 reload gives up nothing to a factory loaded 7 RM. It does let you pack one more cartridge in your rifles magazine 😁

Start at 55 and work up …. At 57 grs you ll most likely be at or near max. Depending on brass used (capacity) I find 56-57 grs is 3100 +\- fps and typically very good accuracy. (Sons 24” barrel with WW brass and 57 grs does 3150 fps with 130 BT)

+1 to Scotty’s comment …. 25-06 and 120 s are slow powder territory. That said you s/b able to find something acceptable with IMR4831…. Maybe not quite the velocity of Retumbo, R26, etc but still a nice load. IMR4831 has been very good to me in a number of 270 s with 130 gr bullets 👍

Got it on R33 too; as someone said, looks like the norm for all Alliant powders.

Not 300 BO, 7.62x39 !! Sorry for confusion.

Got a like new, in perfect condition Oregon Gunsmithing (Wayne York) Howa Mini metal hinged bottom metal, magazine and follower for a 6ARC, 6.5 Grendel or 300 BO. $150 TYD in continental US. Cross posted so first I ll take it wins! Thx

Nathan, just curious, do you hand turn your necks or have you built a fixture of some type to turn on your lathe? Guy I know here locally built a fixture and drives cases onto spud in lathe and them cuts them with a carbide bit and has dial indicators on lathe carriages, etc. Pretty slick deal...

All good choices. 72 grs of R22 with 200 AB was “plenty” of medicine for my moose. Recovered a perfectly mushroomed bullet bullet in the offside with the skin having hung onto it. You should have a load worked up quickly with the Jose powder choices. ( In my rifle I got a load submoa fairly...

H380 was too slow in my bolt gun loads. I d say LVR or CFE223 is about the slowest yo use. You can go from TAC to LVR with 90-110 gr bullets. Real light, like 70-80 grs and then can use some powders even faster than TAC or H4895.

The old Hornady 139 interlock, both SP and BTSP, has always shot really well in 7-08 s for me. It has a short bearing surface and 2840 + fps is really easy. With a 24” barrel rifle I ve gotten to upper 2800 s and 2900 fps ish. Quite affordable too !

To expand powder choices, VV N540 or N550 would work nicely along with others that have already been mentioned
