Howdy...does anyone have a guess why a 200 gr FTX (polymer pointed nose) Hornady bullet has a slower muzzle velocity than a Hornady 200gr round nose? Ooops!Forgot to mention this is for a .35Rem.



I use the FTX with a 30-30 pump. They are really accurate and expand well.

Published in every reloading data set that has the Hornady 200gr FTX and Hornady 200gr rnd nose listed together.

Ya I have noticed that as well. But if you buy loaded FTX ammo it claims to have around 2200fps.

I'm guessing that they rounded up from the 2116 fps listed in load data. I think Ganderite has hit it on the head. The spitzer shape bullet probably has a longer shank to attein the 200gr. weight.

So, I compared the lenght of a Cast 200gr. FP bullet (0.846") to the 200gr. FTX (1.090").

If you place both bullets side by side matching the crimping grooves, you can clearly see that the FTX as a longer shank, something like 0.151" more. So it may be safe to assume that case capacity is impacted and thus less powder is available to propel the bullet...
 
I would be interested in seeing comparative data at longer distances than muzzle velocity. I wonder how/if the spitzer shape makes up the difference, if you are using the same components for both the RN and the FTX.

Well, you could try going to Hornadys site and using their ballistic calculator. Should be able to find ballistic coefficients on the hornady website. Otherwise all you need is bullet weight and muzzle velocity I do believe.
 
Or, you could just buy a box or two of Speer 220gr flat nose bullets, load them to 2200 fps (which is not hard at all), go hunting for the rest of your days, and kill everything from marmots to moose.

My Marlin behaved like a much bigger rifle with that load. Guy up here was so impressed with it, he traded me straight across for a 375 H&H.

When I loaded 35Rem for a Rem 14 and a Marlin 336, I used the 220 Speer. Also used in my 358Win. Great bullet.

Note: For the tubular mag I filed the lead tip off to make it a bit flatter and fatter -and safer.

From QuickLoad: the 220gr Speer with a BC over .3 carries the mail quite well.

Code:


Cartridge : .35 Rem.
Bullet : .358, 220, Speer FP 2439

Barrel Length : 20.0 inch or 508.0 mm
Powder : Accurate No.2520

Ball C2 works just as well.

Seating depth is only one issue... I have noted that Hornady (and now Hodgdon) has changed their data for FTX bullets over the past year to softer MAX loads... I wonder if there were failure issues? I am using the FTX in .30/30, .35 Rem, .358 Win, .44 Mag and .45/70... I still load to previous heavier MAX levels and have not had any problems...?

If you are referring to the bullet guide at the front of the Hornady manual it is because of bullet construction, meaning jacket thickness and lead core hardness. If you look a few pages back at the .308 150 grain round nose and 170 grain flat point the velocities are also much lower because these bullets are designed for the 30-30.
 
Several guys are wondering about the 220 gr Speer loaded to 2200 fps. I just edited the Quickload table I posted earlier in this thread, explaining that the blue text is my editing, NOT a "blue pill" pressure warning from Quickload. Guess I should have used Green. ;)

The pressure is almost exactly the same as those established by SAAMI for the 30-30, so are certainly safe in a Marlin.

Also, you will be pleased to note that the velocities are from a 20" barrel.

Yes: the FTX has a long bearing surface and you must load to the crimp grove to function properly in a Marlin. It takes up case space and you cannot get enough powder in the case.

I use 37.5 grs 3031 with 200gr Hndy:RN and have never looked back.
