Bear with me as I'm a noob to reloading and this was my very first batch of anything.

I swapped some scopes around over the summer and it was slightly windy the day I zeroed it, resulting in the bullets hitting to the left slightly. I didn't touch the scope yesterday while out shooting, as I only wanted the best grouping.

I loaded up 5 different powder charges with 5 bullets each, and 1 more powder charge with 4 (ran out of that brand of brass). All brass was from spent factory loaded Winchester and trimmed to the same length. COAL in all were the same as well.

Gun: Remington 700 BDL 22-250 w/ Redfield 3-9x50
Bullet: Sierra 55gr. Spitzer
Powder: H380
Target: 100 yards
5 Bullets on each powder charge. 4 bullets on very last charge.

I wont go into which groups had what powder charges, unless someone wants me to.

First pic: Top left was 3 factory rounds. The rest were 5 shots each that I loaded.


Second Target. Disregard the center target. This was my 30-06 with factory. The rest were all my loads. Top Right target was the load with only 4 bullets, but is the best load I found.




4 shots and tried to center calipers

Very nice - I'd say you found your load!

IMO, only way to get it any tighter would be to put a black dot in the middle of the red target center to aim at (your group is already the size of the target center!) AND a little higher power scope to see the dot (about a 12x in my experience)!

Good Job!

Thanks guys.

It would have been nice to have a little more scope for sure. This was just an older scope I used to have on my 30-06. Once the 06 upgraded to a Viper vortex pst 4-16, this one got passed down to my wife's gun. I just picked up used Vortex viper pst 6-24 for a build, and once my big scope shows up for it, it may get put on this 22-250.

Bottom left ain't bad either.

You should share the model of gun and all the specs of the load though.

Thanks for sharing good job!

Thanks yall. GazGuzzler, the gun was posted in the first post, but here it is again.

Gun: Remington 700 BDL 22-250 1:14 twist, w/ Redfield Revolution 3-9x50 with 4-Plex reticle
Bullet: Sierra 55gr. Spitzer
Powder: H380
Target: 100 yards
5 Bullets on each powder charge. 4 bullets on very last charge.
I went in increments of .2 grains in each set of 5.

I went through some trial and error on case length and COAL to get the bolt to close, but finally ended with:
Case length- 1.904"
C.O.A.L.- 2.346"

I DO NOT have a chronograph, so MV is unknown currently. Based solely off of Sierra's manual, the MV should be:
3400 MV - 34.2
3500 MV - 35.4
3600 MV - 36.7
3700 MV - 38.0

Pic 1:
Top Left - Factory Winchester 55gr PSP
Top Right- 35.6 gr. of h380 (5 shots)
Bottom Left- 35.8 gr (5x)
Bottom Right- 36.0 (5x)
Center - 36.2 (5x)



Second Pic-
Bottom Left - 36.4 grains of H380 (5 shots)
Bottom right - 36.6 (5x)
Top Right - 36.8 grains (4x) - BEST
Center- Irrelevant to my loading. (30-06 Rem 165 gr. Core Lokt)




4 shots and tried to center calipers

Need to be carful using book mv because a lot of times they will use really long barrels to improve numbers.

Correct. Their manual says they used a 1:14 twist, 26" long barrel. Mine is a 24 incher.

Those are really good groups, the 36.6 should of been close to the 36.8 in groups how long before each set of loads did you let the barrel cool...congrats think you found your load. The looks of some of those groups stringing Rt to Lt can tighten up running out or in off your lands..How far off your Lands are you running, just curious.

I want to thank you this post - you have just ruined my life...

I too have just started re-loading - 250 savage and 300 savage...

I just did not want to believe that 0.2gn could really make that much difference in accuracy !

Seeing is believing - back to the drawing board - Thanks a bunch - LOL

.2 won't matter in medium to large straight wall pistol so Find a Ruger .357 or .44 and load away.

I never would have thought such an incremental amount of the same powder would make such a big difference in accuracy, with a given cartridge and bullet. Nice work.
