Suggestions for load for 200FTX

[bowbender6]

Picked up some 200 gr FTX .452” $21/50 . Thought I would use RCR sabots. What powder or duplex should I try for 200 gr? I have N110,N120,5744,4759,R7,4198 and h322.

It depends on how fast you wnat to go.

One would be a plinking or acurate load not worrying about speed. The othe would be a fast load. I don't know can you reach 2300-2500 fps with a 200 gr bullet without blowing sabots?

I would think you would need a tight fit which the RCR will give you. I also would think the faster powders would be the powders of choice.

It would be interesting to see how this bullet performs. It may be a bit shy on bearing area like the lighter .451 bullets. I think Edge and RB shot some of the Devel bullets and maybe could reflect on some loads.

I tried some of the 185 and 200gr .451 XTPs. Mostly with 4759 which is very similar to N110. Used up to 42gr of it but never found anything that gave good accuracy with either bullet. Had no problem with ignition, but usually 3" to 5" groups with frequent flyers. I often found oblong holes in the target. Apparently there was not enough bearing area to stabilize them properly, at least not with the MMP sabots I used. I checked the fired sabots and found none blown.

I went to the .40 cal 200gr XTPs with the blue 50/40 sabots and got excellent results with typical groups of 1 1/4" to 1 1/2" using the same powder loads. Then I got a PacNor 40 barrel and got 1/2" groups with the same bullets so don't do that any more.

A while back I developed a 3,150 fps load for a 185 gr XTP that did not blow sabots, did not throw fliers and grouped good enough that I was amazed.

The load was 30/60 4759/H322. There is a thread on the old board called "3150 fps"

Then, last month, I found another great load for this same bullet using 30 Gr AA5744. Do not know the speed but from the drops I am getting out at 200 yds I will guess it's around 1500-1600.

So, yes...it may be very possible to not blow sabots with a proper duplex and this 200 gr bullet. I would consult with RB or SW on how they would tweak the load I used to go fast. If it were me, I would reduce the booster to 20 gr and see what happens...moving up gradually...and you may touch 3000 fps.

8-)With a bullet this light weight the sky is the limit as far as speed goes as even a very fast powder won't make a lot of pressure until the bullet is moving.

A basic load would be about 45 to 50 grains of N110. I can't tell you exactly when sabots would disrupt. It may be before you reach 50 grains it may be after but you could expect at least 2500fps with a reasonable load.

To go faster shoot a 65 grain N110/H4198 duplex. I shot these loads way back with the Jada and Devel bullets but I don't recall the exact ratio. Nonetheless a 10/55 starting point will be alright to start and you can work up to 2600 to 2700fps with ease. You might be within pressure limits to go even faster but I won't encourage it without reliable data. I think the last time I was here it worked best around 15/50 but work up to it rather than rely on my memory.

I shot the 200XPB a little a year or so ago. I don't remember what the book powders shot for speed. A 60gr duplex of N110/H4198 shot between 2500-2600fps with no blown sabots. Best 200yd group I got out of it was 5".

Thanks - I think I'll try the duplex - The acuracy with N110 44gr was so-so -3"moa

I don't want to discourage you but this type of bullet isn't likely to be the most accurate you can shoot. Bullets with short bearing surfaces and sabots that have long pedals compared to the bullet both present some problems.

You might very well get them to shoot well enough but if not you might try trimming the sabot pedals to match the bearing surface length.

I think your right but its fun to play, I am slowly learning, by experience what most of the veterans already have learned. But the shooting is still fun

My feeling exactly. I have "reinvented the wheel" a number of times and usually it turns out something like, "Well I'll be durned, that sucker don't work any better for me than it did for RB and Edge". Even the failures can be fun and sure beats being at work or home doing "honey doos".
