700ML factory barrel loads??

[10ga]

Well have spent 4 weeks wringing out an upgraded 50 cal 700ML. Factory 50 barrel with boltnose and plug to shoot BH209 and can't get the accuracy I want. No, it's not the base/rings/scope and I'm using a sled. Haven't tried any heavier bullets as don't have anything but 300 gr 458 BO and aint using them for smoker testing, a few of Speer but they are already in vials ready for my ML2. Any favorite loads out there in BH209 that give accuracy, good accuracy. Right now the best I'm getting is + - 4 moa and that is unsatiafactory for what I want. My new Bestill Omega/Brux 45 shoots great lights out but the 700ML smoker is for my son in law and I'm trying to get him to move up from pellets and belted bullets. Any insight and load info will be appreciated. Thanks, 10

The 250gr. xtp or sst and 300 gr. xtp's knurled to about .455 in a harvested smooth black sabot
and 90-100gr of bh-209 shoot good in my 50 cal. 700ml. Mine needed to load pretty tight to shoot well.

I had the same thing with my daughter’s 700ML. I settled on 90gr BH209 with a Barnes 250gr TMZ (yellow supplied sabot). It still had vertical stringing but was acceptable at her range limit. It now wears a 45 PacNor barrel, I don’t miss the factory barrel at all.

Barnes TEZ-290's along with weighed charges of BH209 between 70-80gr (in 1-gr increments) along with whatever sabot fits with the right amount of snug, will get it done.

Might try.

92.0 Grs by weight of BH209
.502” Dia. 250 Gr Thor Bal Tip
Smoker BP with 5/32” PFC & Primer Shelf for Crush Fit
Fed 209A
2,157 fps ?

This shoots extremely well in my Co-Workers rifle.

thanks for all for the information and experiences. When the holidays are past I'll get back to the range. Merry Christmas to all. 10

Mine shoots 1.5-2" groups @ 100 with 105 gr eq BH 209 and Barnes 300 Xpanders, 290 TMZs, and 290 T-EZs, all in their supplied sabots.

Knowing that you are not an newbe at what you are doing and knowing the Remington 700ML as I think I do... I am really wondering if your problem is not under the barrel.

In the beginning when Remington was producing the Remington 700ML with the 24" barrel they actually took the time to bed the rifle correctly in the stock. When they switched to the 26" barrel they were not a inclusive on how the rifle set into the stock.

I am thinking "barrel harmonics" might be changing from shot to shot because of movement of the barrel in the forearm of the stock. Actually if you have shot the rifle enough you will see smooth black rub marks in the barrel channel. Another check that can tell you some thing.... when you remove the actions screws does the rifle pull right out or does the barrel stick in the barrel channel someplace. Remington suggested floating the barrel or sanding the channel to provide and equal pressure all along the barrel.

Anyway just adding some thoughts...

[bestill]

I would definitely be looking at stock bedding and barrel channel comtact for uneven pressure.
Leave front trigger guard screw almost loose.

Also some of the 26" barrel crowns were pretty bad.

Sabotloader and Bestill, thanks for the reminder. It is in a Boyds lam TH stock. One of the few of my rifles I've not floated barrel and bedded action and it looks like it could benefit the most of any I've ever had. Getting very inconsistent accuracy shot to shot and session to session. It was so inconsistent didn't use it to hunt any this past season and now back to trying to make it shoot better. Didn't want to have to rebarrel as it is intended for son in law & grandson and don't know if he'll be a pellets and 20 pak of bullets guy or a real shooter, just so he's taking Grandpaw Bob hunting. Thanks, Now to dig out the JB Weld and do a float and bed job. I'm expecting that to help a whole bunch. It is a 24" barrel. Thanks to all. 10

After float/bed job and testing will post outcome.

I've had a Remington 700ML since they came out in the 90s. THE load is 100gr of Pyrodex Select (not just RS but SELECT) under a Barnes 300gr MZ Expander. My gun has CONSISTENTLY shoots almost 1 hole at 100 yards thru all these years. It never shot the 250gr MZ Expander or any other bullet/sabot combo nor would it shoot any brand or any combination of pellets anywhere near as accurately so I stuck with what worked.

Unfortunately I loaned the weapon last year and the guy hunted in the rain with it and now my barrel is ruined.

Well, we all know what to do about that, don't we?

I bought one over the 'net which was SUPPOSED to be in good condition. HA!
Fortunately, it was about to be a donor....good thing. The barrel was toast,
the inside of the action was rusty, and the firing spring was weakened with
rust. The outward appearance was almost pristine, though.

The action cleaned up real nice as did the inside of the bolt. After a
Hunter bolt nose kit (in which the firing spring is also replaced), a .45
barrel, and a new trigger made her a REAL front stuffer.

Sorry to get off topic, 10ga, just wanted people to know ya don't have
to give up on a 700ml just because the factory barrel is history. The
action is actually one of the stronger actions made by Remlington.
