460xvr&hornady xtpmag bullets

[roger460xvr]

IM loading up some 300gr hornady xtp bullets using h-110 powder at 34.0grs that should be enough to still take out florida deer? what do ya think.. hands are getting old and shooting them full bore loads are a thing of the past..still LOVE MY 460 THOUGH.roger

Title say XTP MAG and you ask XTP
XTP mag is not suitable for 460 use XTP MAG

With H110 you need to keep the case fill at 90% or greater

Minimum load is 38.1 grain per Hornady manual

 

[roger460xvr]

there xtp mag bullets the old usa reloading book says 33.4 to 39 .2 but I checked hodgdon and your right about start at 38.0 to 42.5 thanks for the info before I loaded them up..

 

[ruggyh]

They shoot just fine at min loads for me and group well
They will be no problem on deer or even elk

Speer #14 has some reduced 460 loads using their 300gr UCSP (Uni-cor soft point) bullet & H110. Starts at 29.0gr.@ 1406fps & max. at 31.0gr.@ 1475fps, with standard LRPs, from a 8-3/8" bbl. They're reduced because of the bullet's velocity & pressure (37K PSI max) limitations.

Hornady lists the muzzle velocity range for their (non-magnum) 300gr XTP bullet at 800-1700fps, they have two cannelures, & are within the above load's range.

Thank you again Ruggyh for finding the mistake on the reloading info that I got from the book called "The Complete Reloading Manual the .460 and .500 S&W Magnums". Their info on page 3 is definitely wrong listing a 33.4 start charge, but on page 13 they list the right start charge at 38. I guess I need to make sure I didn't make any bullets at that charge a while back. If so, I need to get my bullet puller hammer out I guess. Thank yall again for all yall's help. Just can't shoot them hot loads anymore with my tired aging hands.

I recently purchased the 9th edition of the Hornady reloading manual so now I have another reference besides my Lyman's 49th manual. Here's the 460 mag data straight out of the Hornady manual:

300 gr. XTP MAG :
start : 33.4 H110
max : 39.2 H110


240 gr. XTP MAG:
start: 41 gr. H110
max: 49.5 H110

Even though Hornady lists starting loads under Ruggyh's suggested loads I would without a doubt vouch for Ruggy's expert 460 mag handloading experiences.

Why would you need to pull them ??

Why risk a hang fire? H110 has been know to do that when loaded below 90% case fill (not weight).

33 grain is 76% case fill. Poor ignition is very possible and in a few instances have seen bullets not make it out of the barrel of a ES (2 and 7/8 inch) were the owner loaded 30 grains thinking it would be ok because he was using magnum primers.

Indications of low pressure when using H110 are unburnt crusty powder, usually tinted yellow. In a few instances the powder will actually be crusted and remaining in the brass.

Hornady as since corrected their data in the most recent printings.

Note many books just copy published data, so printing errors are not uncommon.

Good luck and be safe

Good luck Roger, if you want some other powder suggestions PM me

OK so just to clarify before I scribble corrections in my manual :

300 XTP mag using H110 :

start 38.1 gr
max 39.2 gr ?

Lyman Cast Bullet Handbook #4 lists a start of 29.5gr/H110 w/325gr L-SWC-GC in the 460Mag. That's not 90% of available case volume (ACV).

The Speer #14 load I quoted above (300gr UCSP bullet & H110 starting at 29.0gr.) doesn't meet 90% of ACV either. (~74% by my calculations)

Lyman #49 lists a Speer 300gr GDHP with 34.0gr/H110. That's ~82% of ACV, assuming a bullet seating depth of .400", by my calculations.

Hornady #8 does not list any Update-Errata data for that book's 460 S&W loads other than an A#9 powder entry, which isn't even listed in my 3rd Printing.

Not trying to pick a fight, but why would the above companies knowingly provide "unsafe data" in their books?

[ruggyh]

The powder manufacture provides guidance for their powders.

If a ammo ammo manufacture uses it outside those recommendations then it is their choice and their responsibility.

This is not a new discussion.

Only a few of the reloading books published actually contain data developed and tested by the company; lee for example only collects data from other sources and republishes them.

Hornady and Barnes are examples of companies which develop their own data in their ballistic labs. Same can be said of the powder manufactures whom publish data from their ballistic labs.

Understand the source of your data and how it was developed. If it is in question, I have had no issues with emailing and receiving answers from powder and bullet manufactures.

Loading with H110 is poorly executed by the reloading community in my opinion and poor advice given often.
If you want to use H110 i suggest using the powder manufactures instructions and recommendations.

If you look at the history of complaints about H110 you see they are usually about downloading. H110 and many other powders are pressure dependent to burn correctly if you down load them to far you can expect poor results including barrel obstructions and the rare hang fire.

I will photocopy and post Hodgon data this evening and post here.

In the end it is the individual whom has to take responsibility for their chose, choose wisely.

Good luck and be safe

Jeez talk about a major contradiction between Hodgdon and my Hornady 9th edition manual (2012, 5th printing date). The whole reason I bought the Hornady manual was the fact I kept reading so much contradictions between my Lyman's 49th and the online powder / bullet mfg's data. Looks like all I achieved was more confusion... LOL

I would think it would be fine, especially hunting in the warm climate of Florida. I would use a mag primer tho with that low of charge, but that is just me. Many claim the large case capacity of the .460 does not warrant the use of a mag primer with H110/W296, unlike when used in .357. It also may depend on your firearm. I found my P.C. X-Frame has tight throats and that my max loads for it, are many times Hodgdon's min loads. If you want to go lower that what you feel is safe for H110/W296, I suggest IMR4227. It has become my "go to" powder for .460 giving me excellent accuracy, even when shooting lower charge rates. I have found for deer, one does not have to load the .460 to max for it to be effective, especially for those of us that still use irons and keep our distance under 125 yards.

I've found that in .460, Hornady tends to load mild while Hodgdon likes to load wild. For the little difference in velocities, I tend to load for accuracy and have found that many times, the Hodgdon start loads are the most accurate.

 

[roger460xvr]

The 38.0gr of h-110 shot excellent .. and very accurate. also a little less recoil on the hands. I am very pleased with this load.
