6x45 (223) accuracy loads

[Frankm]

Friend dug out a Rem 700 in 6x45 that he's had for years and hasn't shot it yet. He 'finds' more guns in his collection that he's forgot he had than you can believe.

Anyway, would any of you guys with 6x45 experience and 70-80 grain flat base bullets share powders, velocities and charge weights you had success with? Research I ve done to this point mentions H335, H322, H4895 and H4198 as all good candidates. He has all these powders and more.

Back in the day the 6x45 was one of the good ones for short range benchrest accuracy. ( The PPC and BR case took care of that)

Thanks for any suggestions!

 

[7887mm08]

I use imr8208 with 70 gr sierra blitzkings

 

[dolek]

I use H4895 and H335 ,both with Speer 70 grain TNTs . Both are very accurate at 100 yards . I started low and went up the charge range and found best accuracy on the low end with both powders .Mine is 1/8 twist .

H322, don’t recall charge weight

I think youre thinking of a 6x47 (not the current 6x47 im speaking of the 222 cased one)
Me and @bc’z shoot the 6x45 here and there. With the 62-68 gr bullets they like any powder that a 6ppc likes. I use n133, h322, xmr8208, etc.

62-70gr bullets with H322 in my 12T 6x45

 

[rjtfroggy]

I have a 6x45 on a Savage action, between 23-24 grs. IMR 4895 shooting 95 gr. SMK's, shoots like a laser at 100-200 yards.

I got great accuracy with the H-4895 but not so good on velocity. When i went to IMR-8208, it was like Magic, accuracy and velocity both.

Shot this on Monday out of a AR15

I picked up a couple pounds of the h322 to play with next along with 68gr barts dominator bt.

I use 80 gr sierra #1515 and 80 gr Nosler BT bullets with 27.0grn IMR 8208XBR and Fed GM205M Primers. Right at 3000fps and very accurate in my 700 Remington with a 1:10 twist Pac-Nor Barrel.
I also have an AR-15 6X45 1:9 Twist barrel and use the Sierra 80 gr #1515 bullets with the 27.0grn IMR 8208XBR powder and Fed GM205M primer. 2839fps it also shoots well.

Mine is in a bolt gun- a model seven with a #1 barrel on it in 14tw. Its a coyote harvesting machine and eats up the odd lots of bullets and powder left over from the ppc just like it was designed to

Was going to stop at 5 shots, and decided to keep shooting. 6 went into same hole, 7&8 could have been nervousness or excitement, or that damn milspec trigger I haven't changed yet.
500, 80gr dominator's showed up here yesterday.

 

[Frankm]

He's planning on starting with 80 grain Sierras and H335 and H4895... sounds like we re on right track. Don't know if he's got any 8208

 

[venatic]

XTerminator is very good. Ramshot has reloading data online.

I'm thinking your handle looks very familiar listed on some load data for the 6x45?
