Here's My Dilema:
I Have Just Finished a 17.5 inch 336 MG .30-30 JM Project Gun.
Now I Need to Develope Loads 4 It.
It Shoots the Lee 170gr RNFP Very Well. (Doesn't Like 150gr Jacketed as Well)
So....This Will be My Boolit of Choice.
I Have 3 Appropriate Powders On Hand: H-4198, LVR & IMR-3031.
So Far She Seems to Like 27-28gr of 3031 & for Close Range 20-21gr 4198.
With the Full Length Barrel(Before I Cut Her to 17.5in.)
She Liked Lower Charges of LVR w/ This Boolit (30gr)
& Had Poor Accuracy w/ Charges of LVR Over 33gr.
Also, I Can Get SR-4759 in Town. Would It be Worth Trying?
Which Powder Would Y'All Recommend? & Why?
This Gun Seems to Like This Boolit at Around 1600-1900fps.
What Should I Do Now?

Posted By City Slicker :
(Quote) I like both your choices of H4198 and IMR3031. They have a good burning rate and fill the case fairly well for shooting cast boolits in a 30-30. I also like RL-7 for the same application. It falls in between as far as burning rate. plus it meters well if you throw your charges from a Uni-flow or the like. You should be able to find a good load with the powders you have on hand.
Good luck. (Quote)

Thanks City Slicker,
I'm Leanin' Towards the 3031. But, I've only Got about 3/4lb Left.
Should Be Enough to Get Me Thru these Lean Times.
Just Gotta Find out if 27gr Shoots Better than 28.
Have a Box Already Loaded. Just Gotta Fix the Jeep First.
Anyway, She's Sighted In @ 50yds & I Can Shoot Off the Front Porch @ 54yds.
Had Great Groups w/ Light Loads of LVR & Have Almost a Full Pound of It.
Got Plenty(3lbs) of 4198 & I Know She Likes It. So I'm Good There.
Thanx 4 your Reply,
US58

use the powder that gets you the highest velocity at the accuracy you need. start with LVR, then 3031, then 4198.

more velocity means better performance and less holdover.

Not Necessarily,
Here's how She Shoots w/ Cast 170gr RNFP w/ 28gr IMR-3031 @ Approx 1974fps:

DSCN0783.JPG
8rds @ 50yds in 2-3 Shot Strings (Till Barrel Got HOT)
Plenty Accurate & Plenty of Power for Whitetail Out to 70-80+yds.
Think I'll Save the LVR for the AI Chamber Mod. & Jacketed 170gr FP.

Attached Thumbnail (Below) is 2nd 8rd Group about 5 min Later.

plumbum,
As Far as My Bolt Gun is Concerned (Velocity Is My Friend w/Jacketed) To a Point....
Midrange Loads Tend to Be the Most Accurate. (2652fps w/ 165gr in .308WIN = <1/2in @ 100yds)
Contrary to Many Here.. My Marlins Tend to Like a Little Slower Velocities w/Cast.
Especially My .444 (Under 1400fps w/ Cast)
Now, The .30-30 May Like Cast a Lot Faster (1900-2000+fps)
Still Testing. With It..... HOT May be Good (Or Not/ We'll See)

Startin' 2 Look Like 3031 & 170's Are "Bread 'n Butter" 4 the .30-30.
Makin' Me a Believer. :biggrin:
Still Like the Way that the 4198 Loads Shoot. Same Boolit/Less Kick. :congrats:
And, Not That Much Slower. (Just Under 2000fps vs. 1800fps?)
Gonna Hafta Compare Accuracy between the 2 @ 50-75yds.

The fastest powder in a long barrel will almost always be the fastest powder in a short barrel.
The most consistent powder in a long barrel will almost always be the most consistent powder in a short barrel.

Cutting 2" off... not a big deal.

Keep running what you've got, and don't sweat the minor change in barrel length. :top:

The correct answer right there. DP

Your old favorite load most likely be will be your new favorite load....."most likely".
I'd venture you'd find 25 to 27 grains of Reloader 7 behind a 160-180 grain cast bullet to be very satisfactory for deer and pigs, rocks, tin cans, tree rats, and varmints of all sorts.

I have yet to find the "perfect load" for my 336 but in afraid when I find it, I will have to look for another one in short order with the powder supply being what it is.

Think I'll just Load Up 40rds w/ 28gr of IMR-3031 w/ 170gr RNFP 50/50 WW & Lino w/ Alum Gas Checks.
They just Shoot So Dang Good.
Then I'm gonna Load Up another 20rds w/ 21.8gr H-4198 & the Same Boolit.
But This Time, I'm gonna Cast Some of those Boolits w/ a 60/40 Mix of my 50/50 Alloy of WW & Lino w/ some Pure Lead & use Copper Gas Checks, Instead of the Alum. ones I've been Using.
Thinkin' that this Will be a Better Mix 4 Huntin'.
If these Shoot as Well as I think they will,
Then I'll Cast Some More Boolits & Load up 40 More w/ This Recipe.
Also gonna Try 20rds w/ 33.6gr LVR & the Hard Cast Boolits w/ Copper GC.
Gotta Cast More Boolits Anyway & Been Wonderin' 'bout Usin' a Softer Alloy Mix.
Got Plenty of Pure Lead & Lino. Need some More WW though.
At least this will give me the 100rds I Want to Have On Hand.

C.T.
May just Have to Try Right At 33gr of the LVR.
You & Several Others have Posted that Same Charge for 170gr Cast Boolit.
Thanx,
