Home Forums Lever Action Central Marlin 336 Lever Actions 35 Rem. +P loads

Just an fyi - I think that the Leverevolution load is with a 180 grain bullet...

I wonder if the folks who think that 40K in the 336 35 rem is dangerous limit themselves to lead bullets at 1500fps in the 1895 marlin?

There is always some Chicken Little running around crying that the sky is falling.

"The cases show no signs of pressure and primers are not flattened."

At the normal maximum - and over maximum - pressures for a 336, you will never see "signs of pressure" nor "flat primers". That kind of pressure sign is restricted to bolt rifles working at maybe 60K + psi.

A 336 is stong for a rear locking lever rifle but it will come from together well before reaching those pressure levels.

New guy here. I appreciate all the experience posted. I'll throw in my 2 cents worth.

I load a Speer 180g FP over 41.5g of IMR 3031 for 2400 fps in my 336C (20"). This is a PUBLISHED MAX LOAD from Speer's Reloading Manual Number 9. 40.5g gave 2375 fps. Still a great load with that bullet. You need 2300+ fps with the 180g FP for it to expand reliably. It's a tough bullet.

Thanks for the lively discussion and info.

Hi, DavyG and welcome to the Campfire. We need some Marlin shooters. Be nice but jump in.

The 336 is designed for loads in the 50,000 PSI range. 41.5 works well in my gun, as well as the same charge of 4895. The 35 Remington is a great cartridge in the Marlin.

.

So what do you think that load might run in PSI?

Someone on this forum ran that load thu QuickLoad computer program, QuickLoad said that the pressure would be around 42,000 PSI. But remember, that's a guesstimate not an actual pressure test. At any rate, it is well within the Marlin's limits.
I check my loads on the chrono and try to run between 2200 and 2300 fps with 200 gr bullets in a twenty inch barrel.

.

I hear ya. 200g CoreLokts @ 2200 fps will produce perfect mushrooms; i.e. the perfect velocity for that bullet.

I like the tougher Speer for the hogs. Friend took a 300 lbs hog in Feb, and there's a 400 lbs specimen running around up there with a hole from a .243 that didn't kill him. Those gristle shields soak up energy. But my preferred hog load is a .44 265g WFN hardcast at 1825 fps from my 1894...1.5" wound channel thru-n-thru, no matter the size.

"I have seen 2300 fps on a friends Chrony. He says he is using H-4895. The cases show no signs of pressure and primers are not flattened."

Hot rod your 336 if you wish, but it won't change the effect much.

Anyone who trys it should know from the outset, the low pressure limits of the ammunition apply to those rifles and not the cases. The rifle itself will come from together, violently, long before any important pimer flatening or case sticking on extracton or measureable web expansion occurs.

Just something to think about for anyone who is trying to make his 20" 336 in .35 match a 24" bolt action in .358.

.

I run my 336 at 50,000 CUP that is the same as the 358, so what difference does a bolt action make as far as pressure is concerned? Pressure is pressure no matter what action.

.

jbledsoe,

Do I understand you correctly? Are you saying that a leveraction should be able to handle the same pressure as a bolt action? Sure pressure is pressure but some actions are designed to handle more pressure than others.

There are tons of differences between a marlin 336 and a bolt action. First is where the action locks, the marlin locks near the rear of the bolt and a bolt action locks at the front. The rear lockup allows more movement. The thickness of the barrel around the cartridge is also thinner on the marlins due to the way the magazine comes into the reciever. Most bolt designs are much stronger.

Bolt actions are also made to direct gas from a ruptured case or a blown primer out to the side, that is what the hole is for on the side of savage 110s and remington 700s. Marlins dont have this feature and most of the gas is going to travel either along the firing pin or along the outside of the bolt, either way its going straight toward your face.

If you feel safe with your loads in your rifle than so be it. You are probably safe at those pressure becuase marlin chambered the 356 and 375 winchester and I believe they were rated up to 52000 psi (dont quote me on this because I am not 100% on the pressure). I feel safe loading my 35 rem up to about 42000 psi so I am not saying you shouldnt load above published data but just know that the 336 marlin is definatly not as strong as just about any bolt action around.

.

Thanks for your reply, JB

You read correctly but I said that pressure is the same whether in a bolt, lever, pump, or other. Some posters implied that a lever gun designed to operate at 50,000 CUP was far inferior to a bolt gun designed to operate at the same pressure. Shooters continually degrade the Marlin as being a weak action. Just because the 336 is chambered for a 30-30 designed to operate at a max of 38,000 CUP does not mean that the rifle is not capable of higher pressure. The Winchester Mod 70 was chambered for the 30-30, does that does that limit it's max to 38,000 ? No, in fact, I know some mentally challanged shooters who run their Mod 70s at 70,000 to 75,000 PSI. BTW you may notice that your Mod 70 does NOT have a gas deflector at the back of the bolt to devert gases, gas follows the bolt to the shooters face.

The 375 Win run at 52,000 CUP not PSI, CUP and PSI are not the same. That would be close to 60,000 PSI.

Browning and Savage lever guns are much stronger that many bolt actions guns. Comparing weak lever guns to stronger bolt guns is NOT a valid compareison.

One of the strongest bolt guns is the Remington 788. Guess what, the 788 has rear locking lugs and not front locking lugs.

The Krag the 95 Mauser and the early Springfield 1903 are all bolt guns but none are as strong as a Marlin 336 or 1895 (which is also a 336 with enlarged ejection port) The 1895 is maybe a little weaker than the smaller calibers because of the larger dia. 45-70 case thus less metal around the cartridge.

This is intended for information only, not in any way as a "put down". JB ask a valid question and I tried to answer at least in part.

JB,

I get what you are saying now. I miss understood what you were trying to say at first.

MontanaMarine Why not look at the 356 Win. 220 in the 2300
range and the 250 in the 21 to 2200 range . Might be what you
are looking for. Cheers NC

Buffalo Bore loads a 220 JFN at 2200 FPS. Don't know what pressure it runs. While I am sure you can load a 35 Rem. to higher pressures than the factory, I've never understood the rationale of trying to make an apple an orange. What practical gain do you hope to get from hotroddin' this great round that is not easier to achieve using a .356 or .375 Win or for that matter a 45-70 or 450 Marlin?

Life must be dull. But it will not be for long if you are running you 45-70 or 450 Marlin at 2200 fps. (LOL)

.

I am also working on some +P loads. In particular:

180 gr Speer - 2350 fps

200 gr FTX - 2250 fps

220 gr Speer - 2200 fps.

These should all keep the pressures in the 40,000 range. I don't think you should push a Marlin much over 42,000, but I'll also shoot these in a 760 Remington which should handle a lot higher (50,000) pressures.

Here, here, well said!!!!!

For those who just have to ask why.

I love being at sea during a storm, I love driving fast cars over the speed limit, and I love reloading for the guns I own. I want to get the best out of each of them. Some say I'm crazy, so be it.

I hate flying and am scared [bleep] while you say flying is nothing to be afraid of its one of the safest things in the world. If you think so let me ask you this Are you willing to trust your life to a complete stranger to drive your car as fast as it will go while you are blindfolded? No, then why trust one to fly you anywhere at 5 times the speed your car will do and you can't see out the front either?

I won't ask you to give up anything you love to do; PLEASE show me the same respect.
