25cal 10 Twist with light bullets

[SBOOMER]

Does anyone have real experience with a 25cal/10 twist barrel and light for caliber bullets? I have a 30” BRC blank and am plotting a 25Mashburn Bee build on a single shot with the sole intent of paper punching at 100 yds. That said, I would hope to shoot 70-90gr bullets at mild velocities. Thanx!

I have experience with a 10 twist 25 Grendel using that range of bullets and it shoots great out to 200 yards.

 

[Preacher]

Shot a 257 JDJ in a 14" Contender with a 10 twist and 85 grain bullets for a lot of years, and a lot of deer...

Rem 700 Classic 257 Bob LA 1:10” 3500 fps with 75 gr V-Max and 50 gr H414, 2.9ish” oal. Sub MOA in my rifle. This was my std groundhog load since I was 9.

 

[std7mag]

I'm shooting a Ruger 77 MKII in 257 Roberts with the 75gr Sierra HP Varminter, and 90gr BlitzKing.

Stevens 200 rebarreled to 250 Savage. Again, buth bullets shoot well to 400 yards.

One of my favorite rifles is 25/06AI with an old Adams and Bennet Varmint blank that I threaded it for a Savage LA. It was on sale at midway for about $80. At the same time they were clearencing out their 87gr Speer TNT Moly coated bullets for around $8-9 a box.(this was a number of years ago) I bought 1000rds of bullets and the barrel with the intention of hot rodding the snot out of it. At the same time Magpro powder was on sale and I thought to myself, “Let’s unleash this thing on some prairie dogs! No mercy!” Well...I fired a few fouling shots zeroing it in and then a few more.... and it would just make little clover leaf shaped groups at a hundred yards! I was working a few loads up and stopped at a mild load of 3490fps. It shot soooo good that I left it right there and babied it. I just couldn’t roast it, it shot too good. It’s now my go to rock chuck hammer. It will routinely hold minute-of-rock chuck out to 550yds. Lots of solid single shot lightning strikes at that 470-550 range where I shoot. It’s spectacular at 100yds. Never ran it hot. Couldn’t bare to bring it to a prairie dog town. I wouldn’t be able to control myself. Had a 257Roberts that really liked 75gr Horn soft points and these 87gr TNTs too. Both had 1:10 twist barrels.

I have three 25 cal rifles, 1/257 Wea and 2 /25-06's with1/10 twist. They work great with the lighter 25 cal bullets but also give you the option of using the 117-120 grs which may come in handy down the road when your chasing the lands. JMO

The most common twist rate for many commercial cartridges and rifles was the 1:10" for quite a while.

Custom barrel makers often offer the 1:10" first while following up with the either the 1:12" or 1:14" twist for traditional cartridges or cast bullets.

My experience is that all of the barrels I use are and have been 1:10" except for a few where I used the 1:12" for special requests. Dedicated rifles for varmints often asked for the 1:12" for using strictly lightweight bullets. The 1:10" twist rate will do well even when running the 75 grain light bullets.

Kurz,
That’s a pretty comprehensive list. Thank you for the time put into assembling it. The 25/20WCF twist rates intrigue me. Any thoughts on why the slowest rate in the later rifles?

 

[STOMP442]

I have a handful of .250 Savages and the 75gr Vmax, as well as the 90gr Blitz, has shot extremely well out of them. I pretty much use IMR 4064 for everything in that cartridge.

 

[dk17hmr]

I have a 25-45 and a 25-223 I believe are both 10 twist and shoot mostly 90gr or lighter.

My 257 weatherby has a 13 twist or something ridiculous and I burn 75gr vmax out of that.

10 is fine for most 25 bullets.

Thank you, you're very kind but I can't take credit for all of it. Here is the complete list I worked on years ago.

Enjoy!

Just yesterday tested some 70 gr. and 90 gr. Sierra Blitz Kings in my Rem 25-06 LR Rifle with 1 -10 Tw. at 100 yds. It really liked the 70 gr. hot load of 57.2 RL-17 with Fed. 210M primer and the milder load for the 90 gr. of 51.5 RL-17 with Fed. 210M primer. My brass is necked down 30-06 Lapua with definitely turned necks to fit my factory chamber. (Lapua tends to be thicker than other brass when necking down) As usual approach with caution. The group for the 70 gr. measured .197 and the 90 gr. measured .420. This was outside to outside of group deducting the .257. This rifle is probably an exception to what normally comes directly from Remington but I'm very pleased with it. The only mods. is a Timney Calvin Elite B R trigger and the PTG light weight firing pin assembly with Tubb Duo-springs. These rifles come from Remington with the B & C M-40 stock.

Does anyone have real experience with a 25cal/10 twist barrel and light for caliber bullets? I have a 30” BRC blank and am plotting a 25Mashburn Bee build on a single shot with the sole intent of paper punching at 100 yds. That said, I would hope to shoot 70-90gr bullets at mild velocities. Thanx!

1/10 should be good for your desired range of bullets and speed you will be pushing them. I run 100gr nosler ballistic tips at 3650 in my 25SST 26” 1/7 twist and they hold together. Also been shooting a 67gr hammer copper solids at 4200fps.
