"Is that a gas check design?" Nope just a plain base bullet. Gas checks not needed at velocity under 1600 fps. and no need to go over that with cast bullets.

Advise the nut behind the trigger that the importance of consistent form cannot be overstated. Apply exactly the same pressure in holding the rifle for each shot, same hand pressure, same cheek pressure, and same shoulder pressure. Marlins are very sensitive to pressure. I can change impact point just by holding the rifle differently. Same with the cross sticks, they must set exactly the same each time.

We shouldn't tell you all of our secrets, we may have to shoot against you one day. ;D ;D

Thats very good advice Marlins or any lever gun being so light and with a straight stock and flat buttplate are very sensitive to how they are held shot to shot. Besides sight picture it's probably the most important thing. We talk a lot about loads, any of the recomended loads will win a match if the rifle is aimed well and held consistent.

I really like SR 4759 but I use a grain more (16.5) and out of my CB it just tops 1500 fps with the Lee 250 grain bullet and about 50 fps faster with the Ranch Dog 235 grain bullet. The SD and ES are very low with this load. I was hoping it would give me a right on hold on the 400 yard dinger but I still need to hold a bead over with the factory Irons. I do have a right on hold for the 200 yard Rams with a couple of notches left in the elevator though.

If I recall correctly Wind was having some success with a few more gains than that. Over the chronograph his extreme spread was 3 fps apart, 1701-1704 fps. Seemed to show real promise on paper. Don't recall which bullet he was using.

One thing about my CB is it doesn't shoot .379" bullets very well. Size em to .381" or shoot em 'as cast' and the groups shrink to less than half the size at 50 yards with most of em touching the same hole.

10 grains of Unique seems to work really well. Eleven grains works too but the velocity only increases by 80 fps and the accuracy is the same. Eleven gets me one more notch though at 200 which is the only measurable advantage.

Guys like Shennandoah, Wind, Swany, JBledsoe, 44lvr and GeorgeKY and others will share pearls of wisdom that are worth heeding. Sure shorted my road a bunch. Not many universals in 38-55. Success seems to be rifle specific. Sure is sweet when it comes together though.

I'm surprised no one has mentioned Trail Boss powder.

That stuff shoots good in everything I've tried.

I've even been shooting cast bullets in my .30-06.

When one finds a combo that works in the 38-55 it's very hard to break away and try something unknown. I have some Trail Boss on hand but I also have a large supply of Unique and Unique works in my rifles. Herco also works well in many straight cases, anyone remember Herco? Blue Dot works well in some but my Marlins don't care for it. So back to Unique.

I did use a lot of Unique before I found Trail Boss. I was always a little concerned about the small charges in a big case. I played around with fillers and wads. I checked and rechecked for double charges. I can't say I ever had a problem, but I kept a close eye on it. I'd still be using it if Trail Boss hadn't come around.

I like the way Trail Boss fills the case. And it smokes just a bit. I get some of the Black Powder appeal without the extra work.

You might give it a try when you get some time. Essentially you fill the case to the point that it touches the bullet, but doesn't compress the powder. You can reduce from there if you want to go slower. I've had good luck in everything I've tried. I shoot just about all the common straight walled cases in revolver and rifle.

I've also used it in a lot of bottle neck cartridges, particularly .30 cal. I like it in the .30-30 with 170gr cast bullets. It also did well in the .308/.30-06/.300 Savage/.300WSM. But usually I pick those when I'm hunting and just go back to my usual higher velocity powders.


You have to love handloading. It brings a whole new dimension to the shooting art.

That's why you convince yourself you'll try it in just ... one ... cartridge and see how it works.

Maybe by a new rifle in a caliber you don't have and try it in there?

How about a .40-70?

Do you folks think a reduced load of Trail Boss (not to the base of the bullet), would be a good, safe load in a 1906 manf. date 1893 in 38-55? The rifle is marked "For Black Powder" and is solid, tight, and has a fair to good bore. From what I have been reading it seems like the pressure curve for Trail Boss is similar to black powder.

The correct answer is "have the firearm examined by a competent gunsmith". Ask him. I bet the answer will be "no".

I have also read that trail boss loads have a pressure curve more comparable to black powder than other smokeless loads. I can tell you they feel more like black powder than other smokeless loads. They are very pleasant to shoot.

You can still break 25,000 CUP with trail boss and a 250gr bullet. You don't want to compress Trail Boss.

I haven't seen pressure data on BP in a .38-55. BP is it's own animal for sure. I'd like to see the pressure curve data on a graph before I would make the decision.

Marlin's are tough and Trail Boss reduces very well. But I doubt even IMR will ever recommend you use it in a firearm marked for Black Powder. They would tell you to stick to the manufacturers recommendation on the firearm. And I think debates like that will continue for some time.

No easy answer for the front sight insert.

I use them all, Lymans Redfields MVA's and Mike Stevens on various rifles. Lee Shavers are on many rifles but far as I know present no new ideas so i use what fits the front sight. I prefer aperture if match rules allow and the target can be circled by the sight leaving plenty of light around, it's without a doubt the best way to go. If not and post are required by rule or target size you have to switch around from one to the other figuring it out for yourself

Have about settled on fairly wide black flat top post for black Silhouettes, black thin lolly-pop for White Silhouettes. As soon as the Lolly-pop gets blurry or indistinct I go back to the wide post. Adjusting the rear aperture gives a lot of latitude in front. Years ago I had adjustable front Apertures on my Anschutz Prone Rifle. Quick twist, however I did all the twisting on the rear and never changed the front.
