Ideas on Loads for 243 Win with 1 in 10 Twist

[JTinIN]

Looking for ideas, recommendations and options for loading a 243 Win (Rem 700 HB) with a 1 in 10 twist (listed not measured yet) with 85gr plus bullets (currently trying a 95gr Nosler BT). Most of the shooting is this side of 400 yards with a few trips out west tossed in for 600 yrds to a mile* ;-)

Should be a few threads on this topic, however, was only able to find discussions on 1 in 12 twist or 105/107 very low drag bullets that need faster than a 1 in 10 bullet per the bullet manufactures (a new barrel someday, but not this year ;-). IF this is due to my poor searches, can kill this thread once pointed in the correct direction.

* Note realize the mile is shall we say a little bit distant and better left to the 338LM and 50BMG, but when you get the chance always find it interesting to at least try for the larger targets at a shoot.

I have a box of 95 gr VLD and a #7 taper Shilen select match 6mm 10" twist barrel blank.

I am hearing they will not work together

My Nossler 95gr load was 42gr of RL22.

Amazingly accurate out of a factory Sako 75.

no one has mentioned the 87 gr V Max, they are made for a 10 twist bbl. THat's the only way to go.

The 87gr V max with a BC of 0.400 has a little bit better BC than the Nosler 95gr BT. Will have to give them a try.

Thanks for the ideas everyone.

How about the 95gr sierra matchking? It has a better bc than the 87gr vmax. Should be stable in a 1 in 10 twist.

+1 on the 87gr V-Max. Extremely accurate, fast and spectacular on game. Just waiting on a 20MOA rail and Manners stock then I shall be shooting mine out to 1000.

If your 10in twist 700 can stabilize 100g or more depends in part on what altitude your shooting.
My 243 700 1:10 twist shoots 105amax and 107smk but I'm at 4500ft.

107smk will go abit under .5 at 300y only pic could find is the 105amax which best group has been about .5. 4831sc 39.5 to 40.5g gave best loads using OCW method.

Favorite 243 in Manners stock behind 22 trainer

In my 1:10 I got the best accuracy from 42.5gr of RL-22 95gr Nosler. In my 1:8 the best was 42.0gr RL-22 with 105 Bergers. Ramshot Hunter in the 41-42gr range did very well in both also.

Clark, Walt Berger says the 95 VLDH will do fine in a 1:10 but I have never tried one.

I am looking at the web site
http://www.bergerbullets.com/

And the 6mmVLD are 9" twist.
That means 9" or less.

I would say they must be absolute numbers which is understandable because he also told me many 1:9 would stabilize the 105 and all 1:8 would do it. The website lists the 105 as 1:8 only.

Re: Ideas on Loads for 243 Win with 1 in 10 Twist

From the above link to 6mmBR thread I started about 95VLD stabilization, you can read there have been many who have tried.

I personally have shot 75 gr Vmax from a 14" twist barrel at 2900 fps.

I did a 0.1" group at 50 yards and keyholes at 100 yards.

A big problem here is that the velocity variable becomes important when near the edge of stability.

What does it all mean?
A guy could get great groups at a 100 yard range, and then get terrible results while hunting at 600 yards.

Thanks for the ideas and loads.

Have been reading on the OCW loading, after several dozen years of massive matrixes around listed "accuracy" loads sounds like an interesting option to try. Any experience with OCW appreciated.
