Might your 224 WB barrel speed up 75-100 fps after a 150-200 rounds through it?? Typically my experience with a new rifle.

Is tightgroup a flattened ball powder or flake? I don’t have any yet?

Thanks for info. Pls share your results as you progress… I m interested in doing this same deal for my 20” Howa SL in 7-08.

Thx for sharing…. Guessing a 150 gr bullet with 6.5-7.5 grs of tight group would be safe? Could use my chrono to see when velocity was 1000-1050 ish … Are the loads fairly quiet and assuming no hang fires with the minimal amt of powder in the case?

You ve gotten lots of good advice here. My input would be any properly constructed large game bullet (moose are large 😁) between 150-175 grs will do the trick as long as you put it in the correct spot! Let your rifle decide which bullet in these weight ranges it likes best based on...

Or people have cutback on hoarding thus seconds staying in stock… lots more primers and powder available anymore…. I d say same reason; people have as much as they want/can afford at the extreme prices that have been prevalent!!

Thank you Dr Mike!! I ll look these over and get a “plan of attack”!! Much appreciated.

Ordered a new Howa Superlite with 20” barrel in 7-08. Since it’s a 9.5” twist, and will be 5.5-5.75 pds with scope thinking I ll use 120 and 139/140 gr bullets to help offset some recoil. Dr Mike or one of you fine fellas, would you mind running some QL s for me with 120 prohunter and 139 Hor...

If you can find SP pistol bullets for the calibers you re reducing loads on they work real well. They were designed for those lower velocity bolt action pistols back in the day.

I would think N550 would make a nice load with a 120 gr bullet. I use it with 139-140 gr bullets.

R22 with 180 should provide a good accurate and fast load somewhere between 74-76 grs. (75-75.5 is often a good spot) work up. IMR4350 and 70-72 grs should also be a good area. Guessing it ll be slightly slower fps wise than R22 but should provide good accuracy. Good luck.

I d “guess” 140 s and down. 120 gr might be best weight for TAC in 7-08. Just be cautious and work up.

Varget, H4350 and H380 have all worked well in 4 different 7-08 s I ve loaded for when running 139-140 gr bullets. Don’t rule out H4895 if you want to reduce recoil and knock 200-300 fps off the velocity. Those loads will still go 200-250 yards and take down deer/antelope game when using 140...

My 26” barrel is running near identical velocities to Fotis… 3350 fps with 147 Eldm. I m using 89 grains of US 869. I started around 85-86 if memory serves me right. Good luck

Maybe a grain or two under Eldm 147 starting charges ….?? You have access to a chronograph also?

I remember in the 80 s having to go to the Marina in Heyburn to buy some CCI250 s that I located and the price was quite excessive …. $10 a K !! That was unbelievable as in the late 60 s I could get them for 70-80 cents per hundred; inflation .. 😂

Been seeing them more regularly here but the $89.99 a brick still turns me off as it’s $95 out the door with tax. Preferably a $69 price will entice me much more as that $75 out the door or roughly twice pre-Covid prices. Seems double old price is the new norm for most everything from food to...

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 …
