Have a Remington in the safe collecting dust awaiting a winter project. Would like to use this rifle with 220 grain Partitions.

Are the stock barrels and there rate of twist good canditates for this bullet?

I just recently began testing 220 partitions in my 300 RUMs.
So far good accuracy and speeds with them using H870. With a 26" barrel around 3100 cronoed.

Please keep this post updated!!! I've had great luck with 200gr Accubonds and RL25 in my factory barreled 330RUM. Will be trying 208gr A-Max next.

I'm very interested to see what you get with the 220Partityion.

In my .300 RSAUM, 1-10 twist using R-19, 200 grain Partions give a nice little five shot hole @ 100 yards. Just as good as Berger 200's. This is the only time I have had NPT's shoot that well.

That 220 Partiton has worked great for me in the 300 Win Mag, so I would think it should be great in the RSAUM too.

You guys got me confused I thought we were talking RUM not SAUM
