Speer Load Data

I’m looking for load data for the Speer 52 grain HP Varminter using H335–hoping someone here has the Speer loading manual. Need the Min/Max load for H335 and OAL.

I contacted the company already but they’re closed till Monday and wanted start working up a load this weekend.

Thanks in advance.

Never use a single source for a load work up… just from lessons learned category.

Now try here for approximate data:

Thanks, that was the first place I checked but the closest data they have was for the 53 gr hp–not sure but wanted to check the Speer manual to see if C.O.L varies.

I hear you on working up a load–I’ll check a few different sources before I get started.

In my Speer manual the 52 gr HP data (Speer part No. 1035):

COAL tested: 2.200"

Start charge:
H335: weight 24.5 muzzle velocity 2879

Maximum charge:
H335: weight 26.5 muzzle velocity 3129

I never rely on a single source…

Thanks very much chaotik–the COAL is the same as the Hodgdon data. The starting load helps too.

Out of curiosity, how many other references for data do you source and do you average between them for a starting min load?

I’ve been using my Lyman manual for load data and cross referencing with the particular powder manufacturer’s as well. I haven’t actually used a bullet manufacturer’s data until now for this load.

I have the current Nosler, Sierra, Speer, Hornady and Lyman manuals, as well as the Hodgdon 2013 annual.

When working up a load I will look at the data from all of these sources. Since there are frequently differences I tend to use the most commonly recommended load as a start.

I do not intentionally average the data.

While a slightly different bullet - I run the 52 A-max and 52 BTHP with 24.5 gr of H335, COAL 2.230. I have had better accuracy at 2.230 than 2.200.

24.5 gr with a 52 gr is plenty warm to run most AR’s. Although much of the data floating is a great starting point and for the most part reasonable, some is TOO HOT for semi auto weapons. I have tested some 52 gr w/25.0 and 25.5 H335, and both of these occasionally pierced some of the CCI-400 primers I was using at the time while I was shooting in 80F+ summer temps. I know that CCI-400’s have a thinner cup, but they generally do not pierce unless there is some legitimate high pressure involved. Just some observations for those pushing for max velocity.

Load OAL to mag length, and as far as starting point on a load. Find similar (heavier)weight, and use that as start. Heavier bullet same powder…

From Hogdgon! Not the exact bullet but it will get you started!:smiley:
